State of the Art Microsomal triglyceride transferase protein (MTP) is a lipid transfer protein which mediates the transport of lipids, such as triglycerides, cholesterol esters, and phosphatidylcholine, between membranes. 1,2 Accordingly, MTP is believed to play a role in the assembly of lipoproteins and related biomolecules. In this regard, MTP has been implicated as a probable agent in the assembly of apolipoprotein B (Apo B)-containing lipoproteins which are known to contribute to the formation of atherosclerotic lesions. Thus, effective inhibitors of MTP would be useful in preventing the onset and progression of atherosclerosis, including myocardial infarction, stroke, peripheral vascular disease and the like, which accounts for one-half of deaths in the United States. 3 MTP was originally isolated from the microsomal fraction of bovine liver and has subsequently been found within the lumen of microsomes isolated from both the liver and intestine. 1 Since its initial isolation, MTP has been extensively characterized. 4,5 ° MTP is a soluble, heterodimeric protein composed of 58 and 97 kDa subunits, both of which are required for activity. The protein is localized within the lumen of the endoplasmic reticulum. The 58 kDa subunit is identical to protein disulfide isomerase (PDI), though the complex exhibits no PDI activity and isolated PDI does not exhibit MTP activity. The noncovalent MTP heterodimer does not display significant dissociation reassociation and is either asymmetric and/or highly hydrated. The unique 97 kDa subunit bears homology to other lipid-transporting proteins, including the lipovitillin-phosvitin complex (LPC) and, to a lesser extent, plasma cholesteryl ester transfer protein (CETP). 7 Structural characterization of LPC reveals that it comprises a large cavity that complexes multiple copies of phospholipid. 8 - 9 Kinetic analysis of the MTP-mediated lipid transport processes have revealed ping pong bi bi kinetics which is consistent with a mechanism of action in which MTP binds and shuttles lipid molecules between membranes. 10 This suggests that stable MTP-lipid complexes are formed during the transfer process, which is further supported by the observation that incubation of MTP with donor vesicles containing a variety of radio-labeled lipids followed by re-isolation affords MTP containing up to three molecules of lipid. 11 12 The ability of lipid molecules to occupy distinct binding sites on MTP is suggested by the observation of biphasic kinetics for transfer of phosphatidyl choline, which binds with a 2: 1 stoichiometry to the enzyme. 12 Moreover, an MTP inhibitor has been shown to fully ablate the MTP-mediated transfer of triglycerides and cholesterol esters but not that of phosphatidyl choline. 13 The ability of MTP inhibitors to prevent the onset and progression of atherosclerosis and related disorders is supported by the observation that mutations in MTP are the only known bases for abetalipoproteinemia, an autosomal recessive disorder characterized by the virtual absence of apoB- containing plasma lipoproteins. 1 2 14 Abetalipoproteinemia subjects are free of atherosclerosis, but they suffer from a variety of side effects as a result of the extreme nature of their condition. This suggests that non-complete inhibition of MTP would be requisite in an agent designed for human therapy. In this regard, hypobetalipoproteinemia is a relevant model for MTP inhibition. This condition is displayed by individuals who are heterozygous for mutations in apolipoproteinB. 15 These subjects have levels of apoB-containing lipoproteins half that of normal subjects and, as a result, they enjoy extended lifespans. Inhibitors of MTP have been described in the patent and technical literature. See, by way of example, U.S. Patent No. 5,712,279; 16 U.S. Patent No. 5,739,135; 17 U.S. Patent No. 5,760,246; 18 U.S. Patent No. 5,827,875; 19 U.S. Statutory Invention Registration No. H1729; 20 WO 96/40640; 21 WO 97/26240; 22 WO 97/43255 ; 23 WO 98/03069; 24 WO 98/03174 ; 25 WO 98/23593 ; 26 WO 98/27979; 27 WO 98/31225; 28 WO 98/31366; 29 WO 98/31367; 30 EP 0 643 057 Al; 31 M. Haghpassand et al.; 32 F. Benoist et al.; 33 and J. R. Wetterau et al. 34 Notwithstanding such inhibitors, a need exists for effective MTP inhibitors having improved biological and/or therapeutic effects. It has now been discovered that MTP inhibitors having surprising and unexpected properties can be prepared by linking from 2 to 10 ligands capable of binding to MTP to one or more linkers. The chemical structure of one known inhibitor of MTP, i.e. BMS-201038, is illustrated in Fig. IA. 1634 Without being limited to theory, a potential complex of this compound with MTP is illustrated in Figure IB. Based on the distinct multiple binding sites believed to be present in MTP, various multibinding compounds are illustrated in Figure IB. Such multibinding compounds provide greater biological and/or therapeutic effects than the aggregate of the unlinked ligands due to their multibinding properties.

The term "optional" or "optionally" means that the subsequently described event, circumstance or substiment may or may not occur, and that the description includes instances where said event or circumstance occurs and instances where it does not. The term "ligand" as used herein denotes a compound that is capable of binding to microsomal triglyceride transferase protein. The specific region or regions of the ligand that is (are) recognized by the protein is designated as the "ligand domain". A ligand may be either capable of binding to the protein by itself, or may require the presence of one or more non-ligand components for binding (e.g., Ca +2 , Mg +2 or a water molecule is required for the binding of a ligand to various ligand binding sites). Examples of ligands useful in this invention are described herein. Those skilled in the art will appreciate that portions of the ligand structure that are not essential for specific molecular recognition and binding activity may be varied substantially, replaced or substimted with unrelated strucmres (for example, with ancillary groups as defined below) and, in some cases, omitted entirely without affecting the binding interaction. The primary requirement for a ligand is that it has a ligand domain as defined above. It is understood that the term ligand is not intended to be limited to compounds known to be useful in binding to microsomal triglyceride transferase protein (e.g., known drugs). Those skilled in the art will understand that the term ligand can equally apply to a molecule that is not normally associated with binding properties. In addition, it should be noted that ligands that exhibit marginal activity or lack useful activity as monomers can be highly active as multivalent compounds because of the benefits conferred by multivalency. The term "multibinding compound or agent" refers to a compound that is capable of multivalency, as defined below, and which has 2-10 ligands covalently bound to one or more linkers which may be the same or different. Multibinding compounds provide a biological and/ or therapeutic effect greater than the aggregate of unlinked ligands equivalent thereto which are made available for binding. That is to say that the biological and/or therapeutic effect of the ligands attached to the multibinding compound is greater than that achieved by the same amount of unlinked ligands made available for binding to the ligand binding sites (receptors). The phrase "increased biological or therapeutic effect" includes, for example: increased affinity, increased selectivity for target, increased specificity for target, increased potency, increased efficacy, decreased toxicity, improved duration of activity or action, decreased side effects, increased therapeutic index, improved bioavailibity, improved pharmacokinetics, improved activity spectrum, and the like. The multibinding compounds of this invention will exhibit at least one and preferably more than one of the above-mentioned affects. The term "mulimeric compound" refers to a compound containing 2 to 10 ligands covalently connected through at least one linker which compound may or may not possess multibinding properties. The term "potency" refers to the minimum concentration at which a ligand is able to achieve a desirable biological or therapeutic effect. The potency of a ligand is typically proportional to its affinity for its ligand binding site. In some cases, the potency may be non-linear ly correlated with its affinity. In comparing the potency of two drugs, e.g., a multibinding agent and the aggregate of its unlinked ligand, the dose-response curve of each is determined under identical test conditions (e.g., in an in vitro or in vivo assay, in an appropriate animal model). The finding that the multbinding agent produces an equivalent biological or therapeutic effect at a lower concentration than the aggregate unlinked ligand is indicative of enhanced potency. The term "univalency" as used herein refers to a single binding interaction between one ligand as defined herein with one ligand binding site as defined herein. It should be noted that a compound having multiple copies of a ligand (or ligands) exhibit univalency when only one ligand is interacting with a ligand binding site. Examples of univalent interactions are depicted below. The term "multivalency" as used herein refers to the concurrent binding of from 2 to 10 linked ligands (which may be the same or different) and two or more corresponding receptors (ligand binding sites) on one or more biomolecules i.e., proteins or enzymes, which may be the same or different. For example, two ligands connected through a linker that bind concurrently to two ligand binding sites would be considered as bivalency; three ligands thus connected would be an example of trivalency. An example of trivalent binding, illustrating a multibinding compound bearing three ligands versus a monovalent binding interaction, is shown below: Univalent Interaction Trivalent Interaction It should be understood that all compounds that contain multiple copies of a ligand attached to a linker or to linkers do not necessarily exhibit the phenomena of multivalency, i.e., that the biological and/or therapeutic effect of the multibinding agent is greater than the sum of the aggregate of unlinked ligands made available for binding to the ligand binding site (receptor). For multivalency to occur, the ligands that are connected by a linker or linkers have to be presented to their ligand binding sites by the linker(s) in a specific manner in order to bring about the desired ligand-orienting result, and thus produce a multibinding event. The term "selectivity" or "specificity" is a measure of the binding preferences of a ligand for different ligand binding sites (receptors). The selectivity of a ligand with respect to its target ligand binding site relative to another ligand binding site is given by the ratio of the respective values of K d (i.e., the dissociation constants for each ligand-receptor complex) or, in cases where a biological effect is observed below the K , the ratio of the respective EC 50 's (i.e., the concentrations that produce 50% of the maximum response for the ligand interacting with the two distinct ligand binding sites (receptors)). The term "ligand binding site" denotes the site(s) on the microsomal triglyceride transferase protein that recognizes a ligand domain and provides a binding partner for the ligand. The ligand binding site may be defined by monomeric or multimeric strucmres. This interaction may be capable of producing a unique biological effect, for example, agonism, antagonism, modulatory effects, may maintain an ongoing biological event, and the like. The terms "agonism" and "antagonism" are well known in the art. The term "modulatory effect" refers to the ability of the ligand to change the activity of an agonist or antagonist through binding to a ligand binding site. It should be recognized that the ligand binding sites of the enzyme that participate in biological multivalent binding interactions are constrained to varying degrees by their intra- and inter-molecular associations (e.g., such macromolecular strucmres may be covalently joined to a single structure, noncovalently associated in a multimeric structure, embedded in a membrane or polymeric matrix, and so on) and therefore have less translational and rotational freedom than if the same strucmres were present as monomers in solution. The term "inert organic solvent" or "inert solvent" means a solvent which is inert under the conditions of the reaction being described in conjunction therewith including, by way of example only, benzene, toluene, acetonitrile, tetrahydrofuran, dimethylformamide, chloroform, methylene chloride, diethyl ether, ethyl acetate, acetone, methylethyl ketone, methanol, ethanol, propanol, isopropanol, t-butanol, dioxane, pyridine, and the like. Unless specified to the contrary, the solvents used in