Description: ANTICANCER COMPOUND AND ENANTIOMER SEPARATION METHOD USEFUL FOR SYNTHESIZING SAID COMPOUND Background of the Invention This invention relates to a compound that can be used in the treatment of hyperproliferative disease, such as cancer, in mammals. This invention also relates to a method of using this compound, namely (+)-6-[amino-(6-chloro-pyridin-3-yl)-(3-methyl-3H- imidazol-4-yl)-methyl]-4-(3-chloro-phenyl)-1-cyclopropylmethyl-1 H-quinolin-2-one, in the treatment of hyperproliferative disease in mammals, especially humans, and to pharmaceutical compositions containing these enantiomers. This invention further relates to a method of separating enantiomers in a racemic mixture from one another, which method can be utilized to obtain the aforementioned compound of the invention. Oncogenes frequently encode protein components of signal transduction pathways which lead to stimulation of cell growth and mitogenesis. Oncogene expression in cultured cells leads to cellular transformation, characterized by the ability .of cells to,grow in soft agar and the growth of cells as dense foci lacking the contact inhibition exhibited by non- transformed cells. Mutation and/or overexpression of certain oncogenes is frequently associated with human cancer. To acquire transforming potential, the precursor of the Ras oncoprotein must undergo famesylation of the cysteine residue located in a carboxyi-terminal tetrapeptide. Inhibitors of the enzyme that catalyzes this modification, farnesyl protein transferase, have therefore been suggested as agents to combat tumors in which Ras contributes to transformation. Mutated, oncogenic forms of Ras are frequently found in many human cancers, most notably in more than 50% of colon and pancreatic carcinomas (Kohl et a , Science. Vol. 260. 1834 to 1837, 1993, incorporated herein in its entirety by reference). The compound of the present invention exhibits activity as an inhibitor of the enzyme farnesyl protein transferase and therefore is believed to be useful as an anti-cancer and anti-tumor agent. Further, the compound of the present invention may be active against any tumors that proliferate by virtue of farnesyl protein transferase. The racemate 6-[amino-(6-chloro-pyridin-3-yl)-(3-methyl-3H-imidazol-4-yl)-methyl]-4- (3-chloro-phenyl)-1-cyciopropylmethyl-1H-quinolin-2-one and other compounds that can inhibit farnesyl protein transferase are disclosed in United States Patent Application No. 09/501,163, filed February 9, 2000, and in International Publication No. WO 00/47574, both of which are hereby incorporated by reference in their entireties.

Example 12 and Example 13 Example 2 The above Schemes 1 through 4 illustrate non-limiting examples of the claimed methods of the invention. Referring to Scheme 1 , compounds of formula 2, exemplified by Example 1 in the Scheme, can be prepared from corresponding 2-alkoxy quinoline compounds by addition of thionyl chloride under an atmosphere of N 2 . Compounds of formula 2 can also be prepared as described in U.S. Patent Application No. 09/501,163, filed February 9, 2000 and published as WO 00/47574, both of which are hereby incorporated in their entireties by reference. The compound of formula 2 is condensed with a benzaldehyde compound of formula 3, such as p-anisaldehyde, to form a racemate of formula 1. The condensation can be in acidic conditions, such as in acetic acid, at ambient temperature. This racemate of formula 1 can optionally be derivatized to form other racemates of formula 1, such as the title compound of Example 2, prior to chiral molecule separation (Scheme 3). As an alternative to chiral molecule separation of the benzylidine molecule of formula 1 , a compound of formula 2 wherein R 8 comprises a benzylamino group can be separated on a chiral column (see Scheme 2), for subsequent formation of a compound of formula 2 wherein R 8 is -NH 2 , -NH(C 1 -C 10 alkyl), or -N(C C 10 alkyl)(C Cι 0 alkyl) (as in Scheme 3). Referring to Scheme 2, the benzylamino compound of formula 2 can be prepared from the corresponding benzylidine compound, exemplified by Example 2 in Scheme 2, by addition of sodium borohydride to the benzylamino compound in methanol. Alternatively, the benzylamino compound of formula 2 can be prepared by treating the (6-hydroxymethyl)2- alkoxy quinoline compound with thionyl chloride under an atmosphere of dry nitrogen to form the quinolinone, followed by condensation with a benzylamino compound optionally substituted on the phenyl group, such as p-methoxybenzylamine. This condensation can occur at a temperature of about -78°C, under an atmosphere of dry nitrogen. Referring to Scheme 3, either the benzylamino compound of formula 2, or the benzylidine of formula 1, can be applied to a chiral molecule separation column. The resulting (+) and/or (-) enantiomer of either the benzylamino compound of the benzylidine compound can be converted to an enantiomer of a compound of formula 2 wherein R 8 is - NH 2 , -NH(CrC 10 alkyl), or -N^ C™ alkyl)(C Cι 0 alkyl). The benzylidine moiety is converted to an amino group under acidic conditions, for example by addition of hydrochloric acid. The benzylamino group is converted to an amino group also under acidic conditions, for example by addition of TFA.

