Abstract: The present invention is directed to compounds which inhibit farnesyl-protein transferase (FTase) and the farnesylation of the oncogene protein Ras. The invention is further directed to chemotherapeutic compositions containing the compounds of this invention and methods for inhibiting farnesyl-protein transferase and the farnesylation of the oncogene protein Ras.

Description: TITLE OF THE INVENTION INHIBITORS OF FARNESYL-PROTEIN TRANSFERASE BACKGROUND OF THE INVENTION The Ras proteins (Ha-Ras, Ki4a-Ras, Ki4b-Ras and N-Ras) are 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. 2:851 -891 (1993)). Mutated ras genes ( ά-ras, Ki a-ras, Ki4b-ras and N-ras) 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. 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 "Cys-Aaa^-Aaa^-Xaa" box (Cys is cysteine, Aaa is an aliphatic amino acid, the Xaa is any amino acid) (Willumsen et al.. Nature _?/0:583-586 ( 1984)). Depend¬ ing on the specific sequence, this motif serves as a signal sequence for the enzymes famesyl-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)). The Ras protein is one of several proteins that are known to undergo post-translational famesylation. Other famesylated proteins include the Ras-related GTP- binding proteins such as Rho, 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 famesylated. James, et al., have also suggested that there are famesylated proteins of unknown structure and function in addition to those listed above. Inhibition of famesyl-protein transferase has been shown to block the growth of Ras-transformed cells in soft agar and to modify other aspects of their transformed phenotype. It has also been demonstrated that certain inhibitors of famesyl-protein transferase selectively block the processing of the 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 famesyl-protein transferase blocks the growth of / -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 ras transgenic mice (N.E. Kohl et al., Nature Medicine, 1 :792-797 (1995). Indirect inhibition of famesyl-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 a I.. Science 245:319 (1989)). These drugs inhibit HMG-CoA reductase, the rate limiting enzyme for the production of polyisoprenoids including famesyl pyrophosphate. Famesyl-protein transferase utilizes famesyl pyrophosphate to covalently modify the Cys thiol group of the Ras CAAX box with a famesyl group (Reiss et al., Cell, 62:81 -88 (1990); Schaber et al. . Biol. Chem., 265: 14701- 14704 ( 1990); Schafer et al., Science, 249: 1 133- 1 139 (1990); Manne et al., Proc. Natl. Acad. Sci USA. 57:7541-7545 (1990)). Inhibition of famesyl pyrophosphate biosynthesis by inhibiting HMG-CoA reductase blocks Ras membrane localization in cultured cells. However, direct inhibition of famesyl- 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. Inhibitors of famesyl-protein transferase (FPTase) have been described in four general classes (S. Graham, Expert Opinion Ther. Patents, (1995) 5: 1269-1285). The first are analogs of famesyl diphosphate (FPP), while a second class of inhibitors is related to the protein substrates (e.g., Ras) for the enzyme. Bisubstrate inhibitors and inhibitors of famesyl-protein transferase that are non-competitive with the substrates have also been described. 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 prenyl- ation. (Schaber et al., ibid; Reiss et. al., ibid; Reiss et al.. PNAS, 55:732-736 (1991 )). Such inhibitors may inhibit protein prenylation while serving as alternate substrates for the famesyl-protein trans¬ ferase 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., J. Med. Chem., 37, 725 (1994)). In general, deletion of the thiol from a CAAX derivative has been shown to dramatically reduce the inhibitory potency of the compound. However, the thiol group potentially places limitations on the therapeutic application of FPTase inhibitors with respect to pharmacokinetics, pharmacodynamics and toxicity. Therefore, a functional replacement for the thiol is desirable. It has recently been disclosed that certain tricyclic compounds which optionally incorporate a piperidine moiety are inhibitors of FPTase (WO 95/10514, WO 95/10515 and WO 95/10516). Imidazole-containing inhibitors of famesyl protein transferase have also been disclosed (WO 95/09001 and EP 0 675 1 12 Al ). It has recently been reported that famesyl-protein transferase inhibitors are inhibitors of proliferation of vascular smooth muscle cells and are therefore useful in the prevention and therapy of arteriosclerosis and diabetic disturbance of blood vessels (JP H7- 1 12930). It is, therefore, an object of this invention to develop low molecular weight compounds that will inhibit famesyl-protein transferase and thus, the post-translational famesylation of proteins. It is a further object of this invention to develop chemotherapeutic compositions containing the compounds of this invention and methods for producing the compounds of this invention.