the reactions described herein are inert solvents. The term "treatment" refers to any treatment of a pathologic condition in a mammal, particularly a human, and includes: (i) preventing the pathologic condition from occurring in a subject which may be predisposed to the condition but has not yet been diagnosed with the condition and, accordingly, the treatment constitutes prophylactic treatment for the disease condition; (ii) inhibiting the pathologic condition, i.e., arresting its development; (iii) relieving the pathologic condition, i.e., causing regression of the pathologic condition; or (iv) relieving the conditions mediated by the pathologic condition. The term "pathologic condition which is modulated by treatment with a ligand" covers all disease states (i.e., pathologic conditions) which are generally acknowledged in the art to be usefully treated with a ligand for microsomal triglyceride transferase protein in general, and those disease states which have been found to be usefully treated by a specific multibinding compound of our invention. Such disease states include, by way of example only, the treatment of a mammal afflicted with atherosclerosis, hyperlipemia, hyperlipidemia, hyperlipoproteinemia, hypercholestrolemia, hypertriglyceridemia, pancreatitis, diabetes, obsesity and the like. The term "therapeutically effective amount" refers to that amount of multibinding compound which is sufficient to effect treatment, as defined above, when administered to a mammal in need of such treatment. The therapeutically effective amount will vary depending upon the subject and disease condition being treated, the weight and age of the subject, the severity of the disease condition, the manner of administration and the like, which can readily be determined by one of ordinary skill in the art. The term "linker", identified where appropriate by the symbol X or X', refers to a group or groups that covalently links from 2 to 10 ligands (as identified above) in a manner that provides for a compound capable of multivalency. Each linker may be chiral or achiral. Among other feamres, the linker is a ligand-orienting entity that permits attachment of multiple copies of a ligand (which may be the same or different) thereto. In some cases, the linker may itself be biologically active. The term "linker" does not, however, extend to cover solid inert supports such as beads, glass particles, fibers, and the like. But it is understood that the multibinding compounds of this invention can be attached to a solid support if desired. For example, such attachment to solid supports can be made for use in separation and purification processes and similar applications. The extent to which multivalent binding is realized depends upon the efficiency with which the linker or linkers that joins the ligands presents these ligands to the array of available ligand binding sites. Beyond presenting these ligands for multivalent interactions with ligand binding sites, the linker or linkers spatially constrains these interactions to occur within dimensions defined by the linker or linkers. Thus, the structural feamres of the linker (valency, geometry, orientation, size, flexibility, chemical composition, etc.) are feamres of multibinding agents that play an important role in determining their activities. The linkers used in this invention are selected to allow multivalent binding of ligands to the ligand binding sites of microsomal triglyceride transferase protein, whether such sites are located interiorly, both interiorly and on the periphery of the protein structure, or at any intermediate position thereof. The ligands are covalently attached to the linker or linkers using conventional chemical techniques providing for covalent linkage of the ligand to the linker or linkers. Reaction chemistries resulting in such linkages are well known in the art and involve the use of complementary functional groups on the linker and ligand. Preferably, the complementary functional groups on the linker are selected relative to the functional groups available on the ligand for bonding or which can be introduced onto the ligand for bonding. Again, such complementary functional groups are well known in the art. For example, reaction between a carboxylic acid of either the linker or the ligand and a primary or secondary amine of the ligand or the linker in the presence of suitable, well- known activating agents results in formation of an amide bond covalently linking the ligand to the linker; reaction between an amine group of either the linker or the ligand and a sulfonyl halide of the ligand or the linker results in formation of a sulfonamide bond covalently linking the ligand to the linker; and reaction between an alcohol or phenol group of either the linker or the ligand and an alkyl or aryl halide of the ligand or the linker results in formation of an ether bond covalently linking the ligand to the linker. Table I below illustrates numerous complementary reactive groups and the resulting bonds formed by reaction there between. Table I Representative Complementary Binding Chemistries First Reactive Group Second Reactive Group Linkage hydroxyl isocyanate urethane amine epoxide b-hydroxyamine sulfonyl halide amine sulfonamide carboxyl amine amide hydroxyl alkyl/aryl halide ether The linker is attached to the ligand at a position that retains ligand domain-ligand binding site interaction and specifically which permits the ligand domain of the ligand to orient itself to bind to the ligand binding site. Such positions and synthetic protocols for linkage are well known in the art. The term linker embraces everything that is not considered to be part of the ligand. The relative orientation in which the ligand domains are displayed derives from the particular point or points of attachment of the ligands to the linker, and on the framework geometry. The determination of where acceptable substimtions can be made on a ligand is typically based on prior knowledge of structure- activity relationships (SAR) of the ligand and/or congeners and/or strucmral information about ligand-receptor complexes (e.g., X-ray crystallography, NMR, and the like). Such positions and the synthetic methods for covalent attachment are well known in the art. Following attachment to the selected linker (or attachment to a significant portion of the linker, for example 2-10 atoms of the linker), the univalent linker-ligand conjugate may be tested for retention of activity in the relevant assay. Suitable linkers are discussed more fully below. At present, it is preferred that the multibinding agent is a bivalent compound, e.g., two ligands which are covalently linked to linker X. The term "library" refers to at least 3, preferably from 10 2 to 10 9 and more preferably from 10 2 to 10 4 multimeric compounds. Preferably, these compounds are prepared as a multiplicity of compounds in a single solution or reaction mixture which permits the facile synthesis thereof. In one embodiment, the library of multimeric compounds can be directly assayed for multibinding properties. In another embodiment, each member of the library of multimeric compounds is first isolated and, optionally, characterized. This member is then assayed for multibinding properties. The term "collection" refers to a set of multimeric compounds which are prepared either sequentially or concurrently (e.g., combinatorially). The collection comprises at least 2 members; preferably from 2 to 10 9 members and still more preferably from 10 to 10 4 members. The term "pseudohalide" refers to a functional group which react in a displacement reaction in a manner similar to a halogen, e.g. , functions as a leaving group is a displacement reaction. Such functional groups include, by way of example, mesyl, tosyl, azido, cyano and the like. Methodology The linker, when covalently attached to multiple copies of the ligands, provides a biocompatible, substantially non-immunogenic multibinding compound. The biological activity of the multibinding compound is highly sensitive to the valency, geometry, composition, size, flexibility or rigidity, etc. of the linker and, in mm, on the overall structure of the multibinding compound, as well as the presence or absence of anionic or cationic charge, the relative hydrophobicity /hydrophilicity of the linker, and the like on the linker. Accordingly, the linker is preferably chosen to maximize the biological activity of the multibinding compound. The linker may be chosen to enhance the biological activity of the molecule. In general, the linker may be chosen from any organic molecule construct that orients two or more ligands to their ligand binding sites to permit multivalency. In this regard, the linker can be considered as a "framework" on which the ligands are arranged in order to bring about the desired ligand-orienting result, and thus produce a multibinding compound. For example, different orientations can be achieved by including in the framework groups containing mono- or polycyclic groups, including aryl and/or heteroaryl groups, or strucmres incorporating one or more carbon-carbon multiple bonds (alkenyl, alkenylene, alkynyl or alkynylene groups). Other groups can also include oligomers and polymers which are branched- or straight- chain species. In preferred embodiments, rigidity is imparted by the presence of cyclic groups (e.g., aryl, heteroaryl, cycloalkyl, heterocyclic, etc.). In other preferred embodiments, the ring is a six or ten member ring. In still further preferred embodiments, the ring is an aromatic ring such as, for example, phenyl or naphthyl. Different hydrophobic/hydrophilic characteristics of the linker as well as the presence or absence of charged moieties can readily be controlled by the skilled artisan. For example, the hydrophobic nature of a linker derived from hexamethylene diamine (H 2 N(CH 2 ) 6 NH 2 ) or related polyamines can be modified to be substantially more hydrophilic by replacing the alkylene group with a poly(oxyalkylene) group such as found in the commercially available "Jeffamines". The intersection of the framework (linker) and the ligand group, and indeed, the framework (linker) itself can have many different bonding patterns. Examples of acceptable patterns of three contiguous atom arrangements are shown in the following diagram: CCC NCC OCC SCC PCC CCN NCN OCN SCN PCN CCO NCO OCO SCO PCO CCS NCS OCS SCS PCS CCP NCP OCP SCP PCP CNC NNC ONC SNC PNC CNN NNN ONN SNN PNN CNO NNO ONO SNO PNO CNS NNS ONS SNS PNS CNP NNP ONP SNP PNP COC NOC OOC SOC POC CON NON OON SON PON COO NOO OOO SOO POO COS NOS OOS SOS POS COP NOP OOP SOP POP CSC NSC OSC SSC PSC CSN NSN OSN SSN PSN CSO NSO OSO SSO PSO CSS NSS OSS sss PSS CSP NSP OSP SSP PSP CPC NPC OPC SPC PPC CPN NPN OPN SPN PPN CPO NPO OPO SPO PPO CPS NPS OPS SPS PPS CPP NPP OPP SPP PPP One skilled in the art would be able to identify bonding patterns that would produce multivalent compounds. Methods for producing these bonding arrangements are described in March, "Advanced Organic Chemistry", 4th Edition, Wiley-Interscience, New York, New York (1992). All of the possible arrangements for the five most preferred atoms are shown. Each atom has a variety of acceptable oxidation states. The bonding arrangements underlined are less acceptable and are not preferred. Examples of molecular strucmres in which the above bonding patterns could be employed as components of the linker are shown below. The identification of an appropriate framework geometry and size for ligand domain presentation are important steps in the construction of a multibinding compound with enhanced activity. Systematic spatial searching strategies can be used to aid in the identification of preferred frameworks through an iterative process. FIG. 2 illustrates a useful strategy for determining an optimal framework display orientation for ligand domains. Various other strategies are known to those skilled in the art of molecular design and can be used for preparing compounds of this invention. As shown in FIG. 2, display vectors around similar central core strucmres such as a phenyl strucmre and a cyclohexane strucmre can be varied, as can the spacing of the ligand domain from the core strucmre (i.e., the length of the attaching moiety). It is to be noted that core strucmres other than those shown here can be used for determining the optimal framework display orientation of the ligands. The process may require the use of multiple copies of the same central core strucmre or combinations of different types of display cores. The above-described process can be extended to trimers (FIG. 3) and compound of higher valency. Assays of each of the individual compounds of a collection generated as described above will lead to a subset of compounds with the desired enhanced activities (e.g. , potency, selectivity, etc.). The analysis of this subset using a technique such as Ensemble Molecular Dynamics will provide a framework orientation that favors the properties desired. A