Oral administration is preferred. In general, the compound, and its pharmaceutically acceptable salts and solvates, and its prodrugs, are most desirably administered in dosages ranging from about 1.0 mg up to about 500 mg per day, preferably from about 1 to about 100 mg per day in single or divided (i.e., multiple) doses. The compound, or its salt or solvate, or a prodrug thereof, will ordinarily be administered in daily dosages ranging from about 0.01 to about 10 mg per kg body weight per day, in single or divided doses. Variations may occur depending on the weight and condition of the person being treated and the particular route of administration chosen. In some instances, dosage levels below the lower limit of the aforesaid range may be more than adequate, while in other cases still larger doses may be employed without causing any harmful side effect, provided that such larger doses are first divided into several small doses for administration throughout the day. For the combination therapies and pharmaceutical compositions described herein, the effective amounts of the compound of the invention and of the chemotherapeutic or other agent useful for inhibiting abnormal cell growth (e.g., other antiproliferative agent, anti- angiogenic, signal transduction inhibitor or immune-system enhancer) can be determined by those of ordinary skill in the art, based on the effective amounts for the compound described herein and those known or described for the chemotherapeutic or other agent. The formulations and routes of administration for such therapies and compositions can be based on the information described herein for compositions and therapies comprising the compound of the invention as the sole active agent and on information provided for the chemotherapeutic or other agent in combination therewith. The compound of the invention, or its salt or solvate or prodrug, may be administered alone or in combination with pharmaceutically acceptable carriers or diluents by any of the routes previously indicated, and such administration may be carried out in single or multiple doses. More particularly, the compound of this invention or its salt or solvate or prodrug can be administered in a wide variety of different dosage forms, i.e., combined with various pharmaceutically acceptable inert carriers in the form of tablets, capsules, lozenges, troches, hard candies, powders, sprays, creams, salves, suppositories, jellies, gels, pastes, lotions, ointments, elixirs, syrups, and the like. Such carriers include solid diluents or fillers, sterile aqueous media and various non-toxic organic solvents, etc. Moreover, oral pharmaceutical compositions can be suitably sweetened and/or flavored. For oral administration, tablets containing various excipients such as microcrystalline cellulose, sodium citrate, calcium carbonate, dicalcium phosphate and glycine may be employed along with various disintegrants such as starch (and preferably corn, potato or tapioca starch), alginic acid and certain complex silicates, together with granulation binders like polyvinylpyrrolidone, sucrose, gelatin and acacia. Additionally, lubricating agents such as magnesium stearate, sodium lauryl sulfate and talc are often very useful for tabletting purposes. Solid compositions of a similar type may also be employed as fillers in gelatin capsules; preferred materials in this connection also include lactose or milk sugar as well as high molecular weight polyethylene glycols. When aqueous suspensions and/or elixirs are desired for oral administration, the active ingredient may be combined with various sweetening or flavoring agents, coloring matter or dyes, and, if so desired, emulsifying and/or suspending agents as well, together with such diluents as water, ethanol, propylene glycol, glycerin and various like combinations thereof. For parenteral administration, solutions of the compound of the invention, or salt thereof, in either sesame or peanut oil or in aqueous propylene glycol may be employed. The aqueous solutions should be suitably buffered if necessary and the liquid diluent first rendered isotonic. These aqueous solutions are suitable for intravenous injection purposes. The oily solutions are suitable for intra-articular, intra-muscular and subcutaneous injection purposes. The preparation of all these solutions under sterile conditions is readily accomplished by standard pharmaceutical techniques well-known to those skilled in the art. Additionally, it is also possible to administer the compound, salt, or solvate topically and this may preferably