The pharmaceutically acceptable salts of the compounds of this invention include the conventional non-toxic salts of the compounds of this invention as formed, e.g., from non-toxic inorganic or organic acids. For example, such conventional 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, maleic, hydroxymaleic, phenylacetic, glutamic, benzoic, salicylic, sulfanilic, 2-acetoxy-benzoic, fumaric, toluenesulfonic, methanesulf onic, ethane disulfonic. oxalic, isethionic, trifluoroacetic and the like. 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 either by ion exchange chroma-tography or 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. Reactions used to generate the compounds of this invention are prepared by employing reactions as shown in the Schemes 1-24, 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^ and R^. as shown in the Schemes, represent the substituents R^, R , R5, R6a, R6b. R6C, R6d an d R8- although only one such R 6 or R s 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. 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. 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 1-24: The requisite intermediates are in some cases commercially available, or can be prepared according to literature procedures, for the most part. Schemes 1 - 14 illustrate synthesis of the instant diheteroaryl compound which incorporate a preferred benzylimidazolyl sidechain. Thus, in Scheme 1 , for example, the commercially available dithienyl- carboxylic acid I may be reduced. The triflate of the intermediate alcohol II may be formed in situ and coupled to a suitably substituted benzylimidazolyl III to provide, after deprotection, the instant compound IV. Those biheteroaryl intermediates that are not commercially available may be synthesized by methods known in the art as well as those reactions illustrated in Schemes 2-6. Thus, as illustrated in Scheme 2 a thienyl boronic acid V may be reacted under Suzuki coupling conditions (Pure Appl. Chem., 63:419 (1991 )) with a suitably substituted halogenated heteroaryl moiety, such as 2-bromo, to provide the biheteroaryl carboxylic acid VI, which can then be processed as described in Scheme 1. Scheme 3 illustrates the analogous series of reactions starting with the halogenated heteroarylaldehyde. Scheme 4 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 incorporates a suitably protected hydroxyl functionality as illustrated in Scheme 5. Negishi chemistry (Org. Synth., 66:67 (1988)) may also be employed to form the biheteroaryl component of the instant compounds, as shown in Scheme 6. Thus, a zinc bromide adduct, such as 3-thienyl zinc bromide, 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. As illustrated in Scheme 7, 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 heteroarylmethyl halide to provide intermediate VIII. Intermediate VIII can then undergo Suzuki type coupling to a suitably substituted heteroaryl boronic acid. Scheme 8 illustrates the synthesis of a thiazole containing instant compound from the acyclic precursors. Similar strategies may be utilized to prepare other bisheteroatom moieties. Scheme 9 illustrates synthesis of an instant compound wherein a non-hydrogen R9b j s 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 10 illustrates synthesis of instant compounds that incorporate a preferred imidazolyl moiety connected to the biheteroaryl via an alkyl amino, sulfonamide or amide linker. Thus, the 4-aminoalkylimidazole 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 (CR l 2)nA 2 (CR l2)n linker is oxygen may be synthesized by methods known in the art, for example as shown in Scheme 1 1. 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 12 illustrates an analogous series of reactions wherein the (CR 2)pX(CR 2)p linker of the instant compounds is oxygen. Thus, a suitably substituted haloheteroaryl 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 heteroaryl moiety by Suzuki chemistry to provide the instant compound. Compounds of the instant invention wherein the Al (CRl2)nA (CRl 2)n linker is a substituted methylene may be synthesized by the methods shown in Scheme 13. 