wide diversity of linkers is commercially available (see, e.g., Available Chemical Directory (ACD)). Many of the linkers that are suitable for use in this invention fall into this category. Other can be readily synthesized by methods well known in the art and/or are described below. Having selected a preferred framework geometry, the physical properties of the linker can be optimized by varying the chemical composition thereof. The composition of the linker can be varied in numerous ways to achieve the desired physical properties for the multibinding compound. It can therefore be seen that there is a plethora of possibilities for the composition of a linker. Examples of linkers include aliphatic moieties, aromatic moieties, steroidal moieties, peptides, and the like. Specific examples are peptides or polyamides, hydrocarbons, aromatic groups, ethers, lipids, cationic or anionic groups, or a combination thereof. Examples are given below, but it should be understood that various changes may be made and equivalents may be substimted without departing from the true spirit and scope of the invention. For example, properties of the linker can be modified by the addition or insertion of ancillary groups into or onto the linker, for example, to change the solubility of the multibinding compound (in water, fats, lipids, biological fluids, etc.), hydrophobicity, hydrophilicity, linker flexibility, antigenicity, stability, and the like. For example, the introduction of one or more poly(ethylene glycol) (PEG) groups onto or into the linker enhances the hydrophilicity and water solubility of the multibinding compound, increases both molecular weight and molecular size and, depending on the nature of the unPEGylated linker, may increase the in vivo retention time. Further PEG may decrease antigenicity and potentially enhances the overall rigidity of the linker. Ancillary groups which enhance the water solubility/hydrophilicity of the linker and, accordingly, the resulting multibinding compounds are useful in practicing this invention. Thus, it is within the scope of the present invention to use ancillary groups such as, for example, small repeating units of ethylene glycols, alcohols, polyols (e.g., glycerin, glycerol propoxylate, saccharides, including mono-, oligosaccharides, etc.), carboxylates (e.g., small repeating units of glutamic acid, acrylic acid, etc.), amines (e.g., tetraethylenepentamine), and the like) to enhance the water solubility and/or hydrophilicity of the multibinding compounds of this invention. In preferred embodiments, the ancillary group used to improve water solubility/hydrophilicity will be a polyether . The incorporation of lipophilic ancillary groups within the strucmre of the linker to enhance the lipophilicity and/or hydrophobicity of the multibinding compounds described herein is also within the scope of this invention. Lipophilic groups useful with the linkers of this invention include, by way of example only, aryl and heteroaryl groups which, as above, may be either unsubstituted or substimted with other groups, but are at least substimted with a group which allows their covalent attachment to the linker. Other lipophilic groups useful with the linkers of this invention include fatty acid derivatives which do not form bilayers in aqueous medium until higher concentrations are reached. Also within the scope of this invention is the use of ancillary groups which result in the multibinding compound being incorporated or anchored into a vesicle or other membranous strucmre such as a liposome or a micelle. The term "lipid" refers to any fatty acid derivative that is capable of forming a bilayer or a micelle such that a hydrophobic portion of the lipid material orients toward the bilayer while a hydrophilic portion orients toward the aqueous phase. Hydrophilic characteristics derive from the presence of phosphato, carboxylic, sulfato, amino, sulfhydryl, nitro and other like groups well known in the art. Hydrophobicity could be conferred by the inclusion of groups that include, but are not limited to, long chain saturated and unsamrated aliphatic hydrocarbon groups of up to 20 carbon atoms and such groups substimted by one or more aryl, heteroaryl, cycloalkyl, and/or heterocyclic group(s). Preferred lipids are phosphglycerides and sphingolipids, representative examples of which include phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, phosphatidylinositol, phosphatidic acid, palmitoyleoyl phosphatidylcholine, ly sophosphatidylcholine , ly sophosphatidy 1-ethanolamine , dipalmitoylphosphatidylcholine, dioleoylphosphatidylcholine, distearoyl- phosphatidylcholine or dilinoleoylphosphatidylcholine could be used. Other compounds lacking phosphorus, such as sphingolipid and glycosphingolipid families are also within the group designated as lipid. Additionally, the amphipathic lipids described above may be mixed with other lipids including triglycerides and sterols. The flexibility of the linker can be manipulated by the inclusion of ancillary groups which are bulky and/or rigid. The presence of bulky or rigid groups can hinder free rotation about bonds in the linker or bonds between the linker and the ancillary group(s) or bonds between the linker and the functional groups. Rigid groups can include, for example, those groups whose conformational lability is restrained by the presence of rings and/or multiple bonds within the group, for example, aryl, heteroaryl, cycloalkyl, cycloalkenyl, and heterocyclic groups. Other groups which can impart rigidity include polypeptide groups such as oligo- or polyproline chains. Rigidity may also be imparted by internal hydrogen bonding or by hydrophobic collapse. Bulky groups can include, for example, large atoms, ions (e.g., iodine, sulfur, metal ions, etc.) or groups containing large atoms, polycyclic groups, including aromatic groups, non-aromatic groups and strucmres incorporating one or more carbon-carbon multiple bonds (i.e., alkenes and alkynes). Bulky groups can also include oligomers and polymers which are branched- or straight-chain species. Species that are branched are expected to increase the rigidity of the strucmre more per unit molecular weight gain than are straight-chain species. In preferred embodiments, rigidity is imparted by the presence of cyclic groups (e.g., aryl, heteroaryl, cycloalkyl, heterocyclic, etc.). In other preferred embodiments, the linker comprises one or more six-membered rings. In still further preferred embodiments, the ring is an aryl group such as, for example, phenyl or naphthyl. Rigidity can also be imparted electrostatically. Thus, if the ancillary groups are either positively or negatively charged, the similarly charged ancillary groups will force the presenter linker into a configuration affording the maximum distance between each of the like charges. The energetic cost of bringing the like-charged groups closer to each other will tend to hold the linker in a configuration that maintains the separation between the like-charged ancillary groups. Further ancillary groups bearing opposite charges will tend to be attracted to their oppositely charged counterparts and potentially may enter into both inter- and intramolecular ionic bonds. This non-covalent mechanism will tend to hold the linker into a conformation which allows bonding between the oppositely charged groups. The addition of ancillary groups which are charged, or alternatively, bear a latent charge when deprotected, following addition to the linker, include deprotectation of a carboxyl, hydroxyl, thiol or amino group by a change in pH, oxidation, reduction or other mechanisms known to those skilled in the art which result in removal of the protecting group, is within the scope of this invention. In view of the above, it is apparent that the appropriate selection of a linker group providing suitable orientation, restricted/unrestricted rotation, the desired degree of hydrophobicity/hydrophilicity, etc. is well within the skill of the art. Eliminating or reducing antigenicity of the multibinding compounds described herein is also within the scope of this invention. In certain cases, the antigenicity of a multibinding compound may be eliminated or reduced by use of groups such as, for example, poly (ethylene glycol). As explained above, the multibinding compounds described herein comprise 2-10 ligands attached to a linker that links the ligands in such a manner that they are presented to the target receptor for multivalent interactions with ligand binding sites thereon/ therein. The linker spatially constrains these interactions to occur within dimensions defined by the linker. This and other factors increases the biological activity of the multibinding compound as compared to the same number of ligands made available in monobinding form. The compounds of this invention are preferably represented by the empirical formula (L) p (X) q where L, X, p and q are as defined above. This is intended to include the several ways in which the ligands can be linked together in order to achieve the objective of multivalency, and a more detailed explanation is described below. As noted previously, the linker may be considered as a framework to which ligands are attached. Thus, it should be recognized that the ligands can be attached at any suitable position on this framework, for example, at the termini of a linear chain or at any intermediate position. The simplest and most preferred multibinding compound is a bivalent compound which can be represented as L-X-L, where each L is independently a ligand which may be the same or different and each X is independently the linker. Examples of such bivalent compounds are provided in FIG. 2 where each shaded circle represents a ligand. A trivalent compound could also be represented in a linear fashion, i.e., as a sequence of repeated units L-X-L-X-L, in which L is a ligand and is the same or different at each occurrence, as can X. However, a trimer can also be a radial multibinding compound comprising three ligands attached to a central core, and thus represented as (L^X, where the linker X could include, for example, an aryl or cycloalkyl group. Illustrations of trivalent and tetravalent compounds of this invention are found in FIG.s 3 and 4 respectively where, again, the shaded circles represent ligands. Tetravalent compounds can be represented in a linear array, e.g., L-X-L-X-L-X-L in a branched array, e.g., L-X-L-X-L I L (a branched construct analogous to the isomers of butane — Az-butyl, wo-butyl, sec-butyl, and t-butyl) or in a tetrahedral array, e.g., X / X where X and L are as defined herein. Alternatively, it could be represented as an alkyl, aryl or cycloalkyl derivative as above with four (4) ligands attached to the core linker. The same considerations apply to higher multibinding compounds of this invention containing 5-10 ligands as illustrated in FIG. 5 where, as before, the shaded circles represent ligands. However, for multibinding agents attached to a central linker such as aryl or cycloalkyl, there is a self-evident constraint that there must be sufficient attachment sites on the linker to accommodate the number of ligands present; for example, a benzene ring could not directly accommodate more than 6 ligands, whereas a multi-ring linker (e.g., biphenyl) could accommodate a larger number of ligands. Certain of the above described compounds may alternatively be represented as cyclic chains of the form: X X and variants thereof. All of the above variations are intended to be within the scope of the invention defined by the formula (L) p (X) q . With the foregoing in mind, a preferred linker may be represented by the following formula: -X a -Z-(Y a -Z) m -Y b -Z-X a in which: m is an integer of from 0 to 20; X a at each separate occurrence is selected from the group consisting of -O-, -S-, -NR-, -C(O)-, -C(O)O-, -C(O)NR-, -C(S), -C(S)O-, -C(S)NR- or a covalent bond where R is as defined below; Z is at each separate occurrence is selected from the group consisting of alkylene, substimted alkylene, cycloalkylene, substimted cylcoalkylene, alkenylene, substimted alkenylene, alkynylene, substituted alkynylene, cycloalkenylene, substimted cycloalkenylene, arylene, heteroarylene, heterocyclene, or a covalent bond; Y a and Y b at each separate occurrence are selected from the group consisting of: -S-S- or a covalent bond; in which: n is 0, 1 or 2; and R, R' and R" at each separate occurrence are selected from the group consisting of hydrogen, alkyl, substimted alkyl, cycloalkyl, substimted cycloalkyl, alkenyl, substimted alkenyl, cycloalkenyl, substimted cycloalkenyl, alkynyl, substimted alkynyl, aryl, heteroaryl and heterocyclic. Additionally, the linker moiety can be optionally substimted at any atom therein by one or more alkyl, substimted alkyl, cycloalkyl, substimted cycloalkyl, alkenyl, substimted alkenyl, cycloalkenyl, substimted cycloalkenyl, alkynyl, substimted alkynyl, aryl, heteroaryl and heterocyclic group.