be done by way of creams, jellies, gels, pastes, ointments and the like, in accordance with standard pharmaceutical practice. The compound of the invention may also be administered to a mammal other than a human. The dosage to be administered to a mammal will depend on the animal species and the disease or disorder being treated. The compound may be administered to animals in the form of a capsule, bolus, tablet or liquid drench. The compound may also be administered to animals by injection or as an implant. Such formulations are prepared in a conventional manner in accordance with standard veterinary practice. As an alternative, the compound may be administered with the animal feedstuff, and for this purpose a concentrated feed additive or premix may be prepared for mixing with the normal animal feed. The compounds of formula 1 and formula 2, including the compound of the invention (+)-6-[amino-(6-chloro-pyridin-3-yl)-(3-methyl-3H-imidazol-4-yl)-methyl]-4-(3-chloro-phenyl)-1- cyclopropylmethyl-1H-quinolin-2-one, exhibit activity as Ras famesylation inhibitors and are useful in the treatment of cancer and the inhibition of abnormal cell growth in mammals, including humans. The activity of the compounds of formula 1 and formula 2 as Ras famesylation inhibitors may be determined by their ability, relative to a control, to inhibit Ras farnesyl transferase in vitro. An example of one such procedure is described below. A crude preparation of human farnesyl transferase (FTase) comprising the cytosolic fraction of homogenized brain tissue is used for screening compounds in a 96-well assay format. The cytosolic fraction is prepared by homogenizing approximately 40 grams of fresh tissue in 100 ml of sucrose/MgCI 2 /EDTA buffer (using a Dounce homogenizer; 10-15 strokes), centrifuging the homogenates at 1000 g for 10 minutes at 4°C, re-centrifuging the supernatant at 17,000 g for 15 minutes at 4°C, and then collecting the resulting supernatant. This supernatant is diluted to contain a final concentration of 50 mM Tris HCI (pH 7.5), 5 mM DTT, 0.2 M KCI, 20 μM ZnCI 2 , 1 mM PMSF and re-centrifuged at 178,000 g for 90 minutes at 4°C. The supernatant, termed "crude FTase" is assayed for protein concentration, aliquoted, and stored at -70°C. The assay used to measure in vitro inhibition of human FTase is a modification of the method described by Amersham LifeScience for using their Farnesyl transferase (3H) Scintillation Proximity Assay (SPA) kit (TRKQ 7010). FTase enzyme activity is determined in a volume of 100 μl containing 50 mM N-(2-hydroxy ethyl) piperazine-N-(2-ethane sulfonic acid) (HEPES), pH 7.5, 30 mM MgCI 2 , 20 mM KCI, 25 mM Na 2 HP0 4 , 5 mM dithiothreitol (DTT), 0.01% Triton X-100, 5% dimethyl sulfoxide (DMSO), 20 mg of crude FTase, 0.12 mM [3H]- famesyl pyrophosphate ([3HJ-FPP; 36000 dpm/pmole, Amersham LifeScience), and 0.2 μM of biotinylated Ras peptide KTKCVIS (Bt-KTKCVIS) that is N-terminally biotinylated at its alpha amino group and was synthesized and purified by HPLC in house. The reaction is initiated by addition of the enzyme and terminated by addition of EDTA (supplied as the STOP reagent in kit TRKQ 7010) following a 45 minute incubation at 37°C. Prenylated and unprenylated Bt- KTKCVIS is captured by adding 150 μl of streptavidin-coated SPA beads (TRKQ 7010) per well and incubating the reaction mixture for 30 minutes at room temperature. The amount of radioactivity bound to the SPA beads is determined using a MicroBeta 1450 plate counter. Under these assay conditions, the enzyme activity is linear with respect to the concentrations of the prenyl group acceptor, Bt-KTKCVIS, and crude FTase, and inhibition of Bt-KTKCVIS interaction with FTase can be detected. The enzyme activity is saturating with respect to the prenyl donor, FPP. The assay reaction time is also in the linear range. The test compounds are routinely dissolved in 100% DMSO. Inhibition of farnesyl transferase activity is determined by calculating percent incorporation of tritiated-famesyl in the presence of the test compound versus its incorporation in control wells (absence of inhibitor). IC 50 values, that is, the concentration required to produce half maximal famesylation of Bt- KTKCVIS, is determined from the dose-responses obtained. The compound (+)-6-[amino-(6-chloro-pyridin-3-yl)-(3-methyl-3H-imidazol-4-yl)- methyl]-4-(3-chloro-phenyl)-1 -cyclopropylmethyl-1 H-quinolin-2-one was found to have an IC 50 value for inhibiting famesylation of the biotinylated KTKCVIS-peptide of less than 500 nM using the above-described assay.