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 1 ) provides the instant compound XX. If other R 1 substituents are desired, the acetyl moiety can be manipulated as illustrated in the Scheme. Addition of various nucleophiles to an imidazolyl aldehyde may also be employed to form a substituted alkyl linker between the biheteroaryl moiety and the preferred W (imidazolyl) as shown in Scheme 14. Thus a bishalogenated five membered heteroaryl, such as 2,4-dibromothiophene, may undergo metal halogen exchange followed by reaction with a suitably substituted imidazolyl aldehyde and acteylation to form a regioisomeric mixture of the acetyl intermediates. The halogenated regioisomeric mixture may be chromatographically separated at this stage, if convenient. Suzuki coupling with a suitably substituted 5-membered heteroaryl boronic acid affords the instant acetoxy compound, which can be treated with lithium hydroxide to remove the acetyl group. Then, similar substituent manipulation as shown in Scheme 13 may be performed on a fully functionalized compound which incorporates an R 2 hydroxyl moiety. 45 SCHEME 1 Tr °C, CH 3 OH SCHEME 2 SCHEME 3 O aBH 4 CT/US97/06259 -47 - SCHEME 4 5 SCHEME 5 SCHEME 5 (continued) SCHEME 6 SCHEME 7 Pd(PPh 3 ) 4 US97/06259 - 51 - SCHEME 8 SCHEME 8 (continued) SCHEME 9 H H IX Tr SCHEME 10 T/US97/06259 -55- SCHEME 11 H Tr XV XVI /TX- NC XVI NC ^ SCHEME 12 H SCHEME 13 Tr SCHEME 13 (continued) SCHEME 14 Pd(PPh 3 ) 4 Schemes 15-24 illustrate reactions wherein the moiety V - A 1 (CR 1 2 ) n A 2 (CR - (CR 2 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 15). Metal halogen exchange chemistry (Scheme 14) may be employed when manipulating the aldehydes. Alternatively, Grignard chemistry may be utilized, as shown in Scheme 15. Thus, Suzuki coupling provides, for example, the pyrrole containing biheteroaryl XXI. Reaction of the intermediate XXI with a Grignard reagent provides the N-pyrrylmagnesium derivative XXIa, which is then reacted with an aldehyde to provide the C-alkylated instant compound XXII. The product XXII 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 XXIIa. 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. Scheme 16 illustrates the use of in situ formation of a lithium anion of a suitably substituted N-alkyl pyrrole to provide the C-alkylated compound of the instant invention. If the biheteroaryl subunit is reductively alkylated with an aldehyde which also has a protected hydroxyl group, such as XXVI in Reaction Scheme 17, the protecting groups can be subsequently removed to unmask the hydroxyl group (Reaction Schemes 17, 18). The alcohol can be oxidized under standard conditions to e. . an aldehyde, which can then be reacted with a variety of organometallic reagents such as Grignard reagents, to obtain secondary alcohols such as XXX. In addition, the fully deprotected amino alcohol XXXI can be reductively alkylated (under conditions described previously) with a variety of aldehydes to obtain secondary amines, such as XXXII (Reaction Scheme 18), or tertiary amines. The Boc protected amino alcohol XXVIII can also be utilized to synthesize 2-aziridinylrnethylbiheteroaryl such as XXXIII (Reaction Scheme 19). Treating XXVIII with l , l '-sulfonyldiimidazole and sodium hydride in a solvent such as dimethylformamide led to the formation of aziridine XXXIII . The aziridine is reacted with a nucleophile, such as a thiol, in the presence of base to yield the ring- opened product XXXIV . In addition, the biheteroaryl subunit can be reacted with aldehydes derived from amino acids such as O-alkylated tyrosines, according to standard procedures, to obtain compounds such as XL, as shown in Reaction Scheme 20. When R' is an aryl group. XL can first be hydrogenated to unmask the phenol, and the amine group deprotected with acid to produce XLI. Alternatively, the amine protecting group in XL can be removed, and O-alkylated phenolic amines such as XLII produced. Schemes 21 -24 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.

