Description: TITLE OF THE INVENTION A METHOD OF TREATING CANCER BACKGROUND OF THE INVENTION The present invention relates to methods of treating cancer using a combination of an antineoplastic agent and a compound which is an inhibitor of a prenyl-protein transferase. Chemotherapy, the systematic administration of antineoplastic agents that travel throughout the body via the blood circulatory system, along with and often in conjunction with surgery and radiation treatment, has for years been widely utilized in the treatment of a wide variety of cancers. Unfortunately, the available chemotherapeutic drugs often fail patients because they kill many healthy cells and thus bring on serious side effects that limit the doses physicians can administer. Prenylation of proteins by intermediates of the isoprenoid biosynthetic pathway represents a class of post-translational modification (Glomset, J. A., Gelb, M. H., and Farnsworth, C. C. (1990). Trends Biochem. Sci. 15, 139-142; Maltese, W. A. (1990). FASEB J. 4, 3319-3328). This modification typically is required for the membrane localization and function of these proteins. Prenylated proteins share characteristic C-terminal sequences including CaaX (C, Cys; a, usually aliphatic amino acid; X, another amino acid), XXCC, or XCXC. Three post-translational processing steps have been described for proteins having a C-terminal CaaX sequence: addition of either a 15 carbon (farnesyl) or 20 carbon (geranylgeranyl) isoprenoid to the Cys residue, proteolytic cleavage of the last 3 amino acids, and methylation of the new C-terminal carboxylate (Cox, A. D. and Der, C. J. (1992a). Critical Rev. Oncogenesis 3:365-400; Newman, C. M. H. and Magee, A. I. (1993). Biochim. Biophys. Ada 1155:79-96). Some proteins may also have a fourth modification: palmitoylation of one or two Cys residues N-terminal to the farnesylated Cys. While some mammalian cell proteins terminating in XCXC are carboxymethylated, it is not clear whether carboxy methylation follows prenylation of proteins terminat- ing with a XXCC motif (Clarke, S. (1992). Annu. Rev. Biochem. 61, 355-386). For all of the prenylated proteins, addition of the isoprenoid is the first step and is required for the subsequent steps (Cox, A. D. and Der, C. J. (1992a). Critical Rev. Oncogenesis 3:365-400; Cox, A. D. and Der, C. J. (1992b) Current Opinion Cell Biol. 4:1008-1016). Three enzymes have been described that catalyze protein prenylation: farnesyl-protein transferase (FPTase), geranylgeranyl- protein transferase type I (GGPTase-I), and geranylgeranyl-protein transferase type-II (GGPTase-II, also called Rab GGPTase). These enzymes are found in both yeast and mammalian cells (Clarke, 1992; Schafer, W. R. and Rine, J. (1992) Annu. Rev. Genet. 30:209-237). Each of these enzymes selectively uses farnesyl diphosphate (FPP) or geranyl-geranyl diphosphate as the isoprenoid donor and selectively recognizes the protein substrate. FPTase farnesylates CaaX-containing proteins that end with Ser, Met, Cys, Gin or Ala. For FPTase, CaaX tetrapeptides comprise the minimum region required for interaction of the protein substrate with the enzyme. The enzymological characterization of these three enzymes has demonstrated that it is possible to selectively inhibit one with little inhibitory effect on the others (Moores, S. L., Schaber, M. D., Mosser, S. D., Rands, E., OΗara, M. B., Garsky, V. M., Marshall, M. S., Pompliano, D. L., and Gibbs, J. B., /. Biol Chem., 266:17438 (1991), U.S. Pat. No. 5,470,832). The prenylation reactions have been shown genetically to be essential for the function of a variety of proteins (Clarke, 1992; Cox and Der, 1992a; Gibbs, J. B. (1991). Cell 65: 1-4; Newman and Magee, 1993; Schafer and Rine, 1992). This requirement often is demonstrated by mutating the CaaX Cys acceptors so that the proteins can no longer be prenylated. The resulting proteins are devoid of their central biological activity. These studies provide a genetic "proof of principle" indicating that inhibitors of prenylation can alter the physiological responses regulated by prenylated proteins. The Ras protein is part of a signalling pathway that links cell surface growth factor receptors to nuclear signals initiating cellular proliferation. Biological and biochemical studies of Ras action indicate that Ras functions like a G-regulatory protein. In the inactive state, Ras is bound to GDP. Upon growth factor receptor activation, Ras is induced to exchange GDP for GTP and undergoes a conformational change. The GTP-bound form of Ras propagates the growth stimulatory signal until the signal is terminated by the intrinsic GTPase activity of Ras, which returns the protein to its inactive GDP bound form (D.R. Lowy and D.M. Willumsen, Ann. Rev. Biochem. 62:851-891 (1993)). Activation of Ras leads to activation of multiple intracellular signal transduction pathways, including the MAP Kinase pathway and the Rho Rac pathway (Joneson et al, Science 277:810-812). Mutated ras genes are found in many human cancers, including colorectal carcinoma, exocrine pancreatic carcinoma, and myeloid leukemias. The protein products of these genes are defective in their GTPase activity and constitutively transmit a growth stimulatory signal. The Ras protein is one of several proteins that are known to undergo post-translational prenylation. Farnesyl-protein transferase utilizes farnesyl pyrophosphate to covalently modify the Cys thiol group of the Ras CAAX box with a farnesyl group (Reiss et al, Cell, 62:81-88 (1990); Schaber et al, J. Biol Chem., 265:14701-14704 (1990); Schafer et al, Science, 249:1133-1139 (1990); Manne et al, Proc. Natl Acad. Sci USA, §7:7541-7545 (1990)). Ras must be localized to the plasma membrane for both normal and oncogenic functions. At least 3 post-translational modifications are involved with Ras membrane localization, and all 3 modifications occur at the C- terminus of Ras. The Ras C-terminus contains a sequence motif termed a "CAAX" or box (Cys is cysteine, Aaa is an aliphatic amino acid, the Xaa is any amino acid) (Willumsen et al, Nature 370:583-586 (1984)). Depending on the specific sequence, this motif serves as a signal sequence for the enzymes farnesyl-protein transferase or geranylgeranyl-protein transferase, which catalyze the alkylation of the cysteine residue of the CAAX motif with a C15 or C20 isoprenoid, respectively. (S. Clarke., Ann. Rev. Biochem. 67:355-386 (1992); W.R. Schafer and J. Rine, Ann. Rev. Genetics 30:209-237 (1992)). Other farnesylated proteins include the Ras-related GTP- binding proteins such as RhoB, fungal mating factors, the nuclear lamins, and the gamma subunit of transducin. James, et al., J. Biol Chem. 269, 14182 (1994) have identified a peroxisome associated protein Pxf which is also farnesylated. James, et al., have also suggested that there are farnesylated proteins of unknown structure and function in addition to those listed above. Inhibitors of farnesyl-protein transferase have been described in two general classes. The first class includes analogs of FPP, while the second is related to protein substrates (e.g., Ras) for the enzyme. The peptide derived inhibitors that have been described are generally cysteine containing molecules that are related to the CAAX motif that is the signal for protein prenylation. (Schaber et al, ibid; Reiss et. al, ibid; Reiss et al, PNAS, 88:132-136 (1991)). Such inhibitors may inhibit protein prenylation while serving as alternate substrates for the farnesyl-protein transferase enzyme, or may be purely competitive inhibitors (U.S. Patent 5,141,851, University of Texas; N.E. Kohl et al, Science, 260:1934-1937 (1993); Graham, et al., /. Med. Chem., 37, 725 (1994)). Mammalian cells express four types of Ras proteins (H-, N-, K4A-, and K4B-Ras) among which K-Ras4B is the most frequently mutated form of Ras in human cancers. Inhibition of farnesyl-protein transferase has been shown to block the growth of H-ras-transformed cells in soft agar and to modify other aspects of their transformed phenotype. It has also been demonstrated that certain inhibitors of farnesyl-protein transferase selectively block the processing of the H-Ras oncoprotein intracellularly (N.E. Kohl et al, Science, 260:1934- 1937 (1993) and G.L. James et al, Science, 260:1937-1942 (1993). Recently, it has been shown that an inhibitor of farnesyl-protein transferase blocks the growth of H-ra-s-dependent tumors in nude mice (N.E. Kohl et al, Proc. Natl Acad. Sci U.S.A., 97:9141-9145 (1994) and induces regression of mammary and salivary carcinomas in H-ras transgenic mice (N.E. Kohl et al, Nature Medicine, 1:792-797 (1995). Indirect inhibition of farnesyl-protein transferase in vivo has been demonstrated with lovastatin (Merck & Co., Rahway, NJ) and compactin (Hancock et al, ibid; Casey et al, ibid; Schafer et al, Science 245:319 (1989)). These drugs inhibit HMG-CoA reductase, the rate limiting enzyme for the production of polyisoprenoids including farnesyl pyrophosphate. Inhibition of farnesyl pyrophosphate biosynthesis by inhibiting HMG-CoA reductase blocks Ras membrane localization in cultured cells. Because prenyl pyrophosphates are intermediates in many biosynthetic processes, direct inhibition of a prenyl-protein transferase would be more specific and attended by fewer side effects than would occur with the required dose of a general inhibitor of isoprene biosynthesis. It is the object of the instant invention to provide a composition that comprises an antineoplastic agent and a prenyl-protein transferase inhibitor whose therapeutic effect in combination may allow use of the antineoplastic agent at a dose which is lower than the dose of the antineoplastic agent if it was used alone and may therefore ameliorate some of the unwanted side effects normally associated with traditional chemotherapy. A pharmaceutically effective combination of an antineoplastic agent and a prenyl-protein transferase inhibitor are used in the present invention to treat cancer, such as in tumor cells that are less susceptable to treatment by antagonist of the antineoplastic agent or prenyl-protein transferase inhibitor when administered alone. SUMMARY OF THE INVENTION A method of treating cancer is disclosed which is comprised of administering to a mammalian patient in need of such treatment an effective amount of a combination of an antineoplastic agent and a prenyl-protein transferase inhibitor. Preferably an antineoplastic agent and a farnesyl protein transferase inhibitor are used in such a combination.

J. Cancer, 27:274-281 (1978)), which were treated for four (4) hours with paclitaxel and then washed, were treated in anchorage-dependent and -independent growth assays in the absence or presence of 0.2 μM, 2 μM or 20 μM Compound A.