In yet another embodiment, the linker (i.e., X or X') has the formula: -(CH 2 ) n -, where n' is an integer ranging from 1 to about 20, preferably from 2 to 6. In view of the above description of the linker, it is understood that the term "linker" when used in combination with the term "multibinding compound" includes both a covalently contiguous single linker (e.g., L-X-L) and multiple covalently non-contiguous linkers (L-X-L-X-L) within the multibinding compound. Preparation of Multibinding Compounds The multibinding compounds of this invention can be prepared from readily available starting materials using the following general methods and procedures. It will be appreciated that where typical or preferred process conditions (i.e., reaction temperatures, times, mole ratios of reactants, solvents, pressures, etc.) are given, other process conditions can also be used unless otherwise stated. Optimum reaction conditions may vary with the particular reactants or solvent used, but such conditions can be determined by one skilled in the art by routine optimization procedures. Additionally, as will be apparent to those skilled in the art, conventional protecting groups may be necessary to prevent certain functional groups from undergoing undesired reactions. The choice of a suitable protecting group for a particular functional group as well as suitable conditions for protection and deprotection are well known in the art. For example, numerous protecting groups, and their introduction and removal, are described in T. W. Greene and G. M. Wuts, Protecting Groups in Organic Synthesis, Second Edition, Wiley, New York, 1991, and references cited therein. Any compound which inhibits or binds to microsomal triglyceride transferase protein can be used as a ligand in this invention. As discussed in further detail below, numerous such compounds are known in the art and any of these known compounds or derivatives thereof may be employed as ligands in this invention. Typically, a compound selected for use as a ligand will have at least one functional group, such as an amino, amido, hydroxyl, thiol or carboxyl group and the like, which allows the compound to be readily coupled to the linker. Compounds having such functionality are either known in the art or can be prepared by routine modification of known compounds using conventional reagents and procedures. The patents and publications set forth below provide numerous examples of suitably functionalized compounds with inhibit or bind to microsomal triglyceride transferase protein and intermediates thereof which may be used as ligands in this invention. The ligand can be covalently attached to the linker through any available position on the ligand, provided that when the ligand is attached to the linker, the ligand retains its ability to inhibit or bind to microsomal triglyceride transferase protein. A preferred group of ligands for use in this invention are those ligands having formulae IA-IE. A more preferred group of ligands are those having formulae IIA-IIE. Examples of multibinding compounds of this invention having specific ligands are illustrated in Figures 6-8, wherein —represents the linker. Ligands of formula IA-IE and IIA-IIE are either known in the art or can be readily prepared using art-recognized starting materials, reagents and reaction conditions. By way of illustration, the following patents and publications disclose compounds, intermediates and procedures useful in the preparation of ligands of formulae IA-IE and IIA-IIE or related compounds suitable for use in this invention: U.S. Patent No. 5,712,279, issued January 27, 1998 to Biller et al.; U.S. Patent No. 5,739,135, issued April 14, 1998 to Biller et al.; U.S. Patent No. 5,760,246, issued June 2, 1998 to Biller et al.; U.S. Patent No. 5,827,875, issued October 27, 1998 to Dickson Jr. et al.; U.S. Statutory Invention Registration No. H1729, published May 5, 1998 by Biller et al. ; WO 96/40640, published December 19, 1996; WO 97/26240, published July 24, 1997; WO 97/43255, published November 20, 1997; WO 98/03069, published January 29, 1998; WO 98/03174, published January 29, 1998; WO 98/23593, published June 4, 1998; WO 98/27979, published July 2, 1998; WO 98/31225, published July 23, 1998; WO 98/31366, published July 23, 1998; WO 98/31367, published July 23, 1998; and EP 0 643 057 Al, published March 15, 1995. Each of these patents and publications is incorporated herein by reference in its entirety to the same extent as if each individual patent or publication was specifically and individually indicated to be incorporated by reference in its entirety. The syntheses of specific ligands or ligand precusors (i.e., Synthons A-I) are described in further detail in the Examples set forth below. The compounds of formula I are typically prepared by coupling two or more ligands to a linker using conventional coupling procedures. Such coupling reactions are typically conducted by reacting to complimentary functional groups, such as carboxylic acid and an amine, to form a stable covalent bond, e.g. an amide. Suitable complimentary functional groups are described herein above. By way of example, two or more ligands containing a carboxylic acid functional group can be coupled with a polyamine to form a polyamide as illustrated in Scheme 1 (where for purposes of illustration, R represents the ligand and R' represents the linking group). Scheme 1 Typically, this reaction is conducted by first activating the carboxylic acid, i.e., by conversion to a carboxylic acid anhydride or acid halide, and then coupling the activated carboxylic acid with a polyamine. For example, a carboxylic acid may be converted into a mixed trifluoroacetic anhydride by contacting the carboxylic acid with one molar equivalent of trifluoroacetic anhydride in an inert diluent, such as THF, at ambient temperamre for about 0.5 to 6 hours. The resulting mixed anhydride intermediate is typically not isolated, but is contacted in situ with a polyamine having one molar equivalent of amine groups. This reaction is typically conducted in an inert diluent, such as THF, at a temperamre ranging from about 0°C to about 100°C for about 1 to 48 hours. Upon completion of the reaction, the compound of formula I is typically isolated and purified using conventional techniques, extraction, precipitation, chromatography, filtration, and the like. Additionally, if desired, the carboxylic acid can be converted into an acid halide and the acid halide coupled with a polyamine to provide compounds of formula I. Acid halides can be prepared by contacting the carboxylic acid with an inorganic acid halide, such as thionyl chloride, phosphorous trichloride, phosphorous tribromide or phosphorous penta-chloride, or preferably, with oxalyl chloride under conventional conditions. Generally, this reaction is conducted using about 1 to 5 molar equivalents of the inorganic acid halide or oxalyl chloride, either neat or in an inert solvent, such as dichloromethane or carbon tetrachloride, at temperamre in the range of about 0°C to about 80 °C for about 1 to about 48 hours. A catalyst, such as DMF, may also be used in this reaction. The acid halide is then contacted with a polyamine containing one molar equivalent of amino groups in an inert diluent, such as dichloromethane, at a temperamre ranging from about -70 °C to about 40 °C for about 1 to about 24 hours. Preferably, this reaction is conducted in the presence of a suitable base to scavenge the acid generated during the reaction. Suitable bases include, by way of example, tertiary amines, such as triethylamine, diisopropylethylamine, N- methylmorpholme and the like. Alternatively, the reaction can be conducted under Schotten-Baumann-type conditions using aqueous alkali, such as sodium hydroxide and the like. Upon completion of the reaction, the compound of formula I is recovered by conventional methods including neutralization, extraction, precipitation, chromatography, filtration, and the like. Alternatively, the carboxylic acid may be directed coupled with the polyamine using well-known coupling reagents such as carbodiimides, BOP reagent (benzotriazol- 1 -yloxy-tris(dimethylamino)phosphonium hexafluorophosphonate) and the like. Suitable carbodiimides include, by way of example, dicyclohexylcarbodiimide (DCC), l-(3-dimethylamino-propyl)-3- ethylcarbodiimide (EDC) and the like. If desired, polymer supported forms of carbodiimide coupling reagents may also be used including, for example, those described in Tetrahedron Letters, 34(48), 7685 (1993). Additionally, well-known coupling promoters, such as Ν-hydroxysuccinimide, 1-hydroxybenzotriazole and the like, may be used to facilitate the coupling reaction. This coupling reaction is typically conducted by contacting the carboxylic acid with about 1 to about 2 equivalents of the coupling reagent and with a polyamine containing one molar equivalent of amino groups in an inert diluent, such as dichloromethane, chloroform, acetonitrile, tetrahydrofuran, N,N- dimethylformamide and the like. Generally, this reaction is conducted at a temperamre ranging from about 0°C to about 37°C for about 12 to about 24 hours. Upon completion of the reaction, the compound of formula I is recovered by conventional methods including neutralization, extraction, precipitation, chromatography, filtration, and the like. Compounds of formula I can also be prepared by reacting two or more ligands containing a primary or secondary amine functional group with an alkyl poly(halide) to form a polyamine as shown in Scheme 2 (where for purposes of illustration, R represents a portion of the ligand or hydrogen and R' represents the linking group). Scheme 2 This coupling reaction is typically conducted by contacting the amine compound with a suitable alkali or alkaline earth metal base, such as potassium carbonate, in an inert diluent, such as DMF and the like, in the presence of a alkyl poly (halide) having one molar equivalent halide groups. Generally, this reaction is conducted at a temperamre ranging from about 25 °C to about 100°C for about 24 to about 72 hours. Optionally, a catalytic amount of sodium or potassium iodide may be added to the reaction mixture when an alkyl poly(chloride) or poly(bromide) is employed in the reaction. Upon completion of the reaction, the compound of formula I is recovered by conventional methods including neutralization, extraction, precipitation, chromatography, filtration, and the like. Other methods and reaction conditions for preparing compounds of formula I are described in further detail in the Examples set forth below. As will be readily apparent to those of ordinary skill in the art, the synthetic procedures described herein or those known in the art may be readily modified to afford a wide variety of compounds within the scope of this invention. Combinatorial Libraries The methods described herein lend themselves to combinatorial approaches for identifying multimeric compounds which possess multibinding properties. Specifically, factors such as the proper juxtaposition of the individual