These compounds may be administered to patients for use in the treatment of cancer. Examples of the type of cancer which may be treated with the compounds of this invention include, but are not limited to. colorectal carcinoma, exocrine pancreatic carcinoma, myeloid leukemias and neurological tumors. Such tumors may arise by mutations in the ras genes themselves, mutations in the proteins that can regulate Ras activity (i.e., neurofibromin (NF- 1 ), neu, scr, abl , lck, fyn) or by other mechanisms. The compounds of the instant invention inhibit famesyl- protein transferase and the famesylation of the oncogene protein Ras. The instant compounds may also inhibit tumor angiogenesis, thereby affecting the growth of tumors (J. Rak et al. Cancer Research, 55:4575-4580 ( 1995)). Such anti-angiogenesis properties of the instant compounds may also be useful in the treatment of certain forms of blindness related to retinal vascularization. The compounds of this invention are 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 compounds of the invention to a mammal in need of such treatment. For example, a component of NF- 1 is a benign proliferative disorder. The instant compounds may also be useful in the treatment of certain viral , infections, in particular in the treatment of hepatitis delta and related viruses (J.S. Glenn et al. Science, 256: 13 1 - 1 33 ( 1992). The compounds of the instant invention are 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 compounds may also be useful in the treatment and prevention of polycystic kidney disease (D.L. Schaffner et al.

The compounds of this invention may be administered to mammals, preferably humans, either alone or, preferably, 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 compound according to this invention, the selected compound 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 com starch. When aqueous suspensions are required for oral use, the active ingredient is combined with emulsifying and suspending 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 compounds 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. For example, the instant compounds may be useful in combination with known anti-cancer and cytotoxic agents. Similarly, the instant compounds may be useful in combination with agents that are effective in the treatment and prevention of NF-1 , re tinosis, polycystic kidney disease, infections of hepatitis delta and related viruses and fungal infections. If formulated as a fixed dose, such combination products employ the compounds of this invention within the dosage range described below and the other pharmaceutically active agent(s) within its approved dosage range. Compounds of the instant invention may alternatively be used sequentially with known pharmaceutically acceptable agent(s) when a combination formulation is inappropriate. The present invention also encompasses a pharmaceutical composition useful in the treatment of cancer, comprising the administration of a therapeutically effective amount of the compounds 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 pharmacolo- gically 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. As used herein, the term "composition" is intended to encompass a product comprising the specified ingredients in the specific amounts, as well as any product which results, directly or indirectly, from combination of the specific ingredients in the specified amounts. When a compound 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 compound is administered to a mammal undergoing treatment for cancer. Administration occurs in an amount 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. The compounds of the instant invention are also useful as a component in an assay to rapidly determine the presence and quantity of famesyl-protein transferase (FPTase) in a composition. Thus the composition to be tested may be divided and the two portions contacted with mixtures which comprise a known substrate of FPTase (for example a tetrapeptide having a cysteine at the amine terminus) and famesyl pyrophosphate and, in one of the mixtures, a compound of the instant invention. After the assay mixtures are incubated for an sufficient period of time, well known in the art, to allow the FPTase to famesylate the substrate, the chemical content of the assay mixtures may be determined by well known immuno- logical, radiochemical or chromatographic techniques. Because the compounds of the instant invention are selective inhibitors of FPTase, absence or quantitative reduction of the amount of substrate in the assay mixture without the compound of the instant invention relative to the presence of the unchanged substrate in the assay containing the instant compound is indicative of the presence of FPTase in the composition to be tested. It would be readily apparent to one of ordinary skill in the art that such an assay as described above would be useful in identifying tissue samples which contain famesyl-protein transferase and quantitat- ing the enzyme. Thus, potent inhibitor compounds of the instant invention may be used in an active site titration assay to determine the quantity of enzyme in the sample. A series of samples composed of aliquots of a tissue extract containing an unknown amount of famesyl- protein transferase, an excess amount of a known substrate of FPTase (for example a tetrapeptide having a cysteine at the amine terminus) and famesyl pyrophosphate are incubated for an appropriate period of time in the presence of varying concentrations of a compound of the instant invention. The concentration of a sufficiently potent inhibitor (i.e.. one that has a Ki substantially smaller than the concentration of enzyme in the assay vessel) required to inhibit the enzymatic activity of the sample by 50% is approximately equal to half of the concentration of the enzyme in that particular sample.