FIGURES 4 and 4A-4L: Effect of a Farnesyl-protein Transferase Inhibitor in combination with paclitaxel on the cell cycle of MCF-7 Cells: MCF-7 cells were preincubated for one day, followed by a 24 hour treatment with various concentrations of paclitaxel in the presence or absence of 1 μM Compound A. The DNA contents of the cells were then assessed according to the protocol described in "In vitro cell cycle assay." The cell population having various DNA quantities was then determined and analyzed graphically. Figure 4 shows a composite of 12 cell DNA-content histograms representing the various treatment combinations. Figures 4A-4L show the individual histograms in greater detail. Figures 4A-4F show the histograms of the treatment in the absence of Compound A and with increasing concentrations of paclitaxel (the left column of Figure 4). Figures 4G-4L show the histograms of the treatment in the presence of 1 μM of Compound A and with increasing concentrations of paclitaxel (the right column of Figure 4). The addition of Compound A increases the molar potency with which paclitaxel causes G2 M phase arrest in MCF-7 cells. FIGURE 5: Specific Effect of a Farnesyl-protein Transferase Inhibitor in combination with paclitaxel on the cell cycle of MCF-7 Cells: The cells which contained the doubled DNA content from the assay described above for Figures 4 and 4A-4L were analyzed to determine which particular cell cycle phase was affected by the addition of Compound A to the paclitaxel treatment. Thus, aliquots of the cell populations for the various paclitaxel/Compound A treatments were fixed in 3% paraformaldehyde for 10 minutes, washed in PBS and stained in 24 μg/ml bis-benzimide in PBS. Mitotic cells were distinquished from interphase cells under fluorescence microscopy by characteristic chromatin condensation and mitotic indices were obtained by manual counting of 1000 cells in each experimental treatment group. The results of those counts are shown in Figure 5. The results show that the enhancement in blockage at the G2 M phase of the cell cycle is largely due to an effect on the M-phase.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of treating cancer which is comprised of admininstering to a mammalian patient in need of such treatment an effective amount of a combination of an antineoplastic agent and a prenyl-protein transferase inhibitor. The present method of treating cancer by simultaneously inhibiting protein prenylation and interfering with DNA replication and/or inducing apoptosis offers advantages over previously disclosed methods which utilize a prenyl- protein transferase inhibitor or an antineoplastic agent alone, in that the inhibitory activity and dosage of the instant combination of inhibitors of prenyl-protein transferase and anti-neoplastic agents can be individually varied depending on the nature of the cancer cells to be treated. Any compounds which act as an antineoplastic agent and any compounds which inhibit prenyl-protein transferase can be used in the instant method. Preferably the compounds utilized in the instant combination are an antineoplastic agent and a farnesyl-protein transferase inhibitor. When practicing the present method the antineoplastic agent and the inhibitor of prenyl-protein transferase may be administered either sequentially in any order or simultaneously. It is anticipated that the therapeutic effect of the instant compositions may be achieved with smaller amounts of the antineoplastic agents and prenyl-protein transferase inhibitors than would be required if such antineoplastic agents and a prenyl-protein transferase inhibitors were administered alone, thereby avoiding any non-mechanism-based adverse toxicity effects which might result from administration of an amount of the single antineoplastic agent or prenyl- protein transferase inhibitor sufficient to achieve the same therapeutic effect. It is also anticipated that the instant compositions will achieve a synergistic therapeutic effect or will exhibit unexpected therapeutic advantage over the effect of any of the component compounds if administered alone. As used herein the term an antineoplastic agent refers to compounds which either prevent cancer cells from multiplying by interfering with the cell's ability to replicate DNA or induce apoptosis in the cancerous cells. The term prenyl-protein transferase inhibiting compound refers to compounds which antagonize, inhibit or counteract the expression of the gene coding a prenyl-protein transferase or the activity of the protein product thereof. The term farnesyl protein transferase inhibiting compound likewise refers to compounds which antagonize, inhibit or counteract the expression of the gene coding farnesyl-protein transferase or the activity of the protein product thereof. The term selective as used herein refers to the inhibitory activity of the particular compound against a prenyl-protein transferase activity or farnesyl-protein transferase activity. Preferably, for example, a selective inhibitor of farnesyl-protein transferase exhibits at least 20 times greater activity against farnesyl-protein transferase when comparing its activity against another receptor or enzymatic activity, respectively. More preferably the selectivity is at least 100 times or more. The extent of selectivity of the two inhibitors that comprise the method of the instant invention may effect the advantages that the method of treatment claimed herein offers over previously disclosed methods of using a single antineoplastic agent or prenyl- protein transferase inhibitor for the treatment of cancer. In particular, use of two independent pharmaceutically active components that have complementary, essentially non-overlapping activities allows the person utilizing the instant method of treatment to independently and accurately vary the inhibitory activity of the combination without having to synthesize a single drug having a particular pharmaceutical activity profile. The term "synergistic" as used herein means that the effect achieved with the methods and compositions of this invention is greater than the sum of the effects that result from methods and compositions comprising the prenyl-protein transferase inhibitor and antineoplastic agent of this invention separately and in the amounts employed in the methods and compositions hereof. Such synergy between the two active ingredients enabling smaller doses to be given and preventing or delaying the build up of multi-drug resistance. The preferred therapeutic effect provided by the instant composition is the treatment of cancer and specifically the inhibition of cancerous tumor growth and/or the regression of cancerous tumors. Cancers which are treatable in accordance with the invention described herein include cancers of the brain, breast, colon, genitourinary tract, lymphatic system, pancreas, rectum, stomach, larynx, liver, lung and prostate. More particularly, such cancers include histiocytic lymphoma, lung adenocarcinoma, pancreatic carcinoma, colo-rectal carcinoma, small cell lung cancers and neurological tumors. The composition of this invention is also useful for inhibiting other proliferative diseases, both benign and malignant, wherein Ras proteins are aberrantly activated as a result of oncogenic mutation in other genes (i.e., the Ras gene itself is not activated by mutation to an oncogenic form) with said inhibition being accomplished by the administration of an effective amount of the instant composition to a mammal in need of such treatment. For example, a component of NF-1 is a benign proliferative disorder. The composition of the instant invention is also useful in the prevention of restenosis after percutaneous transluminal coronary angioplasty by inhibiting neointimal formation (C. Indolfi et al. Nature medicine, 1:541-545(1995). The instant composition may also be useful in the treatment and prevention of polycystic kidney disease (D.L. Schaffner et al. American Journal of Pathology, 142: 1051-1060 (1993) and B. Cowley, Jr. et al.FASEB Journal, 2: A3160 (1988)). The pharmaceutical composition of this invention may be administered to mammals, preferably humans, either alone or, prefer- ably, in combination with pharmaceutically acceptable carriers or diluents, optionally with known adjuvants, such as alum, in a pharmaceutical composition, according to standard pharmaceutical practice. The compounds can be administered orally or parenterally, including the intravenous, intramuscular, intraperitoneal, subcutaneous, rectal and topical routes of administration. For oral use of a chemotherapeutic combination according to this invention, the selected combination or compounds may be administered, for example, in the form of tablets or capsules, or as an aqueous solution or suspension. In the case of tablets for oral use, carriers which are commonly used include lactose and corn starch, and lubricating agents, such as magnesium stearate, are commonly added. For oral administration in capsule form, useful diluents include lactose and dried corn starch. When aqueous suspensions are required for oral use, the active ingredients are combined with emulsifying and suspend- ing agents. If desired, certain sweetening and/or flavoring agents may be added. For intramuscular, intraperitoneal, subcutaneous and intravenous use, sterile solutions of the active ingredient are usually prepared, and the pH of the solutions should be suitably adjusted and buffered. For intravenous use, the total concentration of solutes should be controlled in order to render the preparation isotonic. The combinations of the instant invention may also be co-administered with other well known therapeutic agents that are selected for their particular usefulness against the condition that is being treated. If formulated as a fixed dose, such combination products employ the combinations of this invention within the dosage range described below and the other pharmaceutically active agent(s) within its approved dosage range. Combinations of the instant invention may alternatively be used sequentially with known pharmaceutically acceptable agent(s) when a multiple combination formulation is inappropriate. The instant invention encompasses a method of treatment wherein an antineoplastic agent and an inhibitor of prenyl-protein transferase are administered simultaneously or sequentially. Thus, while a pharmaceutical formulation comprising an antineoplastic agent and an inhibitor of prenyl-protein transferase may be advantageous for administering the combination for one particular treatment, sequential administration of the components of the combination may be advantageous in another treatment. It is also understood that the instant combination of antineoplastic agent and inhibitor of prenyl- protein transferase may be used in conjunction with other methods of treating cancer and/or tumors, including radiation therapy and surgery. Radiation therapy, including x-rays or gamma rays which are delivered from either an externally applied beam or by implantation of tiny radioactive sources, may also be used in combination with an inhibitor of prenyl-protein transferase alone to treat cancer. The prenyl-protein transferase inhibitors may either be administered concurrently with the radiation therapy or may be administered prior to the application of the radiation. In a particularly useful example of the method comprises of combining radiation therapy and administering an inhibitor of prenyl- protein transferase, a farnesyl-protein transferase inhibitor which is: 2(S)-[2(S)-[2(R)-Amino-3-mercapto]-proρylamino- 3(S)-methyl]-pentyloxy-3-phenylpropionyl-methionine sulfone isopropyl ester (Compound A); is administered prior to the application of radiation therapy. In another particularly useful example of the method comprises of combining radiation therapy and administering an inhibitor of prenyl-protein transferase, a farnesyl-protein transferase inhibitor which is: l-(3-Chlorophenyl)-4-[l-(4-cyanobenzyl)-5-imidazolylmethyl]-2- piperazinone; or a pharmaceutically acceptable salt thereof; is administered prior to the application of radiation therapy. In another particularly useful example of the method comprises of combining radiation therapy and administering an inhibitor of prenyl-protein transferase, a farnesyl-protein transferase inhibitor which is: (R)-l-(3-Chlorophenyl)-4-[l-(4-cyanobenzyl)-5-imidazolylmethyl]- 5- [2- (ethanesulf ony l)methy 1] -2-piperazinone ; or a pharmaceutically acceptable salt thereof; is administered prior to the application of radiation therapy. In another particularly useful example of the method comprises of combining radiation therapy and administering an inhibitor of prenyl-protein transferase, a farnesyl-protein transferase inhibitor which is: 4-[l-(5-Chloro-2-oxo-2H-[l,2']bipyridinyl-5 , -ylmethyl)-lH-pyrrol-2- ylmethyl] -benzonitrile ; or a pharmaceutically acceptable salt thereof; is administered prior to the application of radiation therapy. In another particularly useful example of the method comprises of combining radiation therapy and administering an inhibitor of prenyl-protein transferase, a farnesyl-protein transferase inhibitor which is: l-[N-(l-(4-cyanobenzyl)-5-imidazolylmethyl)-N-(4- cyanobenzyl)amino]-4-(phenoxy)benzene; or a pharmaceutically acceptable salt thereof; is administered prior to the application of radiation therapy. The present invention also encompasses a pharmaceutical composition useful in the treatment of cancer, comprising the administration of a therapeutically effective amount of the combinations of this invention, with or without pharmaceutically acceptable carriers or diluents. Suitable compositions of this invention include aqueous solutions comprising compounds of this invention and pharmacologically acceptable carriers, e.g., saline, at a pH level, e.g., 7.4. The solutions may be introduced into a patient's blood-stream by local bolus injection. When a combination according to this invention is administered into a human subject, the daily dosage will normally be determined by the prescribing physician with the dosage generally varying according to the age, weight, and response of the individual patient, as well as the severity of the patient's symptoms. In one exemplary application, a suitable amount of an antineoplastic agent and a prenyl-protein transferase inhibitor are administered to a mammal undergoing treatment for cancer. Administration occurs in an amount of each type of inhibitor of between about 0.1 mg/kg of body weight to about 60 mg/kg of body weight per day, preferably of between 0.5 mg/kg of body weight to about 40 mg/kg of body weight per day. A particular therapeutic dosage that comprises the instant composition includes from about O.Olmg to about 500mg of an antineoplastic agent and from about O.Olmg to about 500mg of a prenyl-protein transferase inhibitor. Preferably, the dosage comprises from about lmg to about lOOmg of an antineoplastic agent and from about lmg to about lOOmg of a prenyl- protein transferase inhibitor. Examples of an antineoplastic agent include, in general, microtubule-stabilising agents ( such as paclitaxel (also known as Taxol®), docetaxel (also known as Taxotere®), epothilone A, epothilone B, desoxy epothilone A, desoxy epothilone B or their derivatives); microtubule-disruptor agents; alkylating agents, anti- metabolites; a fusel poison; epidophyllotoxin; an antineoplastic enzyme; a topoisomerase inhibitor; procarbazine; mitoxantrone; platinum coordination complexes; biological response modifiers and growth inhibitors; hormonal/anti-hormonal therapeutic agents and haematopoietic growth factors. Example classes of antineoplastic agents include, for example, the anthracycline family of drugs, the vinca drugs, the mitomycins, the bleomycins, the cytotoxic nucleosides, the taxanes, the epothilones, discodermolide, the pteridine family of drugs, diynenes and the podophyllotoxins. Particularly useful members of those classes include, for example, doxorubicin, carminomycin, daunorubicin, aminopterin, methotrexate, methopterin, dichloro-methotrexate, mitomycin C, porfiromycin, 5-fluorouracil, 6-mercaptopurine, gemcitabine, cytosine arabinoside, podophyllotoxin or podo-phyllotoxin derivatives such as etoposide, etoposide phosphate or teniposide, melphalan, vinblastine, vincristine, leurosidine, vindesine, leurosine, paclitaxel and the like. Other useful antineoplastic agents include estramustine, cisplatin, carboplatin, cyclophosphamide, bleomycin, tamoxifen, ifosamide, melphalan, hexamethyl melamine, thiotepa, cytarabin, idatrexate, trimetrexate, dacarbazine, L-asparaginase, camptothecin, CPT-11, topotecan, ara-C, bicalutamide, flutamide, leuprolide, pyridobenzoindole derivatives, interferons and interleukins. The preferred class of antineoplastic agents is the taxanes and the preferred antineoplastic agent is paclitaxel.