ligands of a multibinding compound with respect to the relevant array of binding sites on a target or targets is important in optimizing the interaction of the multibinding compound with its target(s) and to maximize the biological advantage through multivalency. One approach is to identify a library of candidate multibinding compounds with properties spanning the multibinding parameters that are relevant for a particular target. These parameters include: (1) the identity of ligand(s), (2) the orientation of ligands, (3) the valency of the construct, (4) linker length, (5) linker geometry, (6) linker physical properties, and (7) linker chemical functional groups. Libraries of multimeric compounds potentially possessing multibinding properties (i.e. , candidate multibinding compounds) and comprising a multiplicity of such variables are prepared and these libraries are then evaluated via conventional assays corresponding to the ligand selected and the multibinding parameters desired. Considerations relevant to each of these variables are set forth below: Selection of Ligand(s) A single ligand or set of ligands is (are) selected for incorporation into the libraries of candidate multibinding compounds which library is directed against a particular biological target or targets, i.e., inhibition of MTP. The only requirement for the ligands chosen is that they are capable of interacting with the selected target(s). Thus, ligands may be known drugs, modified forms of known drugs, substructures of known drugs or substrates of modified forms of known drugs (which are competent to interact with the target), or other compounds. Ligands are preferably chosen based on known favorable properties that may be projected to be carried over to or amplified in multibinding forms. Favorable properties include demonstrated safety and efficacy in human patients, appropriate PK/ADME profiles, synthetic accessibility, and desirable physical properties such as solubility, logP, etc. However, it is crucial to note that ligands which display an unfavorable property from among the previous list may obtain a more favorable property through the process of multibinding compound formation; i.e., ligands should not necessarily be excluded on such a basis. For example, a ligand that is not sufficiently potent at a particular target so as to be efficacious in a human patient may become highly potent and efficacious when presented in multibinding form. A ligand that is potent and efficacious but not of utility because of a non-mechanism-related toxic side effect may have increased therapeutic index (increased potency relative to toxicity) as a multibinding compound. Compounds that exhibit short in vivo half-lives may have extended half-lives as multibinding compounds. Physical properties of ligands that limit their usefulness (e.g. poor bioavailability due to low solubility, hydrophobicity, hydrophilicity) may be rationally modulated in multibinding forms, providing compounds with physical properties consistent with the desired utility. Orientation: Selection of Ligand Attachment Points and Linking Chemistry Several points are chosen on each ligand at which to attach the ligand to the linker. The selected points on the ligand/linker for attachment are mnctionalized to contain complementary reactive functional groups. This permits probing the effects of presenting the ligands to their target binding site(s) in multiple relative orientations, an important multibinding design parameter. The only requirement for choosing attachment points is that attaching to at least one of these points does not abrogate activity of the ligand. Such points for attachment can be identified by strucmral information when available. For example, inspection of a co-crystal strucmre of a ligand bound to its target allows one to identify one or more sites where linker attachment will not preclude the ligand/target interaction. Alternatively, evaluation of ligand/target binding by nuclear magnetic resonance will permit the identification of sites non-essential for ligand/target binding. See, for example, Fesik, et al., U.S. Patent No. 5,891,643, the disclosure of which is incorporated herein by reference in its entirety. When such strucmral information is not available, utilization of structure-activity relationships (SAR) for ligands will suggest positions where substantial strucmral variations are and are not allowed. In the absence of both strucmral and SAR information, a library is merely selected with multiple points of attachment to allow presentation of the ligand in multiple distinct orientations. Subsequent evaluation of this library will indicate what positions are suitable for attachment. It is important to emphasize that positions of attachment that do abrogate the activity of the monomeric ligand may also be advantageously included in candidate multibinding compounds in the library provided that such compounds bear at least one ligand attached in a manner which does not abrogate intrinsic activity. This selection derives from, for example, heterobivalent interactions within the context of a single target molecule. For example, consider a ligand bound to its target, and then consider modifying this ligand by attaching to it a second copy of the same ligand with a linker which allows the second ligand to interact with the same target at sites proximal to the first binding site, which include elements of the target that are not part of the formal ligand binding site and/or elements of the matrix surrounding the formal binding site, such as the membrane. Here, the most favorable orientation for interaction of the second ligand molecule may be achieved by attaching it to the linker at a position which abrogates activity of the ligand at the first binding site. Another way to consider this is that the SAR of individual ligands within the context of a multibinding strucmre is often different from the SAR of those same ligands in momomeric form. The foregoing discussion focused on bivalent interactions of dimeric compounds bearing two copies of the same ligand joined to a single linker through different attachment points, one of which may abrogate the binding/activity of the monomeric ligand. It should also be understood that bivalent advantage may also be attained with heterodimeric constructs bearing two different ligands that bind to common or different targets. Once the ligand attachment points have been chosen, one identifies the types of chemical linkages that are possible at those points. The most preferred types of chemical linkages are those that are compatible with the overall strucmre of the ligand (or protected forms of the ligand) readily and generally formed, stable and intrinsically innocuous under typical chemical and physiological conditions, and compatible with a large number of available linkers. Amide bonds, ethers, amines, carbamates, ureas, and sulfonamides are but a few examples of preferred linkages. Linker Selection In the library of linkers employed to generate the library of candidate multibinding compounds, the selection of linkers employed in this library of linkers takes into consideration the following factors: Valency: In most instances the library of linkers is initiated with divalent linkers. The choice of ligands and proper juxtaposition of two ligands relative to their binding sites permits such molecules to exhibit target binding affinities and specificities more than sufficient to confer biological advantage. Furthermore, divalent linkers or constructs are also typically of modest size such that they retain the desirable biodistribution properties of small molecules. Linker Length: Linkers are chosen in a range of lengths to allow the spanning of a range of inter-ligand distances that encompass the distance preferable for a given divalent interaction. In some instances the preferred distance can be estimated rather precisely from high-resolution strucmral information of targets. In other instances where high-resolution strucmral information is not available, one can make use of simple models to estimate the maximum distance between binding sites either on adjacent receptors or at different locations on the same receptor. In simations where two binding sites are present on the same target (or target subunit for multisubunit targets), preferred linker distances are 2-20 Λ, with more preferred linker distances of 3-12 A. In simations where two binding sites reside on separate target sites, preferred linker distances are 20-100 A, with more preferred distances of 30-70 A. Linker Geometry and Rigidity: The combination of ligand attachment site, linker length, linker geometry, and linker rigidity determine the possible ways in which the ligands of candidate multibinding compounds may be displayed in three dimensions and thereby presented to their binding sites. Linker geometry and rigidity are nominally determined by chemical composition and bonding pattern, which may be controlled and are systematically varied as another spanning function in a multibinding array. For example, linker geometry is varied by attaching two ligands to the ortho, meta, and para positions of a benzene ring, or in cis- or trans-arrangements at the 1,1- vs. 1,2- vs. 1,3- vs. 1 ,4- positions around a cyclohexane core or in cis- or tratzs -arrangements at a point of ethylene unsamration. Linker rigidity is varied by controlling the number and relative energies of different conformational states possible for the linker. For example, a divalent compound bearing two ligands joined by 1,8- octyl linker has many more degrees of freedom, and is therefore less rigid than a compound in which the two ligands are attached to the 4,4' positions of a biphenyl linker. Linker Physical Properties: The physical properties of linkers are nominally determined by the chemical constitution and bonding patterns of the linker, and linker physical properties impact the overall physical properties of the candidate multibinding compounds in which they are included. A range of linker compositions is typically selected to provide a range of physical properties (hydrophobicity, hydrophilicity, amphiphilicity, polarization, acidity, and basicity) in the candidate multibinding compounds. The particular choice of linker physical properties is made within the context of the physical properties of the ligands they join and preferably the goal is to generate molecules with favorable PK ADME properties. For example, linkers can be selected to avoid those that are too hydrophilic or too hydrophobic to be readily absorbed and/or distributed in vivo. Linker Chemical Functional Groups: Linker chemical functional groups are selected to be compatible with the chemistry chosen to connect linkers to the ligands and to impart the range of physical properties sufficient to span initial examination of this parameter. Combinatorial Synthesis Having chosen a set of n ligands (n being determined by the sum of the number of different attachment points for each ligand chosen) and m linkers by the process outlined above, a library of (n\)m