EXAMPLE 3 In vitro inhibition of ras famesyl transferase Assays of famesyl-protein transferase. Partially purified bovine FPTase and Ras peptides (Ras-CVLS, Ras-CVIM and Ras-CAIL) were prepared as described by Schaber et al., J. Biol. Chem. 265:14701 - 14704 ( 1990), Pompliano, et aL, Biochemistry 31 :3800 ( 1992) and Gibbs et aL, PNAS U.S.A. 86:6630-6634 (1989), respectively. Bovine FPTase was assayed in a volume of 100 μl containing 100 mM N-(2- hydroxy ethyl) piperazine-/V'-(2-ethane sulfonic acid) (HEPES), pH 7.4, 5 mM MgCl2, 5 mM dithiothreitol (DTT), 100 mM f^H] -famesyl diphosphate ([^Hl-FPP; 740 CBq/mmol, New England Nuclear), 650 nM Ras-CVLS and 10 μg/ml FPTase at 31 °C for 60 min. Reactions were initiated with FPTase and stopped with 1 ml of 1.0 M HCL in ethanol. Precipitates were collected onto filter-mats using a TomTec Mach II cell harvestor, washed with 100% ethanol, dried and counted in an LKB β-plate counter. The assay was linear with respect to both substrates, FPTase levels and time; less than 10% of the HJ-FPP was utilized during the reaction period. Purified compounds were dissolved in 100% dimethyl sulfoxide (DMSO) and were diluted 20-fold into the assay. Percentage inhibition is measured by the amount of incorpora¬ tion of radioactivity in the presence of the test compound when compared to the amount of incorporation in the absence of the test compound. Human FPTase was prepared as described by Omer et al.. Biochemistry 32: 167-5176 (1993). Human FPTase activity was assayed as described above with the exception that 0.1 % (w/v) polyethylene glycol 20,000, 10 μM ZnC and lOO nM Ras-CVIM were added to the reaction mixture. Reactions were performed for 30 min.. stopped with 100 μl of 30% (v/v) trichloroacetic acid (TCA) in ethanol and processed as described above for the bovine enzyme. The compounds of the instant invention are tested for inhibitory activity against human FPTase by the assay described above. EXAMPLE 4 In vivo ras famesylation assay The cell line used in this assay is a v-ras line derived from either Ratl or NIH3T3 cells, which expressed viral Ha-ras p21. 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 (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 supple- meted with 10% regular DMEM, 2% fetal bovine serum and 400 mCi[ 35s]methionine ( 1000 Ci/mmol). 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. 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 Y 13-259 (Furth, M.E. et aL, J. Virol. 43:294-304, (1982)). Following a 2 hour antibody incubation at 4°C, 200 ml 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 autoradiographed. The intensities of the bands corresponding to famesylated and nonfamesylated ras proteins are compared to determine the percent inhibition of famesyl transfer to protein. EXAMPLE 5 In vivo growth inhibition 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. Cells transformed by v-Raf and v-Mos maybe 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 16 days after the cultures are seeded and comparisons are made.