It is intended that the definition of any substituent or variable (e.g., RlO, Z, n, etc.) at a particular location in a molecule be independent of its definitions elsewhere in that molecule. Thus, -N(RlO)2 represents -NHH, -NHCH3, -NHC2H5, etc. It is understood that substituents and substitution patterns on the compounds of the instant invention can be selected by one of ordinary skill in the art to provide compounds that are chemically stable and that can be readily synthesized by techniques known in the art as well as those methods set forth below. The pharmaceutically acceptable salts of the compounds of this invention can be synthesized from the compounds of this invention which contain a basic moiety by conventional chemical methods. Generally, the salts are prepared by reacting the free base with stoichiometric amounts or with an excess of the desired salt-forming inorganic or organic acid in a suitable solvent or various combinations of solvents. The compounds of formula (Il-h) can be synthesized from their constituent amino acids by conventional peptide synthesis techniques, and the additional methods described below. Standard methods of peptide synthesis are disclosed, for example, in the following works: Schroeder et al, "The Peptides", Vol. I, Academic Press 1965, or Bodanszky et al, "Peptide Synthesis", Interscience Publishers, 1966, or McOmie (ed.)

The compounds are useful in various pharmaceutically acceptable salt forms. The term "pharmaceutically acceptable salt" refers to those salt forms which would be apparent to the pharma- ceutical chemist, i.e., those which are substantially non-toxic and which provide the desired pharmacokinetic properties, palatability, absorption, distribution, metabolism or excretion. Other factors, more practical in nature, which are also important in the selection, are cost of the raw materials, ease of crystallization, yield, stability, hygroscopicity and flowability of the resulting bulk drug. Conveniently, pharmaceutical compositions may be prepared from the active ingredients in combination with pharmaceutically acceptable carriers. Pharmaceutically acceptable salts include conventional non-toxic salts or quarternary ammonium salts formed, e.g., from non-toxic inorganic or organic acids. Non- toxic salts include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, nitric and the like; and the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, sulfanilic, 2-acetoxybenzoic, fumaric, toluenesulfonic, methane- sulfonic, ethane disulfonic, oxalic, isethionic, trifluoroacetic and the like. The pharmaceutically acceptable salts of the present invention can be synthesized by conventional chemical methods. Generally, the salts are prepared by reacting the free base or acid with stoichiometric amounts or with an excess of the desired salt- forming inorganic or organic acid or base, in a suitable solvent or solvent combination. The farnesyl transferase inhibitors of formula (II- a) through (II-c) can be synthesized in accordance with Schemes 1-22, in addition to other standard manipulations such as ester hydrolysis, cleavage of protecting groups, etc., as may be known in the literature or exemplified in the experimental procedures. Substituents R, R a and R D , as shown in the Schemes, represent the substituents R^, R3, R4, a nd R5; however their point of attachment to the ring is illustrative only and is not meant to be limiting. These reactions may be employed in a linear sequence to provide the compounds of the invention or they may be used to synthesize fragments which are subsequently joined by the alkylation reactions described in the Schemes. Synopsis of Schemes 1-22: The requisite intermediates are in some cases commercially available, or can be prepared according to literature procedures, for the most part. In Scheme 1, for example, the synthesis of 2-alkyl substituted piperazines is outlined, and is essentially that described by J. S. Kiely and S. R. Priebe in Organic Preparations and Proceedings Int.. 1990, 22, 761-768. Boc-protected amino acids I, available commer- cially or by procedures known to those skilled in the art, can be coupled to N-benzyl amino acid esters using a variety of dehydrating agents such as DCC (dicyclohexycarbodiimide) or EDC HC1 (l-ethyl-3-(3-dimethyl- aminopropyl)carbodiimide hydrochloride) in a solvent such as methylene chloride , chloroform, dichloroethane, or in dimethylformamide. The product II is then deprotected with acid, for example hydrogen chloride in chloroform or ethyl acetate, or trifluoroacetic acid in methylene chloride, and cyclized under weakly basic conditions to give the diketopiperazine III. Reduction of III with lithium aluminum hydride in refluxing ether gives the piperazine IN, which is protected as the Boc derivative N. The Ν-benzyl group can be cleaved under standard conditions of hydrogenation, e.g., 10% palladium on carbon at 60 psi hydrogen on a Parr apparatus for 24-48 h. The product VI can be treated with an acid chloride, or a carboxylic acid under standard dehydrating conditions to furnish the carboxamides VII; a final acid deprotection as previously described gives the intermediate VIII (Scheme 2). The intermediate VIII can be reductively alkylated with a variety of aldehydes, such as IX. The aldehydes can be prepared by standard procedures, such as that described by O. P. Goel, U. Krolls, M. Stier and S. Kesten in Organic Syntheses. 1988, 67, 69-75, from the appropriate amino acid (Scheme 3). The reductive alkylation can be accomplished at pH 5-7 with a variety of reducing agents, such as sodium triacetoxyborohydride or sodium cyanoborohydride in a solvent such as dichloroethane, methanol or dimethylformamide. The product X can be deprotected to give the final compounds XI with trifluoro- acetic acid in methylene chloride. The final product XI is isolated in the salt form, for example, as a trifluoroacetate, hydrochloride or acetate salt, among others. The product diamine XI can further be selectively protected to obtain XII, which can subsequently be reductively alkylated with a second aldehyde to obtain XIII. Removal of the protecting group, and conversion to cyclized products such as the dihydroimidazole XV can be accomplished by literature procedures. Alternatively, the protected piperazine intermediate VII can be reductively alkylated with other aldehydes such as l-trityl-4- imidazolyl-carboxaldehyde or l-trityl-4-imidazolylacetaldehyde, to give products such as XVI (Scheme 4). The trityl protecting group can be removed from XVI to give XVII, or alternatively, XVI can first be treated with an alkyl halide then subsequently deprotected to give the alkylated imidazole XVIII. Alternatively, the intermediate VIII can be acylated or sulfonylated by standard techniques. The imidazole acetic acid XIX can be converted to the acetate XXI by standard procedures, and XXI can be first reacted with an alkyl halide, then treated with refluxing methanol to provide the regiospecifically alkylated imidazole acetic acid ester XXII. Hydrolysis and reaction with piperazine VIII in the presence of condensing reagents such as l-(3-dimethylaminopropyl)- 3-ethylcarbodiimide (EDC) leads to acylated products such as XXIV. If the piperazine VIII is reductively alkylated with an aldehyde which also has a protected hydroxyl group, such as XXV in Scheme 6, the protecting groups can be subsequently removed to unmask the hydroxyl group (Schemes 6, 7). The alcohol can be oxidized under standard conditions to e.g. an aldehyde, which can then be reacted with a variety of organometallic reagents such as Grignard reagents, to obtain secondary alcohols such as XXIX. In addition, the fully deprotected amino alcohol XXX can be reductively alkylated (under conditions described previously) with a variety of aldehydes to obtain secondary amines, such as XXXI (Scheme 7), or tertiary amines. The Boc protected amino alcohol XXVII can also be utilized to synthesize 2-aziridinylmethylpiperazines such as XXXII (Scheme 8). Treating XXVII with l,r-sulfonyldiimidazole and sodium hydride in a solvent such as dimethylformamide led to the formation of aziridine XXXII. The aziridine reacted in the presence of a nucleophile, such as a thiol, in the presence of base to yield the ring-opened product XXXIII. In addition, the piperazine VIII can be reacted with aldehydes derived from amino acids such as O-alkylated tyrosines, according to standard procedures, to obtain compounds such as XXXIX. When R' is an aryl group, XXXIX can first be hydrogenated to unmask the phenol, and the amine group deprotected with acid to produce XL. Alternatively, the amine protecting group in XXXIX can be removed, and O-alkylated phenolic amines such as XLI produced. Depending on the identity of the amino acid I, various side chains can be incorporated into the piperazine. For example when I is the Boc-protected β-benzyl ester of aspartic acid, the intermediate diketopiperazine XLII where n=l and R=benzyl is obtained, as shown in Scheme 10. Subsequent lithium aluminum hydride reduction reduces the ester to the alcohol XLIII, which can then be reacted with a variety of alkylating agents such as an alkyl iodide, under basic conditions, for example, sodium hydride in dimethylformamide or tetrahydrofuran. The resulting ether XLIV can then be carried on to final products as described in Schemes 3-9. N-Aryl piperazines can be prepared as described in Scheme 11. An aryl amine XLV is reacted with bis -chloroethyl amine hydro- chloride (XLVI) in refluxing n -butanol to furnish compounds XLVII. The resulting piperazines XLVII can then be carried on to final products as described in Schemes 3-9. Piperazin-5-ones can be prepared as shown in Scheme 12. Reductive amination of Boc-protected amino aldehydes XLIX (prepared from I as described previously) gives rise to compound L. This is then reacted with bromoacetyl bromide under Schotten-Baumann conditions; ring closure is effected with a base such as sodium hydride in a polar aprotic solvent such as dimethylformamide to give LI. The carbamate protecting group is removed under acidic conditions such as trifluoroacetic acid in methylene chloride, or hydrogen chloride gas in methanol or ethyl acetate, and the resulting piperazine can then be carried on to final products as described in Schemes 3-9. The isomeric piperazin-3-ones can be prepared as described in Scheme 13. The imine formed from arylcarboxamides LII and 2- aminoglycinal diethyl acetal (LIII) can be reduced under a variety of conditions, including sodium triacetoxyborohydride in dichloroethane, to give the amine LIV. Amino acids I can be coupled to amines LIV under standard conditions, and the resulting amide LV when treated with aqueous acid in tetrahydrofuran can cyclize to the unsaturated LVI. Catalytic hydrogenation under standard conditions gives the requisite intermediate LVII, which is elaborated to final products as described in Schemes 3-9. Access to alternatively substituted piperazines is described in Scheme 14. Following deprotection with trifluoroacetic acid, the N-benzyl piperazine V can be acylated with an aryl carboxylic acid. The resulting N-benzyl aryl carboxamide LIX can be hydrogenated in the presence of a catalyst to give the piperazine carboxamide LX which can then be carried on to final products as described in Schemes 3-9. Reaction Scheme 15 provides an illustrative example the synthesis of compounds of the instant invention wherein the substituents R^ and R3 are combined to form - (CH2)u -• For example, 1-aminocyclohexane-l -carboxylic acid LXI can be converted to the spiropiperazine LXVI essentially according to the procedures outlined in Schemes 1 and 2. The piperazine intermediate LXIX can be deprotected as before, and carried on to final products as described in Schemes 3-9. It is understood that reagents utilized to provide the substituent Y which is 2-(naphthyl) and the imidazolylalkyl substituent may be readily replaced by other reagents well known in the art and readily available to provide other N-substituents on the piperazine. The aldehyde XLIX from Scheme 12 can also be reductively alkylated with an aniline as shown in Scheme 16. The product LXXI can be converted to a piperazinone by acylation with chloroacetyl chloride to give LXXII, followed by base-induced cyclization to LXXIII. Deprotection, followed by reductive alkylation with a protected imidazole carboxaldehyde leads to LXXV, which can be alkylation with an arylmethylhalide to give the imidazolium salt LXXVI. Final removal of protecting groups by either solvolysis with a lower alkyl alcohol, such as methanol, or treatment with triethylsilane in methylene chloride in the presence of trifluoroacetic acid gives the final product LXXVII. Scheme 17 illustrates the use of an optionally substituted homoserine lactone LXXIX to prepare a Boc-protected piperazinone LXXXII. Intermediate LXXXII may be deprotected and reductively alkylated or acylated as illustrated in the previous Schemes. Alternatively, the hydroxyl moiety of intermediate LXXXII may be mesylated and displaced by a suitable nucleophile, such as the sodium salt of ethane thiol, to provide an intermediate LXXXIII. Intermediate LXXXII may also be oxidized to provide the carboxylic acid on intermediate LXXXIV, which can be utilized form an ester or amide moiety. Amino acids of the general formula LXXXVI which have a sidechain not found in natural amino acids may be prepared by the reactions illustrated in Scheme 18 starting with the readily prepared imine LXXXV. Schemes 19-22 illustrate syntheses of suitably substituted aldehydes useful in the syntheses of the instant compounds wherein the variable W is present as a pyridyl moiety. Similar synthetic strategies for preparing alkanols that incorporate other heterocyclic moieties for variable W are also well known in the art.