candidate divalent multibinding compounds is prepared which spans the relevant multibinding design parameters for a particular target. For example, an array generated from two ligands, one which has two attachment points (Al , A2) and one which has three attachment points (BI, B2, B3) joined in all possible combinations provide for at least 15 possible combinations of multibinding compounds: Al-Al A1-A2 Al-Bl A1-B2 A1-B3 A2-A2 A2-B1 A2-B2 A2-B3 Bl-Bl B1-B2 B1-B3 B2-B2 B2-B3 B3-B3 When each of these combinations is joined by 10 different linkers, a library of 150 candidate multibinding compounds results. Given the combinatorial nature of the library, common chemistries are preferably used to join the reactive functionalies on the ligands with complementary reactive functionalities on the linkers. The library therefore lends itself to efficient parallel synthetic methods. The combinatorial library can employ solid phase chemistries well known in the art wherein the ligand and/or linker is attached to a solid support. Alternatively and preferably, the combinatorial libary is prepared in the solution phase. After synthesis, candidate multibinding compounds are optionally purified before assaying for activity by, for example, chromatographic methods (e.g., HPLC). Analysis of the Library Various methods are used to characterize the properties and activities of the candidate multibinding compounds in the library to determine which compounds possess multibinding properties. Physical constants such as solubility under various solvent conditions and logD/clogD values are determined. A combination of NMR spectroscopy and computational methods is used to determine low-energy conformations of the candidate multibinding compounds in fluid media. The ability of the members of the library to bind to the desired target and other targets is determined by various standard methods, which include radioligand displacement assays for receptor and ion channel targets, and kinetic inhibition analysis for many enzyme targets. In vitro efficacy, such as for receptor agonists and antagonists, ion channel blockers, and antimicrobial activity, are also determined. Pharmacological data, including oral absorption, everted gut penetration, other pharmacokinetic parameters and efficacy data are determined in appropriate models. In this way, key structure-activity relationships are obtained for multibinding design parameters which are then used to direct future work. The members of the library which exhibit multibinding properties, as defined herein, can be readily determined by conventional methods. First those members which exhibit multibinding properties are identified by conventional methods as described above including conventional assays (both in vitro and in vivo). Second, ascertaining the strucmre of those compounds which exhibit multibinding properties can be accomplished via art recognized procedures. For example, each member of the library can be encrypted or tagged with appropriate information allowing determination of the strucmre of relevant members at a later time. See, for example, Dower, et al., International Patent Application Publication No. WO 93/06121; Brenner, et al., Proc. Natl. Acad. Sci., USA, 89:5181 (1992); Gallop, et al., U.S. Patent No. 5,846,839; each of which are incorporated herein by reference in its entirety. Alternatively, the strucmre of relevant multivalent compounds can also be determined from soluble and untagged libaries of candidate multivalent compounds by methods known in the art such as those described by Hindsgaul, et al., Canadian Patent Application No. 2,240,325 which was published on July 11, 1998. Such methods couple frontal affinity chromatography with mass spectroscopy to determine both the strucmre and relative binding affinities of candidate multibinding compounds to receptors. The process set forth above for dimeric candidate multibinding compounds can, of course, be extended to trimeric candidate compounds and higher analogs thereof. Follow-up Synthesis and Analysis of Additional Libraries Based on the information obtained through analysis of the initial library, an optional component of the process is to ascertain one or more promising multibinding "lead" compounds as defined by particular relative ligand orientations, linker lengths, linker geometries, etc. Additional libraries can then be generated around these leads to provide for further information regarding strucmre to activity relationships. These arrays typically bear more focused variations in linker strucmre in an effort to further optimize target affinity and/or activity at the target (antagonism, partial agonism, etc.), and/or alter physical properties. By iterative redesign/analysis using the novel principles of multibinding design along with classical medicinal chemistry, biochemistry, and pharmacology approaches, one is able to prepare and identify optimal multibinding compounds that exhibit biological advantage towards their targets and as therapeutic agents. To further elaborate upon this procedure, suitable divalent linkers include, by way of example only, those derived from dicarboxylic acids, disulfonylhalides, dialdehydes, diketones, dihalides, diisocyanates, diamines, diols, mixtures of carboxylic acids, sulfonylhalides, aldehydes, ketones, halides, isocyanates, amines and diols. In each case, the carboxylic acid, sulfonylhalide, aldehyde, ketone, halide, isocyanate, amine and diol functional group is reacted with a complementary functionality on the ligand to form a covalent linkage. Such complementary functionality is well known in the art as illustrated in the following table: Representative Complementary Binding Chemisties First Reactive Group Second Reactive Group Linkage hydroxyl isocyanate carbamate amine epoxide β-hydroxyamine sulfonyl halide amine sulfonamide carboxyl acid amine amide hydroxyl alkyl/aryl halide ether aldehyde amine(+ reducing agent) amine ketone amine(+ reducing agent) amine amine isocyanate urea Exemplary linkers include the following linkers identified as X-1 through 18 as set forth below: Representative ligands for use in this invention include, by way of example, ligands of formula IA-IE and IIA-IIE as defined herein.

Pharmaceutical Formulations When employed as pharmaceuticals, the compounds of this invention are usually administered in the form of pharmaceutical compositions. These compounds can be administered by a variety of routes including oral, rectal, transdermal, subcutaneous, intravenous, intramuscular, and intranasal. These compounds are effective as both injectable and oral compositions. Such compositions are prepared in a manner well known in the pharmaceutical art and comprise at least one active compound. This invention also includes pharmaceutical compositions which contain, as the active ingredient, one or more of the compounds described herein associated with pharmaceutically acceptable carriers. In making the compositions of this invention, the active ingredient is usually mixed with an excipient, diluted by an excipient or enclosed within such a carrier which can be in the form of a capsule, sachet, paper or other container. When the excipient serves as a diluent, it can be a solid, semi-solid, or liquid material, which acts as a vehicle, carrier or medium for the active ingredient. Thus, the compositions can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), ointments containing, for example, up to 10% by weight of the active compound, soft and hard gelatin capsules, suppositories, sterile injectable solutions, and sterile packaged powders. In preparing a formulation, it may be necessary to mill the active compound to provide the appropriate particle size prior to combining with the other ingredients. If the active compound is substantially insoluble, it ordinarily is milled to a particle size of less than 200 mesh. If the active compound is substantially water soluble, the particle size is normally adjusted by milling to provide a substantially uniform distribution in the formulation, e.g. about 40 mesh. Some examples of suitable excipients include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, sterile water, syrup, and methyl cellulose. The formulations can additionally include: lubricating agents such as talc, magnesium stearate, and mineral oil; wetting agents; emulsifying and suspending agents; preserving agents such as methyl- and propylhydroxy-benzoates; sweetening agents; and flavoring agents. The compositions of the invention can be formulated so as to provide quick, sustained or delayed release of the active ingredient after administration to the patient by employing procedures known in the art. The compositions are preferably formulated in a unit dosage form, each dosage containing from about 0.001 to about 1 g, more usually about 1 to about 30 mg, of the active ingredient. The term "unit dosage forms" refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient. Preferably, the compound of formula I above is employed at no more than about 20 weight percent of the pharmaceutical composition, more preferably no more than about 15 weight percent, with the balance being pharmaceutically inert carrier(s). The active compound is effective over a wide dosage range and is generally administered in a pharmaceutically effective amount. It, will be understood, however, that the amount of the compound acmally administered will be determined by a physician, in the light of the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered and its relative activity, the age, weight, and response of the individual patient, the severity of the patient's symptoms, and the like. For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a compound of the present invention. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules. This solid preformulation is then subdivided into unit dosage forms of the type described above containing from, for example, 0.1 to about 500 mg of the active ingredient of the present invention. The tablets or pills of the present invention may be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol, and cellulose acetate. The liquid forms in which the novel compositions of the present invention may be incorporated for administration orally or by injection include aqueous solutions, suitably flavored syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as corn oil, cottonseed oil, sesame oil, coconut oil, or peanut oil, as well as elixirs and similar pharmaceutical vehicles. Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described supra. Preferably the compositions are administered by the oral or nasal respiratory route for local or systemic effect. Compositions in preferably pharmaceutically acceptable solvents may be nebulized by use of inert gases. Nebulized solutions may be inhaled directly from the nebulizing device or the nebulizing device may be attached to a face mask tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions may be administered, preferably orally or nasally, from devices which deliver the formulation in an appropriate manner.