Substituents R^, R6 and R^, as shown in the Schemes, represent the substituents R 2 , R , R4, R5, R6a, R6b, ROC, R6d and R8; although only one such R2, R or R^ is present in the intermediates and products of the schemes, it is understood that the reactions shown are also applicable when such aryl or heteroaryl moieties contain multiple substituents. The compounds referred to in the Synopsis of Schemes 23-36 by Roman numerals are numbered starting sequentially with I and ending with XXN. These reactions may be employed in a linear sequence to provide the compounds of the invention or they may be used to synthesize fragments which are subsequently joined by the alkylation reactions described in the Schemes. Aryl-aryl coupling is generally described in "Comprehensive Organic Functional Group Transformations," Katritsky et al. eds., pp 472-473, Pergamon Press (1995). Synopsis of Schemes 23-36: The requisite intermediates are in some cases commercially available, or can be prepared according to literature procedures, for the most part. Schemes 23-35 illustrate synthesis of the compounds of the formula Il-d which incoφorate a preferred benzylimidazolyl sidechain. In Scheme 23, for example, a biaryl intermediate that is not commercially available may be synthesized by methods known in the art. Thus, a suitably substituted phenyl boronic acid I may be reacted under Suzuki coupling conditions (Pure Appl. Chem., 63:419 (1991)) with a suitably substituted halogenated benzoic acid, such as 4-bromobenzoic acid, to provide the biaryl carboxylic acid II. The acid may be reduced and the triflate of the intermediate alcohol III may be formed in situ and coupled to a suitably substituted benzylimidazolyl IV to provide, after deprotection, the instant compound V. Schemes 24-27 illustrate other methods of synthesizing the key alcohol intermediates, which can then be processed as described in Scheme 23. Thus, Scheme 24 illustrates the analogous series of biaryl alcohol forming reactions starting with the halogenated biarylaldehyde. Scheme 25 illustrates the reaction wherein the "terminal" phenyl moiety is employed in the Suzuki coupling as the halogenated reactant. Such a coupling reaction is also compatible when one of the reactants incoφorates a suitably protected hydroxyl functionality as illustrated in Scheme 26. Negishi chemistry (Org. Synth., 66:67 (1988)) may also be employed to form the biaryl component of the instant compounds, as shown in Scheme 27. Thus, a suitably substituted zinc bromide adduct may be coupled to a suitably substituted aryl halide in the presence of nickel (II) to provide the biaryl VII. The aryl halide and the zinc bromide adduct may be selected based on the availability of the starting reagents. Scheme 28 illustrates the preparation of a suitably substituted biphenylmethyl bromide which could also be utilized in the reaction with the protected imidazole as described in Scheme 1. As illustrated in Scheme 29, the sequence of coupling reactions may be modified such that the biphenyl bond is formed last. Thus, a suitably substituted imidazole may first be alkylated with a suitably substituted benzyl halide to provide intermediate VIII. Intermediate VIII can then undergo Suzuki type coupling to a suitably substituted phenyl boronic acid. Scheme 30 illustrates synthesis of an instant compound wherein a non-hydrogen R9b is incorporated in the instant compound. Thus, a readily available 4-substituted imidazole IX may be selectively iodinated to provide the 5-iodoimidazole X. That imidazole may then be protected and coupled to a suitably substituted benzyl moiety to provide intermediate XI. Intermediate XI can then undergo the alkylation reactions that were described hereinabove. Scheme 31 illustrates synthesis of instant compounds that incoφorate a preferred imidazolyl moiety connected to the biaryl via an alkyl amino, sulfonamide or amide linker. Thus, the 4-aminoalkyl- imidazole XII, wherein the primary amine is protected as the phthalimide, is selectively alkylated then deprotected to provide the amine XIII. The amine XIII may then react under conditions well known in the art with various activated biaryl moieties to provide the instant compounds shown. Compounds of the instant invention wherein the Al(CRl a 2)nA2(CRl a 2)n linker is oxygen may be synthesized by methods known in the art, for example as shown in Scheme 32. The suitably substituted phenol XIV may be reacted with methyl N-(cyano)methanimidate to provide the 4-phenoxyimidazole XV. After selective protection of one of the imidazolyl nitrogens, the intermediate XVI can undergo alkylation reactions as described for the benzylimidazoles hereinabove. Scheme 33 illustrates an analogous series of reactions wherein the (CRlb2)pX(CRlt>2)p linker of the instant compounds is oxygen. Thus, a suitably substituted haloaryl alcohol, such as , is reacted with methyl N-(cyano)methanimidate to provide intermediate XVI. Intermediate XVI is then protected and, if desired to form a compound of a preferred embodiment, alkylated with a suitably protected benzyl. The intermediate XVII can then be coupled to a second aryl moiety by Suzuki chemistry to provide the instant compound. Compounds of the instant invention wherein the Al(CRl a 2)n 2(CRl a 2)n linker is a substituted methylene may be synthesized by the methods shown in Scheme 34. Thus, the N-protected imidazolyl iodide XVIII is reacted, under Grignard conditions with a suitably protected benzaldehyde to provide the alcohol XIX. Acylation, followed by the alkylation procedure illustrated in the Schemes above (in particular, Scheme 23) provides the instant compound XX. If other Rl substituents are desired, the acetyl moiety can be manipulated as illustrated in the Scheme. Grignard chemistry may also be employed to form a substituted alkyl linker between the biaryl and the preferred W (imidazolyl) as shown in Scheme 35. Similar substituent manipulation as shown in Scheme 34 may be performed on the fully functionalized compound which incoφorates an R lb hydroxyl moiety. Scheme 36 illustrates reactions wherein the moiety V - A 1 (CR 1 a 2 ) n A 2 (CR 1 - (CR 1 2 ) p -X incorporated in the compounds of the instant invention is represented by other than a substituted imidazole-containing group. Thus, the intermediates whose synthesis are illustrated in Schemes hereinabove and other biheteroaryl intermediates obtained commercially or readily synthesized, can be coupled with a variety of aldehydes. The aldehydes can be prepared by standard procedures, such as that described by O. P. Goel, U. Krolls, M. Stier and S. Kesten in Organic Syntheses. 1988, 67, 69-75, from the appropriate amino acid (Scheme 14). Grignard chemistry may be utilized, as shown in Scheme 36, to incoφorate the biaryl moiety. Thus, a suitably substituted biaryl Grignard reagent is reacted with an aldehyde to provide the C-alkylated instant compound XXI. Compound XXI can be deoxygenated by methods known in the art, such as a catalytic hydrogention, then deprotected with trifluoroacetic acid in methylene chloride to give the final compound XXII. The final product XXII may be isolated in the salt form, for example, as a trifluoroacetate, hydrochloride or acetate salt, among others. The product diamine XXII can further be selectively protected to obtain XXIII, which can subsequently be reductively alkylated with a second aldehyde to obtain XXIV. Removal of the protecting group, and conversion to cyclized products such as the dihydroimidazole XXV can be accomplished by literature procedures.

Thus, Scheme 38 illustrates the analogous series of arylheteroaryl alcohol forming reactions starting with the halogenated arylaldehyde. Scheme 39 illustrates the reaction wherein the "terminal" heteroaryl moiety is employed in the Suzuki coupling as the halogenated reactant. Such a coupling reaction is also compatible when one of the reactants incoφorates a suitably protected hydroxyl functionality as illustrated in Scheme 40. Negishi chemistry (Org.

Thus, a suitably substituted zinc bromide adduct may be coupled to a suitably substituted aryl halide in the presence of nickel (II) to provide the arylheteroaryl VII. The heteroaryl halide and the zinc bromide adduct may be selected based on the availability of the starting reagents. Scheme 42 illustrates the preparation of the suitably substituted arylheteroaryl methanol from the pyridyltoluene. Scheme 43 illustrates the preparation of the suitably substituted pyrazinylaryl methanol starting with alanine. As illustrated in Scheme 44, the sequence of coupling reactions may be modified such that the arylheteroaryl bond is formed last.

Addition of various nucleophiles to an imidazolyl aldehyde may also be employed to form a substituted alkyl linker between the arylheteroaryl and the preferred W (imidazolyl) as shown in Scheme 50. Thus a halogenated arylheteroaryl, such as 4-(3-pyridyl)bromo- benzene, may undergo metal halogen exchange followed by reaction with a suitably substituted imidazolyl aldehyde and acteylation to form the alcohol.

Scheme 57 illustrates the preparation of a suitably substituted 3-hydroxymethyl-5-phenyl pyridine which could also be utilized in the reaction with the protected imidazole as described in Scheme 53. An Alternative preparation of a suitably substituted 5- hydroxymethyl-2-phenyl pyridine is also illustrated. As illustrated in Scheme 58, the sequence of coupling reactions may be modified such that the aryl-heteroaryl bond is formed last.

The product diamine XXII can further be selectively protected to obtain XXIII, which can subsequently be reductively alkylated with a second aldehyde to obtain XXIV. Removal of the protecting group, and conversion to cyclized products such as the dihydroimidazole XXV can be accomplished by literature procedures. If the arylheteroaryl subunit reagent is reacted with an aldehyde which also has a protected hydroxyl group, such as XXVI in Scheme 66, the protecting groups can be subsequently removed to unmask the hydroxyl group. The alcohol can be oxidized under standard conditions to e.g. an aldehyde, which can then be reacted with a variety of organometallic reagents such as alkyl lithium reagents, to obtain secondary alcohols such as XXX. Incoφoration of other moieties via the appropriate aldehyde starting material may be performed as illustrated in Scheme 65-66 and the intermediates manipulated as illustrated above in Schemes 4-9.

R5, R6 and R8; although only one such R3, R6 or R8 is present in the intermediates and products of the schemes, it is understood that the reactions shown are also applicable when such aryl or heteroaryl moieties contain multiple substituents. The compounds referred to in the Synopsis of Schemes 67-78 by Roman numerals are numbered starting sequentially with I and ending with XX. These reactions may be employed in a linear sequence to provide the compounds of the invention or they may be used to synthesize fragments which are subsequently joined by the alkylation reactions described in the Schemes. The reactions described in the Schemes are illustrative only and are not meant to be limiting. Other reactions useful in the preparation of heteroaryl moieties are described in "Comprehensive Organic Chemistry, Volume 4: Heterocyclic Compounds" ed. P.G. Sammes, Oxford (1979) and references therein. Aryl-aryl coupling is generally described in "Comprehensive Organic Functional Group Transformations," Katritsky et al. eds., pp 472-473, Pergamon Press (1995). Synopsis of Schemes 67-78: The requisite intermediates are in some cases commercially available, or can be prepared according to literature procedures, for the most part. Schemes 67-78 illustrate synthesis of the instant biheteroaryl compound which incoφorate a preferred benzylimidazolyl sidechain. Thus, in Scheme 67, for example, a biheteroaryl intermediate that is not commercially available may be synthesized by methods known in the art. Thus, a suitably substituted pyridyl boronic acid I may be reacted under Suzuki coupling conditions (Pure Appl Chem., 63:419 (1991)) with a suitably substituted halogenated nicotinic acid, such as 4-bromo- nicotinic acid, to provide the biheteroaryl carboxylic acid II. The acid may be reduced and the triflate of the intermediate alcohol III may be formed in situ and coupled to a suitably substituted benzylimidazolyl IV to provide, after deprotection, the instant compound V. Schemes 68-71 illustrate other methods of synthesizing the key alcohol intermediates, which can then be processed as described in Scheme 67. Thus, Scheme 68 illustrates the analogous series of biheteroaryl alcohol forming reactions starting with the methyl nicotinate boronic acid and the "terminal" heteroaryl moiety employed in the Suzuki coupling as the halogenated reactant. Such a coupling reaction is also compatible when one of the reactants incoφorates a suitably protected hydroxyl functionality as illustrated in Scheme 69. Negishi chemistry (Org. Synth., 66:67 (1988)) may also be employed to form the biheteroaryl component of the instant compounds, as shown in Scheme 70. Thus, a suitably substituted zinc bromide adduct may be coupled to a suitably substituted heteroaryl halide in the presence of nickel (II) to provide the biheteroaryl VII. The heteroaryl halide and the zinc bromide adduct may be selected based on the availability of the starting reagents. Scheme 71 illustrates the preparation of the pyridylmethanol intermediate starting with the 3-methyl pyridine. As illustrated in Scheme 72, the sequence of coupling reactions may be modified such that the heteroaryl-heteroaryl bond is formed last. Thus, a suitably substituted imidazole may first be alkylated with a suitably substituted benzyl halide to provide intermediate VIII. Intermediate VIII can then undergo Suzuki type coupling to a suitably substituted pyridyl boronic acid. Scheme 73 illustrates synthesis of an instant compound wherein a non-hydrogen R^b is incoφorated in the instant compound. Thus, a readily available 4-substituted imidazole IX may be selectively iodinated to provide the 5-iodoimidazole X. That imidazole may then be protected and coupled to a suitably substituted benzyl moiety to provide intermediate XI. Intermediate XI can then undergo the alkylation reactions that were described hereinabove. Scheme 74 illustrates synthesis of instant compounds that incoφorate a preferred imidazolyl moiety connected to the biaryl via an alkyl amino, sulfonamide or amide linker. Thus, the 4-aminoalkyl- imidazole XII, wherein the primary amine is protected as the phthalimide, is selectively alkylated then deprotected to provide the amine XIII. The amine XIII may then react under conditions well known in the art with various activated biheteroaryl moieties to provide the instant compounds shown. Compounds of the instant invention wherein the Al(CRl2)n 2(CRl2)n linker is oxygen may be synthesized by methods known in the art, for example as shown in Scheme 75. The suitably substituted phenol XIV may be reacted with methyl N-(cyano)methanimidate to provide the 4-phenoxyimidazole XV. After selective protection of one of the imidazolyl nitrogens, the intermediate XVI can undergo alkylation reactions as described for the benzylimidazoles hereinabove. Scheme 76 illustrates an analogous series of reactions wherein the linker of the instant compounds is oxygen. Thus, a suitably substituted halopyridinol, such as 3-chloro- 2-pyridinol, is reacted with methyl N-(cyano)methanimidate to provide intermediate XVI. Intermediate XVI is then protected and, if desired to form a compound of a preferred embodiment, alkylated with a suitably protected benzyl. The intermediate XVII can then be coupled to a heteroaryl moiety by Suzuki chemistry to provide the instant compound. Compounds of the instant invention wherein the Al(CRl2)nA2(CRl2)n linker is a substituted methylene may be synthesized by the methods shown in Scheme 77. Thus, the N-protected imidazolyl iodide XVIII is reacted, under Grignard conditions with a suitably protected benzaldehyde to provide the alcohol XIX. Acylation, followed by the alkylation procedure illustrated in the Schemes above (in particular, Scheme 67) provides the instant compound XX. If other Rl substituent s are desired, the acetyl moiety can be manipulated as illustrated in the Scheme. Scheme 78 illustrates the use of halogenated 2-amino- pyrimidine in the preapration of compounds of the instant invention.