Another preferred formulation employed in the methods of the present invention employs transdermal delivery devices ("patches"). Such transdermal patches may be used to provide continuous or discontinuous infusion of the compounds of the present invention in controlled amounts. The construction and use of transdermal patches for the delivery of pharmaceutical agents is well known in the art. See, e.g. , U.S. Patent 5,023,252, issued June 11, 1991, herein incorporated by reference in its entirety. Such patches may be constructed for continuous, pulsatile, or on demand delivery of pharmaceutical agents. Other suitable formulations for use in the present invention can be found in Remington's Pharmaceutical Sciences, Mace Publishing Company, Philadelphia, PA, 17th ed. (1985). Utility The multibinding compounds of this invention inhibit microsomal triglyceride transferase protein (MTP), a protein which mediates the transfer of lipids during the assembly of lipoproteins and related biomolecules. Accordingly, the multibinding compounds and pharmaceutical compositions of this invention are useful for lowering serum lipid, cholesterol and/or triglyceride levels, and for preventing and treating disorders associated with atherosclerosis, hyperlipemia, hyperlipidemia, hyperlipoproteinemia, hypercholestrolemia, hypertriglyceridemia, pancreatitis, diabetes and/or obsesity and the like. When used in treating or ameliorating such conditions, the compounds of this invention are typically delivered to a patient in need of such treatment by a pharmaceutical composition comprising a pharmaceutically acceptable diluent and an effective amount of at least one compound of this invention. The amount of compound administered to the patient will vary depending upon what compound and/or composition is being administered, the purpose of the administration, such as prophylaxis or therapy, the state of the patient, the manner of administration, and the like. In therapeutic applications, compositions are administered to a patient already suffering from, for example, hypertriglyceridemia or hypercholestrolemia in an amount sufficient to at least partially reduce the patient's triglyceride or cholesterol levels. Amounts effective for this use will depend on the judgment of the attending clinician depending upon factors such as the degree or severity of the disorder in the patient, the age, weight and general condition of the patient, and the like. The pharmaceutical compositions of this invention may contain more than one compound of the present invention. As noted above, the compounds administered to a patient are in the form of pharmaceutical compositions described above which can be administered by a variety of routes including oral, rectal, transdermal, subcutaneous, intravenous, intramuscular, etc.. These compounds are effective as both injectable and oral deliverable pharmaceutical compositions. Such compositions are prepared in a manner well known in the pharmaceutical art and comprise at least one active compound. The multibinding compounds of this invention can also be administered in the form of pro-drugs, i.e., as derivatives which are converted into a biologically active compound in vivo. Such pro-drugs will typically include compounds in which, for example, a carboxylic acid group, a hydroxyl group or a thiol group is converted to a biologically liable group, such as an ester, lactone or thioester group which will hydrolyze in vivo to reinstate the respective group. The following synthetic and biological examples are offered to illustrate this invention and are not to be construed in any way as limiting the scope of this invention. Unless otherwise stated, all temperatures are in degrees Celsius. EXAMPLES In the examples below, the following abbreviations have the following meanings.

A solution of Synthon F hydrochloride (18.0 g, 49 mmol) in 100 mL dimethylformamide is stirred under argon at room temperamre and treated with potassium carbonate (12.6 g, 49 mmol) followed by [l-bromobutyl]-9H-fluorene-9-carboxylic acid (16.9 g, 49 mmol). The reaction is heated to 50°C for 24 h. After cooling, the reaction is filtered to remove potassium carbonate, and the filter cake is rinsed with ethyl acetate. The solvents are removed in vacuo to afford a solid from which Synthon A is obtained as an off- white solid after recrystallization from ethanol (24.1 g, 38.7 mmol, 79%). Example B Preparation of Synthon B Synthon B is prepared from [l-bromobutyl]-N-(2,2,2-trifluoroethyl)-9H- fluorene-9-carboxamide (Example 11 in U.S. Patent No. 5,712,279), 1,3- diaminopropane, and commercially available Synthon G. The acid chloride derivative of Synthon G is generated as described in Example 10 of U.S. Patent No. 5,712,279. To a slurry of Synthon G (50.0 g, 190 mmol) in 500 mL methylene chloride is added oxalyl chloride (28.7 mL, 330 mmol) followed by five drops of dimethylformamide. The reaction bubbles vigorously and is stirred at room temperamre under argon for 2 h. At this time all solid has dissolved and gas evolution has ceased. The solvent is removed in vacuo, and the residue is dissolved in 400 mL methylene chloride. This solution is then added dropwise to a solution of 1,3-diaminopropane (31.7 mL, 380 mmol) and triethylamine (65.4 mL, 470 mmol) in 300 mL methylene chloride cooled in an ice/brine bath. After the addition is complete, a lot of solid has precipitated from the reaction. Additional methylene chloride (200 mL) is added and the reaction is stirred at room temperamre under argon for 18 h. The reaction is then diluted with 600 mL methylene chloride and washed twice with samrated sodium bicarbonate solution, once with brine, and once with IN potassium hydroxide. The organic layer is dried over sodium sulfate, and the solvent is removed in vacuo to give a white solid. This solid is recrystallized from hot ethanol and washed with heptane to afford 3"-(aminopropyl)-4'- (trifluoromethyl)-2-biphenylcarboxamide (45.8 g, 142 mmol, 75%) as a white solid. To a stirred solution of [l-bromobutyl]-N-(2,2,2-trifluoroethyl)-9H- fluorene-9-carboxamide (29.5 g, 69.2 mmol) in 100 mL dimethylformamide under argon is added anhydrous potassium carbonate (9.55 g, 69.2 mmol) followed by 3"-(aminopropyl)-4'-(trifluoromethyl)-2-biphenylcarboxamide (22.3 g, 69.2 mmol). The reaction mixmre is then heated to 50°C and stirred under argon for 24 h. After cooling, the reaction is filterred to remove potassium carbonate, and the filter cake is rinsed with ethyl acetate. The filtrate is partitioned between 20% heptane in ethyl acetate and water. The organic layer is washed five times with water and once with brine. The organic layer is then dried over sodium sulfate and the solvent is removed in vacuo to give a beige solid. This solid is recrystallized from 300 mL 25% ethyl acetate in heptane to provide Synthon B as an off-white solid ( 36.5 g, 54.7 mmol, 79%). Example C Preparation of Synthon C Synthon C is prepared from [ 1-bromobutyl] -N-(2, 2, 2-trifluoroethyl)-9H- fluorene-9-carboxamide (Example 11 in U.S. Patent No. 5,712,279), tert-butyl N-(2-aminoethyl)carbamate, l-benzyl-4-piperidone, and commercially available Synthon G. Potassium hydroxide pellets (16 g, 0.25 mole) are added to a stirred solution of tert-butyl N-(2-aminoethyl)carbamate (160 g, 1.00 mole) in 1 L of methanol. Once the pellets are completely dissolved, l-benzyl-4-piperidone (185 mL, 1.00 mole) is added in one portion and the resulting suspension is stirred under reflux for 1 h. The reaction is then cooled in an ice bath and treated dropwise with sodium cyanoborohydride (22.0 g, 0.35 mole) in 250 mL methanol. This mixture is allowed to warm to room temperamre and is then refluxed for 1 h. After cooling to room temperamre, the mixture is treated with potassium hydroxide pellets (60 g, 1.5 mole) and stirred until the pellets are completely dissolved. The reaction mixmre is suction filtered and then concentrated to 250 mL on a rotary evaporator. The residue is then diluted with 500 mL half-saturated brine and extracted with two 500 mL portions of diethyl ether. The combined organic layers are in mm extracted with two 500 mL portions of 2 Ν sodium hydrogen sulfate and then discarded. The combined aqueous extracts are adjusted to pH 10 by the addition of 6 M sodium hydroxide and then back-extracted with two 500 mL portions of ethyl acetate. The combined ethyl acetate extracts are extracted with 500 mL brine, dried over sodium sulfate, and dried to afford the crude l-benzyl-4-[(2- aminoethylcarbamato)amino]-piperidine as an oil. The acid chloride derivative of Synthon G is generated as described in Example 10 of U.S. Patent No. 5,712,279. To a slurry of Synthon G (50.0 g, 190 mmol) in 500 mL methylene chloride is added oxalyl chloride (28.7 mL, 330 mmol) followed by five drops of dimethylformamide. The reaction bubbles vigorously and is stirred at room temperamre under argon for 2 h. At this time all solid has dissolved and gas evolution has ceased. The solvent is removed in vacuo, and the residue is dissolved in 400 mL methylene chloride. This solution is then added dropwise to a solution of the crude l-benzyl-4-[(2- aminoethylcarbamato)amino]-piperidine (63.3 g, 190 mmol) prepared in the previous step and triethylamine (65.4 mL, 470 mmol) in 300 mL methylene chloride cooled in an ice/brine bath. After the addition is complete, a lot of solid has precipitated from the reaction. Additional methylene chloride (200 mL) is added and the reaction is stirred at room temperamre under argon for 18 h. The reaction is then diluted with 600 mL methylene chloride and washed twice with samrated sodium bicarbonate solution, once with brine, and once with IN potassium hydroxide. The organic layer is dried over sodium sulfate, and the solvent is removed in vacuo to give a white solid. This solid is recrystallized from hot ethanol and washed with heptane to afford l-benzyl-4-[[4'- (trifluoromethyl)[l , 1 '-biphenyl]-2-yl]carbonyl](2-aminoethylcarbamato)amino]- piperidine (74.8 g, 142 mmol, 75%) as a white solid. A solution of l-benzyl-4-[[4'-(trifluoromethyl)[l, -biphenyl]-2- yl]carbonyl](2-aminoethylcarbamato)amino]-piperidine (52.5 g, 100 mmol) in a mixmre of 200 mL ethanol plus 10 mL glacial acetic acid is treated with 10% palladium on activated carbon (2.6 g) and then subjected to hydrogenation on a Parr apparams (initial pressure 40 psi) for 19 h. The reaction is then filtered through Celite and the filtrate is concentrated to dryness. The residue is dissolved in 500 mL chloroform and washed once with 100 mL 1 N potassium hydroxide and three times with 100 mL brine. The aqueous layers are combined and back-exctracted with three 80 mL portions of chloroform. The combined organic extracts are then dried over sodium sulfate and evaporated to afford 4- [[4'-(trifluoromethyl)[l , 1 '-biphenyl]-2-yl]carbonyl](2- aminoethylcarbamato)amino]-l -piperidine (39.2 g, 90 mmol, 90%) as a white solid. To a stirred solution of [l-bromobutyl]-N-(2,2,2-trifluoroethyl)-9H- fluorene-9-carboxamide (29.5 g, 69.2 mmol) in 100 mL dimethylformamide under argon is added anhydrous potassium carbonate (9.55 g, 69.2 mmol) followed by 4-[[4'-(trifluoromethyl)[l , l'-biphenyl]-2-yl]carbonyl](2- aminoethylcarbamato)amino]-l -piperidine prepared in the previous step (30.1 g, 69.2 mmol). The reaction mixmre is then heated to 50 °C and stirred under argon for 24 h. After cooling, the reaction is filterred to remove potassium carbonate, and the filter cake is rinsed with ethyl acetate. The filtrate is partitioned between 20% heptane in ethyl acetate and water. The organic layer is washed five times with water and once with brine. The organic layer is then dried over sodium sulfate and the solvent is removed in vacuo to give a beige solid. This solid is recrystallized from 300 mL 25% ethyl acetate in heptane to provide 9-[4-[4-[[[4'-(trifluoromefhyl)[l , l'-biphenyl]-2-yl]carbonyl](2- aminoethylcarbamato)amino]-l-piperidinyl]butyl]-N-(2,2,2-trifluoroethyl)-9H- fluorene-9-carboxamide, the Boc-protected form of Synthon C (40.5 g, 52 mmol, 75%) as a white solid.