The reactions described in the Schemes are illustrative only and are not meant to be limiting. Other reactions useful in the preparation of heteroaryl moieties are described in "Comprehensive Organic Chemistry, Volume 4: Heterocyclic Compounds" ed. P.G. Sammes, Oxford (1979) and references therein. Synopsis of Schemes 79-88: The requisite intermediates are in some cases commercially available, or can be prepared according to literature procedures. Schemes 79-88 illustrate synthesis of the instant bicyclic compounds which incorporate a preferred benzylimidazolyl side chain. Thus, in Scheme 79, for example, a bicyclic intermediate that is not commercially available may be synthesized by methods known in the art. Thus, a suitably substituted pyridinone 1 may be reacted under coupling conditions with a suitably substituted iodobenzyl alcohol to provide the intermediate alcohol 2. The intermediate alcohol 2 may converted to the corresponding bromide 3. The bromide 3 may be coupled to a suitably substituted benzylimidazolyl 4 to provide, after deprotection, the instant compound 5. Schemes 80-82 illustrate methods of synthesizing related or analogous key alcohol intermediates, which can then be processed as described in Scheme 79. Thus, Scheme 80 illustrates pyridinonyl- pyridyl alcohol forming reactions starting with the suitably substituted iodonicotinate 6. Scheme 81 illustrates preparation of the intermediate alcohol 9 wherein the terminal lactam ring is saturated. Acylation of a suitably substituted 4-aminobenzyl alcohol 7 with a suitably substituted brominated acyl chloride provides the bisacylated intermediate 8. Closure of the lactam ring followed by saponifi- action of the remaining acyl group provides the intermediate alcohol. Preparation of the homologous saturated lactam 10 is illustrated in Scheme 82. Scheme 83 illustrates the synthesis of the alcohol intermediate 13 which incorporates a terminal pyrazinone moiety. Thus, the amide of a suitably substituted amino acid 11 is formed and reacted with glyoxal to form the pyrazine 12, which then undergoes the Ullmann coupling to form intermediate 13. Scheme 84 illustrates synthesis of an instant compound wherein a non-hydrogen R^b is incoφorated in the instant compound. Thus, a readily available 4-substituted imidazole 14 may be selectively iodinated to provide the 5-iodoimidazole 15. That imidazole may then be protected and coupled to a suitably substituted benzyl moiety to provide intermediate 16. Intermediate 16 can then undergo the alkylation reactions that were described hereinabove. Scheme 85 illustrates synthesis of instant compounds that incoφorate a preferred imidazolyl moiety connected to the bicyclic moiety via an alkyl amino, sulfonamide or amide linker. Thus, the 4-aminoalkylimidazole 17, wherein the primary amine is protected as the phthalimide, is selectively alkylated then deprotected to provide the amine 18. The amine 18 may then react under conditions well known in the art with various activated bicyclic moieties to provide the instant compounds shown. Compounds of the instant invention wherein the Al(CRl2)n 2(CRl2)n linker is oxygen may be synthesized by methods known in the art, for example as shown in Scheme 86. The suitably substituted phenol 19 may be reacted with methyl N-(cyano)methanimidate to provide the 4-phenoxyimidazole 20. After selective protection of one of the imidazolyl nitrogens, the intermediate 21 can undergo alkylation reactions as described for the benzylimidazoles hereinabove. Compounds of the instant invention wherein the A 1 (CR 12)n 2 (CR 12)n linker is a substituted methylene may be synthesized by the methods shown in Scheme 87. Thus, the N-protected imidazolyl iodide 22 is reacted, under Grignard conditions with a suitably protected benzaldehyde to provide the alcohol 23. Acylation, followed by the alkylation procedure illustrated in the Schemes above (in particular, Scheme 79) provides the instant compound 24. If other Rl substituents are desired, the acetyl moiety can be manipulated as illustrated in the Scheme. Scheme 88 illustrates incoφoration of an acetyl moiety as the linker of the instant compounds. Thus the readily available methylphenone 25 undergoes the Ullmann reaction and the acetyl is brominated to provide intermediate 26. Reaction with the imidazolyl reagent 4 provides, after deprotection, the instant compound 27.

Schemes 89-96 illustrate synthesis of the instant bicyclic compounds which incorporate a preferred benzylimidazolyl side- chain. Thus, in Scheme 89, for example, a bicyclic intermediate that is not commercially available may be synthesized by methods known in the art. Thus, a suitably substituted pyridinonyl alcohol 29 may be synthesized starting from the corresponding isonicotinate 28 according to procedures described by Boekelhiede and Lehn (J. Org. Chem., 26:428-430 (1961)). The alcohol is then protected and reacted under Ullmann coupling conditions with a suitably substituted phenyl iodide, to provide the intermediate bicyclic alcohol 30. The intermediate alcohol 30 may converted to the corresponding bromide 31. The bromide 31 may be coupled to a suitably substituted benzylimidazolyl 32 to provide, after deprotection, the instant compound 33. Schemes 90-92 illustrate methods of synthesizing related or alcohol intermediates, which can then be processed as described in Scheme 89. Thus, Scheme 90 illustrates preparation of a pyridyl- pyridinonyl alcohol and thienylpyridinonyl alcohol starting with the suitably substituted halogenated heterocycles. Scheme 91 illustrates preparation of the intermediate bromide 36 wherein the preferred pyridinone is replced by a saturated lactam. Acylation of a suitably substituted aniline 34 with a suitably substituted brominated acyl chloride provides the acylated intermediate 35. Closure of the lactam ring provides the intermediate alcohol, which is converted to the bromide as described above. Scheme 92 illustrates synthesis of an instant compound wherein a non-hydrogen R9b is incorporated in the instant compound. Thus, a readily available 4-substituted imidazole 37 may be selectively iodinated to provide the 5-iodoimidazole 38. That imidazole 38 may then be protected and coupled to a suitably substituted benzyl moiety to provide intermediate 39. Intermediate 39 can then undergo the alkylation reactions that were described hereinabove. Scheme 93 illustrates synthesis of instant compounds that incorporate a preferred imidazolyl moiety connected to the biaryl via an alkyl amino, sulfonamide or amide linker. Thus, the 4-aminoalkylimidazole 40, wherein the primary amine is protected as the phthalimide, is selectively alkylated then deprotected to provide the amine 41. The amine 41 may then react under conditions well known in the art with various activated arylheteroaryl moieties to provide the instant compounds shown. Compounds of the instant invention wherein the Al(CRl2)n 2(CRl2)n linker is oxygen may be synthesized by methods known in the art, for example as shown in Scheme 94. The suitably substituted phenol 42 may be reacted with methyl N-(cyano)methanimidate to provide the 4-phenoxyimidazole 43. After selective protection of one of the imidazolyl nitrogens, the intermediate 44 can undergo alkylation reactions as described for the benzylimidazoles hereinabove. Compounds of the instant invention wherein the Al(CRl2)n 2(CRl2)n linker is a substituted methylene may be synthesized by the methods shown in Scheme 95. Thus, the N- protected imidazolyl iodide 45 is reacted, under Grignard conditions with a suitably protected benzaldehyde to provide the alcohol 46. Acylation, followed by the alkylation procedure illustrated in the Schemes above (in particular, Scheme 89) provides the instant compound 47. If other Rl substituents are desired, the acetyl moiety can be manipulated as illustrated in the Scheme. Scheme 96 illustrates incorporation of an acetyl moiety as the linker of the instant compounds. Thus, the suitably substituted acetyl pyridine 48 is converted to the corresponding pyridinone and undergoes the Ullmann reaction with a suitably substituted phenyl iodide. The acetyl is then brominated to provide intermediate 49. Reaction with the imidazolyl reagent 32 provides, after deprotection, the instant compound 50. Scheme 97 illustrate reactions wherein the moiety - (CR 1 2 ) p -X. incorporated in the compounds of the instant invention is represented by other than a substituted imidazole-containing group. Thus, the intermediates whose synthesis are illustrated in the Schemes, and other pyridinonecarbocyclic and pyridinonehetero- cyclic intermediates obtained commercially or readily synthesized, can be coupled with a variety of aldehydes. The aldehydes can be prepared by standard procedures, such as that described by O. P. Goel, U. Krolls, M. Stier and S. Kesten in Organic Syntheses. 1988, 67, 69-75, from the appropriate amino acid. Knochel chemistry may be utilized, as shown in Scheme 97, to incorporate the arylpyridinone moiety. Thus, a suitably substituted 4-(bromo)- pyridine is converted to the corresponding pyridinone 51 as described above and the pyridinone is coupled to a suitably substituted phenyl iodide as previously described above. The resulting bromide 52 is treated with zinc(0) and the resulting zinc bromide reagent 53 is reacted with an aldehyde to provide the C- alkylated instant compound 54. Compound 54 can be deoxygenated by methods known in the art, such as a catalytic hydrogention, then deprotected with trifluoroacetic acid in methylene chloride to give the final compound 55. The compound 55 may be isolated in the salt form, for example, as a trifluoroacetate, hydrochloride or acetate salt, among others. The product diamine 55 can further be selectively protected to obtain 56, which can subsequently be reductively alkylated with a second aldehyde to obtain compound 57. Removal of the protecting group, and conversion to cyclized products such as the dihydroimidazole 58 can be accomplished by literature procedures.

Some key reactions utilized to form the aminodiphenyl moiety of the instant compounds are shown. These reactions may be employed in a linear sequence to provide the compounds of the invention or they may be used to synthesize fragments which are subsequently joined by the alkylation reactions described in the Reaction Schemes. Reaction Schemes A-P describe the preparation of appropriately substituted aniline intermediates that may be further functionalized by the methods described in Reaction Schemes Q-Y to provide the compounds of the instant invention. Reaction Schemes A-D illustrate use of Ullman reactions to provide diphenyl ethers, amines and sulf ides from readily available fully substituted phenols/thiophenols/anilines and aryl halides. In such syntheses, the desired amine moiety is typically masked as a nitro group which is subsequently reduced by techniques well known in the art. An alternative synthesis of the diphenyl ethers which employs para-nitro fluorobenzene is shown in Reaction Scheme E. Reaction Scheme F illustrates standard acid-amine coupling to provide the fully substituted N-phenylbenzamides. Reaction Scheme G illustrates formation of the aminomethyl spacer via a reductive amination of a suitably substituted benzaldehyde. Reaction Scheme H illustrates coupling of suitably substituted anilines with readily available phenylsulfonyl chlorides. Access to aminobenzophenones is illustrated in Reaction Scheme I, which also illustrates the reduction of the carbonyl to provide the unsubstituted methyl spacer. An alternative method of forming the benzophenone intermediates is illustrated in Reaction Scheme J. Also shown in Reaction Scheme J is reductive amination of the resulting carbonyl to provide the amine substituted methyl spacer. Another method of forming the benzophenone intermediates, illustrated in Reaction Scheme K, is a Stille reaction with an aryl stannane. Reaction Schemes L and M illustrate palladium mediated formation of olefin and acetylene spacer units. Reaction Scheme N illustrates formation of an appropriately substituted benzyl ether. Reaction Scheme P illustrates the use of the Claisen rearrangement to provide methyl spacers having substituents such as a vinyl group which can be further functionalized.