The reaction was stirred at room temperamre for 4 h, then concentrated in vacuo to afford 9-[4-[4- [[[4'-(trifluoromefhyl)[l , 1 '-biphenyl]-2-yl]carbonyl]amino]-l-piperidinyl]butyl]- N-(2,2,2-trifluoroethyl)-9H-fluorene-9-carboxamide (27.8 g, 37 mmol, 96%)) as the white solid dihydrochloride. Example D Preparation of Synthon D Synthon D is commercially available, for example, from Aldrich Chemical Company, Milwaukee, WI 53201 USA. Example E Preparation of Synthon E Synthon E is prepared from [l-bromobutyl]-N-(2,2,2-trifluoroethyl)-9H- fluorene-9-carboxamide (Example 11 in U.S. Patent No. 5,712,279) and methylamine . [ 1 -bromobutyl]-N-(2 ,2 ,2-trifluoroethyl)-9H-fluorene-9- carboxamide (29.5 g, 69.2 mmol), methylamine hydrochloride (5.06 g, 75.0 mmol), and anhydrous potassium carbonate (23.0 g, 166 mmol) are placed in a glass pressure vessel. Dimethylformamide (100 mL) is added, and the vessel is then sealed and heated at 50 °C for 48 h, cooled and concentrated to dryness, and taken up in 500 mL methylene chloride. The solution is washed with three 80 mL portions of saturated sodium bicarbonate solution and then two 80 mL portions of brine, followed by drying over magnesium sulfate and evaporation of solvent. The crude is fractionated by flash chromatography on 600 g silica gel, loading the mixmre in methylene chloride and then eluting with a step gradient of 2% to 3% methanol in methylene chloride (4 L total solvent volume). Fractions containing pure compound are combined and evaporated to yield Synthon E (22.5 g, 59.5 mmol, 86%) as a white foamy gum. Example F Preparation of Synthon F The preparation of Synthon F as the dihydrochloride salt is described as part of Example 10 in U.S. Patent No. 5,712,279. Example G Preparation of Synthon G Synthon G is commercially available, for example, from Aldrich Chemical Company, Milwaukee, WI 53201 USA. Example H Preparation of Synthon H The preparation of Synthon H as the dihydrochloride salt is described as part of Example 11 in U.S. Patent No. 5,712,279. Example I Preparation of Synthon I Synthon I is prepared by alkylation of Synthon F with 6-bromohexanoic acid. A solution of Synthon F hydrochloride (18.0 g, 49 mmol) in 100 mL dimethylformamide is stirred under argon at room temperamre and treated with potassium carbonate (12.6 g, 49 mmol) followed by 6-bromohexanoic acid (9.6 g, 49 mmol). The reaction is heated to 50°C for 24 h. After cooling, the reaction is filtered to remove potassium carbonate, and the filter cake is rinsed with ethyl acetate. The solvents are removed in vacuo to afford a solid from which Synthon I can be obtained as an off-white solid after recrystallization from ethyl acetate (18.6 g, 38.7 mmol, 79%). Example 1 Synthesis of A solution of 100 mmols of Synthon A in 200 mL of THF under Nj is treated at room temperamre with 100 mmols of trifluoroacetic anhydride and stirred for lhr. To the resultant mixmre is added a solution of 50 mmols of 1,3- diaminopropane and 200 mmols of triethylamine in 200 mL of THF. The temperamre is raised to 60 °C and the reaction followed by TLC. When the reaction is essentially complete by TLC, the solvent is removed in vacuo and the residue partitioned between ethyl acetate and water. The organic layer is washed with water, dried over sodium sulfate, filtered and the solvent removed. The final product is purified by crystallization or chromatography. Using this procedure, other compounds of formula I may be prepared by employing alternative diamine linker molecules and analogs of Synthon A. Example 2 Synthesis of A mixmre of 100 mmols of phthalic anhydride and 120 mmols of 1- amino-4-butanol in 200 mL of toluene is refluxed with azeotropic removal of water. The reaction is followed by TLC and when judged complete, is cooled and washed with IM HCI and water and dried over sodium sulfate. To this solution is added 100 mmols of triethylamine followed by 100 mmols of methanesulfonyl chloride with cooling. After lhr., the mixmre is washed with water, dried over sodium sulfate and the solvent removed in vacuo. The resulting phthalimide mesylate is dissolved in 100 mL of DMF and 100 mmols of Synthon E, 100 mmols of potassium carbonate and 50 mmols of potassium iodide are added.

Bioassay Example 1 Inhibition of Triglyceride Transfer MTP activity is routinely determined by measuring the rate of transfer of radiolabeled triglyceride from donor small unilamellar vesicles (SUV) to acceptor SUV. In this bioassay, the inhibition of radiolabled triglyceride transfer between donor and acceptor vesicles is determined using the procedure described in J. R. Wetterau et al., Biochim. Biophys. Acta 1997, 1345, 136- 150. A typical transfer reaction mixmre contains donor vesicles (40 nmol egg phosphatidyl choline, 0.25 mol% radiolabeled triglyceride ([ 14 C]triolein), and 7.5 mol% cardiolipin), acceptor vesicles (240 nmol egg phosphatidyl choline and 0.25% unlabeled triglyceride) and 5 mg bovine serum albumin in a total of 0.9 mL buffer. The negative charge in the donor vesicles due to the presence of cardiolipin facilitates the separation of donor and acceptor membranes. Following a transfer reaction, a DEAE-cellulose suspension is added to selectively bind the negatively charged donor vesicles. The DEAE- cellulose and bound donor membranes are then pelleted by low speed centrifugation. The acceptor SUV concentration in the assay mixmre is kept in excess over that of the donor SUV to minimize back transfer from acceptor to donor vesicles. First-order kinetics are used to quantify total lipid transfer. This corrects for the dilution of labeled lipid in the donor vesicles as the transfer reaction proceeds. The transfer activity is generally expressed as a percent of the donor lipid transferred per unit of time. Bioassay Example 2 Inhibition of Lipoprotein Secretion by HepG2 Cells In this bioassy, the inhibition of lipoprotein secretion by cultured human hepatoma cells (HepG2) is determined using the procedure described in H. Jamil et al., Proc. Natl. Acad. Sci. U.S.A. 1996, 93, 11991-11995. HepG2 cells are seeded at a density of approximately 50% confluency in 48-well plates and allowed to grow for 48 h before treatment. At this time, the medium is replaced with fresh medium containing 0.5% DMSO and a range of concentrations of the inhibitor. After a 16 h incubation under standard cell culture conditions, the medium is diluted with fresh tissue culture medium 30-fold for an apoB ELISA, and 60-fold for an apoAI ELISA. A sandwich ELISA is used to measure apoB in the media. A similar assay is used to quantitate apoAI. For the apoAI assay, the primary and secondary antibodies are a monoclonal anti-human apoAI (1:500 dilution) and a goat anti- human apoAI polyclonal antibody (1:500). The concentration of the respective proteins is measured against a 2-fold dilution standard curve from 1.25-40 ng/mL of the purified proteins. In this range of concentrations, both assays show a linear response. Each inhibitor concentration is tested in duplicate cultures, and apoB and apoAI are measured by ELISA in each culture in triplicate. Bioassay Example 3 Inhibition of Triglyceride Secretion in Rats In this bioassay, the inhibition of triglyceride secretion in fasted and fed rats is determined using the procedure described in J. R. Wetterau et al., Nature 1998, 282, 751-754. Sprague-Dawley rats ( ~ 200 g each, four per treatment group) are adapted to a reversed diurnal light cycle for two weeks. Before the experiment, the rats either are fasted or have free access to food for 18 hours. The animals are dosed with a test compound one hour before receiving an intravenous injection of Triton WR1339 (250 mg/kg), which prevents the catabolism of triglyceride-rich lipoproteins produced during the course of the experiment. The triglyceride secretion rate is determined by calculating the amount of triglyceride that is accumulated in plasma during the 2.5 hours after the Triton injection. The standard assay is linear for at least 5 hours after the Triton injection. Plasma triglyceride levels are determined with a Roche Cobas blood chemistry autoanalyzer. Bioassay Example 4 Diminution of Serium Cholesterol Levels in Hamsters In this bioassay, the diminution of serum cholesterol levels in hamsters is determined using the procedure described in J. R.

They are dosed once a day with a test compound and are allowed, free access to a standard hamster diet. After seven days of treatment, hamsters are fasted for 18 hours, after which plasma lipid levels (triglycerides and cholesterol) and chemistries are determined with a Roche Cobas blood chemistry autoanalyzer. Hamster lipoprotein fractions (VLDL, LDL, HDL) are quantitated after the precipitation of apoB-containing lipoproteins with phosphotungstate and magnesium chloride. Bioassay Example 5 Amelioration of Hyperlipidemia in WHHL Rabbits In this bioassay, the amelioration of hyperlipidemia in Watanabe- heritable hyperlipidemic (WHHL) rabbits is determined using the procedure described in J.