Thus, the aminodiphenyl subunit can be reductively alkylated with aldehydes such as l-trityl-4-carboxaldehyde or 1-trityl- 4-imidazolylacetaldehyde, to give products such as VIII (Reaction Scheme Q). The trityl protecting group can be removed from VIII to give IX, or alternatively, VIII can first be treated with an alkyl halide then subsequently deprotected to give the alkylated imidazole X. Alternatively, the aminomethylbenzamide subunit can be acylated or sulfonylated by standard techniques. The imidazole acetic acid XI can be converted to the acetate XIII by standard procedures, and XIII can be first reacted with an alkyl halide, then treated with refluxing methanol to provide the regiospecifically alkylated imidazole acetic acid ester XIV. Hydrolysis and reaction with the aminodiphenyl subunit in the presence of condensing reagents such as l-(3-dimethylaminopropyl)- 3-ethylcarbodiimide (EDC) leads to acylated products such as XV. Coupling reactions with other suitably substituted aldehydes may be performed as illustrated in Schemes 3 and 6-9 hereinabove. Reaction Scheme S illustrates a one pot synthesis of an instant compound wherein the N-terminus nitrogen is substituted with two different non-sulfhydryl-containing moieties. Thus, the aminodiphenyl subunit is treated with one equivalent of an appropriate aldehyde and, after the reductive adduct has been formed, the in situ intermediate is treated with an equivalent of a different aldehyde.

EXAMPLES Examples provided are intended to assist in a further understanding of the invention. Particular materials employed, species and conditions are intended to be further illustrative of the invention and not limitative of the reasonable scope thereof. The standard workup referred to in the examples refers to solvent extraction and washing the organic solution with 10% citric acid, 10% sodium bicarbonate and brine as appropriate. Solutions were dried over sodium sulfate and evaporated in vacuo on a rotary evaporator. EXAMPLE 1 (S)-l-(3-chlorophenyl)-4-[l-(4-cyanobenzyl)-imidazolylmethyl]-5-[2- (methanesulfonyl)ethyl1-2-piperazinone dihydrochloride Step A: l-triphenylmethyl-4-(hydroxymethyl)-imidazole To a solution of 4-(hydroxymethyl)imidazole hydrochloride (35.0 g, 260 mmol) in 250 mL of dry DMF at room temperature was added triethylamine (90.6 mL, 650 mmol). A white solid precipitated from the solution. Chlorotriphenylmethane (76.1 g, 273 mmol) in 500 mL of DMF was added dropwise. The reaction mixture was stirred for 20 hours, poured over ice, filtered, and washed with ice water. The resulting product was slurried with cold dioxane, filtered, and dried in vacuo to provide the titled product as a white solid which was sufficiently pure for use in the next step. Step B: l-triphenylmethyl-4-(acetoxymethyl)-imidazole Alcohol from Step A (260 mmol, prepared above) was suspended in 500 mL of pyridine. Acetic anhydride (74 mL, 780 mmol) was added dropwise, and the reaction was stirred for 48 hours during which it became homogeneous. The solution was poured into 2 L of EtOAc, washed with water (3 x 1 L), 5% aq. HCI soln. (2 x 1 L), sat. aq. NaHCθ3, and brine, then dried (Na2S04), filtered, and concentrated in vacuo to provide the crude product. The acetate was isolated as a white powder which was sufficiently pure for use in the next reaction. Step C: l-(4-cyanobenzyl)-5-(acetoxymethyl)-imidazole hydrobromide A solution of the product from Step B (85.8 g, 225 mmol) and α-bromo-/ tolunitrile (50.1 g, 232 mmol) in 500 mL of EtOAc was stirred at 60°C for 20 hours, during which a pale yellow precipitate formed. The reaction was cooled to room temperature and filtered to provide the solid imidazolium bromide salt. The filtrate was concentrated in vacuo to a volume 200 mL, reheated at 60°C for two hours, cooled to room temperature, and filtered again. The filtrate was concentrated in vacuo to a volume 100 mL, reheated at 60°C for another two hours, cooled to room temperature, and concentrated in vacuo to provide a pale yellow solid. All of the solid material was combined, dissolved in 500 mL of methanol, and warmed to 60°C. After two hours, the solution was reconcentrated in vacuo to provide a white solid which was triturated with hexane to remove soluble materials. Removal of residual solvents in vacuo provided the titled product hydrobromide as a white solid which was used in the next step without further purification. Step D: l-(4-cvanobenzyl)-5-(hvdroxymethyl)-imidazole To a solution of the acetate from Step C (50.4 g, 150 mmol) in 1.5 L of 3: 1 THF/water at 0 °C was added lithium hydroxide monohydrate (18.9 g, 450 mmol). After one hour, the reaction was concentrated in vacuo, diluted with EtOAc (3 L), and washed with water, sat. aq. NaHCθ3 and brine. The solution was then dried (Na2Sθ4), filtered, and concentrated in vacuo to provide the crude product as a pale yellow fluffy solid which was sufficiently pure for use in the next step without further purification. Step E: l-(4-cyanobenzyl)-5-imidazolecarboxaldehyde To a solution of the alcohol from Step D (21.5 g, 101 mmol) in 500 mL of DMSO at room temperature was added triethylamine (56 mL, 402 mmol), then Sθ3-pyridine complex (40.5 g, 254 mmol). After 45 minutes, the reaction was poured into 2.5 L of EtOAc, washed with water (4 x 1 L) and brine, dried (Na2S04), filtered, and concentrated in vacuo to provide the aldehyde as a white powder which was sufficiently pure for use in the next step without further purification. Step F: £S)-2-(terf-butoxycarbonylamino)-N-methoxy-N-methyl- 4-(methylthio)butanamide L-N-Boc-methionine (30.0 g, 0.120 mol), N, O-dimethyl- hydroxylamine hydrochloride (14.1 g, 0.144 mol), EDC hydrochloride (27.7 g, 0.144 mol) and HOBT (19.5 g, 0.144 mol) were stirred in dry DMF (300 mL) at 20°C under nitrogen. More N, O-dimethylhydroxyl- amine hydrochloride (2.3 g, 23 mmol) was added to obtain pH 7-8. The reaction was stirred overnight, the DMF distilled to half the original volume under high vacuum, and the residue partitioned between ethyl acetate and sat. NaHCθ3 soln. The organic phase was washed with saturated sodium bicarbonate, water, 10% citric acid, and brine, and dried with sodium sulfate. The solvent was removed in vacuo to give the title compound. Step G: (S)-2-(tgrt-butoxycarbonylamino)-4-(methylthio)butanal A suspension of lithium aluminum hydride (5.02 g, 0.132 mol) in ether (500 mL) was stirred at room temperature for one hour. The solution was cooled to -50°C under nitrogen, and a solution of the product from Step F (39.8 g, ca. 0.120 mol) in ether (200 mL) was added over 30 min, maintaining the temperature below -40°C. When the addition was complete, the reaction was warmed to 5°C, then recooled to -45°C. Analysis by tic revealed incomplete reaction. The solution was rewarmed to 5 °C, stirred for 30 minutes, then cooled to -50°C. A solution of potassium hydrogen sulfate (72 g, 0.529 mol) in 200 mL water was slowly added, maintaining the temperature below -20°C. The mixture was wasmed to 5°C, filtered through Celite, and concentrated in vacuo to provide the title aldehyde. Step H: (S)-2-(te^butoxycarbonylamino)-N-(3-chlorophenyl)- 4-(methylthio)butanamine To a solution of 3-chloroaniline (10.3 mL, 97.4 mmol), the product from Step G (23.9 g, 97.4 mmol), and acetic acid (27.8 mL, 487 mmol) in dichloroethane (250 mL) under nitrogen was added sodium triacetoxyborohydride (41.3 g, 195 mmol). The reaction was stirred overnight, then quenched with saturated sodium bicarbonate solution. The solution was diluted with CHCI3, and the organic phase was washed with water, 10% citric acid and brine. The solution was dried over sodium sulfate and concentrated in vacuo to provide the crude product (34.8 g) which was chromatographed on silica gel with 20% ethyl acetate in hexane to obtain the title compound . Step I: (S)-4-(tert-butoxycarbonyl)-l-(3-chlorophenyl)-5-[2- (methylthio)ethyl1piperazin-2-one A solution of the product from Step H (22.0 g, 63.8 mmol) in ethyl acetate (150 mL) was vigorously stirred at 0°C with saturated sodium bicarbonate (150 mL).

Step G: Preparation of (R)-l-(3-chlorophenyl)-4-[l-(4- cyanobenzyl)-5-imidazolylmethyl]-5-[2- (ethanesulfonyl)methyl1-2-piperazinone dihydrochloride To a solution of the Boc-protected piperazinone from Step F (224 mg, 0.538 mmol) in 5 mL of dichloromethane at 0°C was added 2.5 mL of trifluoroacetic acid (TFA). After 45 minutes, the reaction was concentrated in vacuo, then azeotroped with benzene to remove the excess TFA. The residue was taken up in 4 mL of 1,2-dichloroethane and cooled to 0°C. To this solution was added 4 A powdered molecular sieves (340 mg), followed by sodium triacetoxyborohydride (285 mg, 1.34 mmol) and several drops of triethylamine to achieve pH = 6. The imidazole carboxaldehyde from Step E of Example 42 (125 mg, 0.592 mmol) was added, and the reaction was stirred at 0°C. After 2 days, the reaction was poured into EtOAc, washed with dilute aq. NaHCθ3, and brine, dried (Na2Sθ4), filtered, and concentrated in vacuo. The crude product was taken up in methanol and injected onto a preparative HPLC column and purified with a mixed gradient of 15%-50% acetonitrile/ 0.1% TFA; 85%-50% 0.1% aqueous TFA over 60 minutes. After concentration in vacuo, the resultant product was partitioned between dichloromethane and aq. NaHCθ3 soln., and the aqueous phase was extracted with CH2CI2. The organic solution was washed with brine, dried (Na2S04), filtered, and concentrated to dryness to provide the product free base, which was taken up in CH2CI2 and treated with 2.1 equivalents of 1 M HCl/ether solution. After concentrated in vacuo, the product dihydrochloride was isolated as a white powder. BIOLOGICAL ASSAYS. The ability of compounds of the present invention to inhibit cancer can be demonstrated using the following assays. In vitro inhibition of farnesyl-protein transferase Transferase Assays. Isoprenyl-protein transferase activity assays were carried out at 30°C unless noted otherwise. A typical reaction contained (in a final volume of 50 μL): [ 3 H]farnesyl diphosphate or [ 3 H]geranylgeranyl diphosphate, Ras protein , 50 mM HEPES, pH 7.5, 5 mM MgCl 2 , 5 mM dithiothreitol and isoprenyl- protein transferase. The FPTase employed in the assay was prepared by recombinant expression as described in Omer, C.A., Krai, A.M., Diehl, R.E., Prendergast, G.C., Powers, S., Allen, CM., Gibbs, J.B. and Kohl, N.E. (1993) Biochemistry 32:5167-5176. The geranylgeranyl-protein transferase-type I employed in the assay was prepared as described in U.S. Pat. No. 5,470,832, incorporated by reference. After thermally pre-equilibrating the assay mixture in the absence of enzyme, reactions were initiated by the addition of isoprenyl-protein transferase and stopped at timed intervals (typically 15 min) by the addition of 1 M HCI in ethanol (1 mL). The quenched reactions were allowed to stand for 15 m (to complete the precipitation process). After adding 2 mL of 100% ethanol, the reactions were vacuum-filtered through Whatman GF/C filters. Filters were washed four times with 2 mL aliquots of 100% ethanol, mixed with scintillation fluid (10 mL) and then counted in a Beckman LS3801 scintillation counter . For inhibition studies, assays were run as described above, except inhibitors were prepared as concentrated solutions in 100% dimethyl sulfoxide and then diluted 20-fold into the enzyme assay mixture. IC 50 values were determined with both transferase substrates near Ku concentrations. Nonsaturating substrate conditions for inhibitor IC50 determinations were as follows: FTase, 650 nM Ras- CVLS, 100 nM farnesyl diphosphate; GGPTase-I, 500 nM Ras-CAIL, 100 nM geranylgeranyl diphosphate. In vivo ras prenylation assay The cell lines used in this assay consist of either Ratl or NIH3T3 cells transformed by either viral Ha-ra-s; an N-ras chimeric gene in which the C-terminal hypervariable region of v-Ha-ra-s was substituted with the corresponding region from the N-ras gene; or ras-CVLL, a v-Ha-rø-s mutant in which the C-terminal exon encodes leucine instead of serine, making the encoded protein a substrate for geranylgeranylation by GGPTase I. The assay can also be performed using cell lines transformed with human Ha-ra-s, N-ras or Ki4B-ras. The assay is performed essentially as described in DeClue, J.E. et al., Cancer Research 51:712-717, (1991). Cells in 10 cm dishes at 50-75% confluency are treated with the test compound(s) (final concentration of solvent, methanol or dimethyl sulfoxide, is 0.1%). After 4 hours at 37°C, the cells are labelled in 3 ml methionine-free DMEM supplemented with 10% regular DMEM, 2% fetal bovine serum, 400 μCi[35S]methionine (1000 Ci/mmol) and test compound(s). Cells treated with lovastatin, a compound that blocks Ras processing in cells by inhibiting the rate-limiting step in the isoprenoid biosynthetic pathway (Hancock, J.F. et al. Cell, 57:1167 (1989); DeClue, J.E. et al. Cancer Res., 51:712 (1991); Sinensky, M. et al. J. Biol Chem., 265:19937 (1990)), serve as a positive control in this assay. After an additional 20 hours, the cells are lysed in 1 ml lysis buffer (1% NP40/20 mM HEPES, pH 7.5/5 mM MgCl2/lmM DTT/10 mg/ml aprotinen/2 mg/ml leupeptin/2 mg/ml antipain/0.5 mM PMSF) and the lysates cleared by centrifugation at 100,000 x g for 45 min. Alternatively, four hours after the additon of the labelling media, the media is removed, the cells washed, and 3 ml of media containing the same or a different test compound added. Following an additional 16 hour incubation, the lysis is carried out as above. Aliquots of lysates containing equal numbers of acid-precipitable counts are bought to 1 ml with IP buffer (lysis buffer lacking DTT) and immunoprecipitated with the ras-specific monoclonal antibody Y13-259 (Furth, M.E. et al., J. Virol. 43:294-304, (1982)). Following a 2 hour antibody incubation at 4°C, 200 μl of a 25% suspension of protein A-Sepharose coated with rabbit anti rat IgG is added for 45 min. The immunoprecipitates are washed four times with IP buffer (20 nM HEPES, pH 7.5/1 mM EDTA/1% Triton X- 100.0.5% deoxycholate/0.1%/SDS/0.1 M NaCl) boiled in SDS-PAGE sample buffer and loaded on 13% acrylamide gels. When the dye front reached the bottom, the gel is fixed, soaked in Enlightening, dried and auto- radiographed. The intensities of the bands corresponding to prenylated and nonprenylated Ras proteins are compared to determine the percent inhibition of prenyl transfer to protein. In vivo growth inhibition of Ras transformed cells assay To determine the biological consequences of FPTase inhibition, the effect of the compounds of the instant invention on the anchorage-independent growth of Ratl cells transformed with either a v-ras, v-raf, or v-mos oncogene is tested. Cell lines transformed with human Ha-ras, N-ras or Ki4B-ras can also be utilized. Cells transformed by v-Raf and v-Mos may be included in the analysis to evaluate the specificity of instant compounds for Ras-induced cell transformation. Rat 1 cells transformed with either v-ras, v-raf, or v-mos are seeded at a density of 1 x 10 4 cells per plate (35 mm in diameter) in a 0.3% top agarose layer in medium A (Dulbecco's modified Eagle's medium supplemented with 10% fetal bovine serum) over a bottom agarose layer (0.6%). Both layers contain 0.1% methanol or an appropriate concentration of the instant compound (dissolved in methanol at 1000 times the final concentration used in the assay). The cells are fed twice weekly with 0.5 ml of medium A containing 0.1% methanol or the concentration of the instant compound. Photomicrographs are taken approximately 16 days after the cultures are seeded and comparisons are made. In addition, the activity of the compounds of the present invention for treating cancer and/or inhibiting tumor growth is confirmed utilizing the nude mouse tumor xenograft assay described in Kohl et al., PNAS 91 (1994) 9141-45. In vitro growth inhibition of human tumor cells assays Cancer cells (MCF-7, MDA-468, T47D, MDA-231, SkOv3, A549, SkBr3,PC3, LNCaP or DU-145) are seeded in 6 well clusters at 10,000 or 20,000 cells per well.

The monolayer of cells is then separated from the media and washed 4 times with PBS. The cells are trypsinized and counted with a Coulter counter. 20,000 cells are replated on 6 well plates in 0.35% agar over a 0.7% agar layer, both layers which contain vehicle only, 0.2 μM, 2 μM or 20 μM of a farnesyl-protein transferase inhibitor. The cells are fed and treated with the FTI, or vehicle only, twice weekly. At the end of twelve days incubation the cells are scored manually from duplicate wells. Protocol D-2 The cells are placed in growth media containing a antineoplastic agent for four (4) hours. The monolayer of cells is then separated from the media and washed 4 times with PBS. The cells are trypsinized and counted with a Coulter counter. 10,000 cells are replated on 12 well plates in the standard RPMI media described above which contain vehicle only, 0.2 μM or 2 μM of a farnesyl-protein transferase inhibitor. The cells are fed and treated with the FTI, or vehicle only, twice weekly and at those times the colonies are scored manually from duplicate wells. At the end of seven days incubation the cells are scored manually from duplicate wells. Protocol E-l Protocol is similar to Protocol A except that the cells are plated at 4,000 to 10,000 cells per well. At the end of 5 days incubation with the FTI, 1 μL of a 5mg/ml atock of MTT () was added and the cells were incubated an additional 4 hours. The media was then removed and the cells were solubilized with 1 ml isopropanol for 2-3 minutes. The optical density of the cells was then read at 570nm wavelength. Protocol E-2 Protocol is similar to Protocol B except that the cells are plated at 4,000 to 10,000 cells per well. At the end of 5 days incubation with the FTI, 1 μL of a 5mg/ml atock of MTT () was added and the cells were incubated an additional 4 hours. The media was then removed and the cells were solubilized with 1 ml isopropanol for 2-3 minutes. The optical density of the cells was then read at 570nm wavelength. Protocol E-3 Protocol is similar to Protocol B except that the cells are plated at 4,000 to 10,000 cells per well. At the end of 5 days incubation with the FTI and the antineoplastic agent, 1 μL of a 5mg/ml atock of MTT () was added and the cells were incubated an additional 4 hours. The media was then removed and the cells were solubilized with 1 ml isopropanol for 2-3 minutes. The optical density of the cells was then read at 570nm wavelength. In vitro cell cycle assay Cancer cells (MCF-7, MDA-468 or DU-145) are seeded in a 10 cm dish at 1,000,000 cells per dish. After one day in growth media, the cells are exposed to various concentrations of a antineoplastic agent along with vehicle (PBS) or lμM FTI in the vehicle. After 24 hours of exposure to the combination or antineoplastic agent, the cells are trypsinized and stained with ethidium bromide. The stained nucleii are analyzed by flow cytometry for evaluation of the DNA content. In vivo tumor growth inhibition assay (nude mouse) Rodent fibroblasts transformed with oncogenically mutated human Ha- ras or Ki-ras (10 6 cells/animal in 1 ml of DMEM salts) are injected subcutaneously into the left flank of 8-12 week old female nude mice (Harlan) on day 0. The mice in each oncogene group are randomly assigned to a vehicle, compound or combination treatment group. Animals are dosed subcutaneously starting on day 1 and daily for the duration of the experiment. Alternatively, the farnesyl-protein transferase inhibitor may be administered by a continuous infusion pump. Compound, compound combination or vehicle is delivered in a total volume of 0.1 ml. Tumors are excised and weighed when all of the vehicle-treated animals exhibited lesions of 0.5 - 1.0 cm in diameter, typically 11-15 days after the cells were injected. The average weight of the tumors in each treatment group for each cell line is calculated. The following dosage groups are utilized to determine the efficacy of the combination of the farnesyl-protein transferase inhibitor (FTI) and antineoplastic agent (agent): Group O Vehicle controls Group A: FTI at maximum no effect dose Group B: FTI at minimal efficacy dose Group C: agent at maximal no effect dose Group D: agent at minimal efficacy dose Group E: A + C Group F: A + D Group G: B + C Group H: B + D Additional doses of FTI and agent can be selected as needed.
