[0004] This invention provides compounds useful for the inhibition of farnesyl protein transferase (FPT). The compounds of this invention are represented by the formula:

[0005] or a pharmaceutically acceptable salt or solvate thereof, wherein:

[0006] one of a, b, c and d represents N or N+O−, and the remaining a, b, c, and d groups represent carbon, wherein each carbon has an R1 or R2 group bound to said carbon; or each of a, b, c, and d is carbon, wherein each carbon has an R1 or R2 group bound to said carbon;

[0009] When the optional bond is present between carbon atom 5 (i.e., C-5) and carbon atom 6 (i.e., C-6) (i.e., there is a double bond between C-5 and C-6) then there is only one A substituent bound to C-5 and there is only one B substituent bound to C-6 and A or B is other than H;

[0010] When the optional bond is not present between carbon atom 5 and carbon atom 6 (i.e., there is a single bond between C-5 and C-6) then there are two A substituents bound to C-5, wherein each A substituent is independently selected and two B substituents bound to C-6, wherein each B substituent is independently selected, i.e.,

[0185] The compounds of this invention: (i) potently inhibit farnesyl protein transferase, but not geranylgeranyl protein transferase I, in vitro; (ii) block the phenotypic change induced by a form of transforming Ras which is a farnesyl acceptor but not by a form of transforming Ras engineered to be a geranylgeranyl acceptor; (iii) block intracellular processing of Ras which is a farnesyl acceptor but not of Ras engineered to be a geranylgeranyl acceptor; and (iv) block abnormal cell growth in culture induced by transforming Ras.

[0186] The compounds of this invention inhibit farnesyl protein transferase and the farnesylation of the oncogene protein Ras. Thus, this invention further provides a method of inhibiting farnesyl protein transferase, (e.g., ras farnesyl protein transferase) in mammals, especially humans, by the administration of an effective amount (e.g. a therapeutically effective amount) of the tricyclic compounds described above. The administration of the compounds of this invention to patients, to inhibit farnesyl protein transferase, is useful in the treatment of the cancers described below.

[0187] This invention provides a method for inhibiting or treating the abnormal growth of cells, including transformed cells, by administering an effective amount (e.g. a therapeutically effective amount) of a compound of this invention. Abnormal growth of cells refers to cell growth independent of normal regulatory mechanisms (e.g., loss of contact inhibition). This includes the abnormal growth of: (1) tumor cells (tumors) expressing an activated Ras oncogene; (2) tumor cells in which the Ras protein is activated as a result of oncogenic mutation in another gene; and (3) benign and malignant cells of other proliferative diseases in which aberrant Ras activation occurs.

[0188] This invention also provides a method for inhibiting or treating tumor growth by administering an effective amount (e.g., a therapeutically effective amount) of the tricyclic compounds, described herein, to a mammal (e.g., a human) in need of such treatment. In particular, this invention provides a method for inhibiting or treating the growth of tumors expressing an activated Ras oncogene by the administration of an effective amount (e.g. a therapeutically effective amount) of the above described compounds.

[0189] The present invention also provides a method of treating proliferative diseases, especially cancers (tumors), comprising administering an effective amount (e.g., a therapeutically effective amount) of a compound of the invention, described herein, to a mammal (e.g., a human) in need of such treatment in combination with (2) an effective amount of at least one anti-cancer agent i.e. a chemotherapeutic agent and/or radiation).

[0190] The present invention also provides a method of treating proliferative diseases, especially cancers (tumors), comprising administering an effective amount (e.g., a therapeutically effective amount) of a compound of the invention, described herein, to a mammal (e.g., a human) in need of such treatment in combination with (2) an effective amount of at least one signal transduction inhibitor.

[0191] Examples of proliferative diseases (tumors) which may be inhibited or treated include, but are not limited to, lung cancer (e.g., lung adenocarcinoma), pancreatic cancers (e.g., pancreatic carcinoma such as, for example, exocrine pancreatic carcinoma), colon cancers (e.g., colorectal carcinomas, such as, for example, colon adenocarcinoma and colon adenoma), myeloid leukemias (for example, acute myelogenous leukemia (AML)), thyroid follicular cancer, myelodysplastic syndrome (MDS), bladder carcinoma, epidermal carcinoma, melanoma, breast cancer and prostate cancer.

[0192] It is believed that this invention also provides a method for inhibiting or treating 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 or treatment being accomplished by the administration of an effective amount (e.g. a therapeutically effective amount) of the tricyclic compounds described herein, to a mammal (e.g., a human) in need of such treatment. For example, the benign proliferative disorder neurofibromatosis, or tumors in which Ras is activated due to mutation or overexpression of tyrosine kinase oncogenes (e.g., neu, src, abl, Ick, and fyn), may be inhibited or treated by the tricyclic compounds described herein.

[0193] The tricyclic compounds useful in the methods of this invention inhibit or treat the abnormal growth of cells. Without wishing to be bound by theory, it is believed that these compounds may function through the inhibition of G-protein function, such as Ras p21, by blocking G-protein isoprenylation, thus making them useful in the treatment of proliferative diseases such as tumor growth and cancer. Without wishing to be bound by theory, it is believed that these compounds inhibit ras farnesyl protein transferase, and thus show antiproliferative activity against ras transformed cells.

[0508] Lines drawn into the ring systems indicate that the indicated bond may be attached to any of the substitutable ring carbon atoms.

[0509] Certain compounds of the invention may exist in different isomeric (e.g., enantiomers, diastereoisomers, atropisomers) forms. The invention contemplates all such isomers both in pure form and in admixture, including racemic mixtures. Enol forms are also included.

[0510] Certain tricyclic compounds will be acidic in nature, e.g. those compounds which possess a carboxyl or phenolic hydroxyl group. These compounds may form pharmaceutically acceptable salts. Examples of such salts may include sodium, potassium, calcium, aluminum, gold and silver salts. Also contemplated are salts formed with pharmaceutically acceptable amines such as ammonia, alkyl amines, hydroxyalkylamines, N-methylglucamine and the like.

[0511] Certain basic tricyclic compounds also form pharmaceutically acceptable salts, e.g., acid addition salts. For example, the pyrido-nitrogen atoms may form salts with strong acid, while compounds having basic substituents such as amino groups also form salts with weaker acids. Examples of suitable acids for salt formation are hydrochloric, sulfuric, phosphoric, acetic, citric, oxalic, malonic, salicylic, malic, fumaric, succinic, ascorbic, maleic, methanesulfonic and other mineral and carboxylic acids well known to those in the art. The salts are prepared by contacting the free base form with a sufficient amount of the desired acid to produce a salt in the conventional manner. The free base forms may be regenerated by treating the salt with a suitable dilute aqueous base solution such as dilute aqueous NaOH, potassium carbonate, ammonia and sodium bicarbonate. The free base forms differ from their respective salt forms somewhat in certain physical properties, such as solubility in polar solvents, but the acid and base salts are otherwise equivalent to their respective free base forms for purposes of the invention.

[0512] All such acid and base salts are intended to be pharmaceutically acceptable salts within the scope of the invention and all acid and base salts are considered equivalent to the free forms of the corresponding compounds for purposes of the invention.

[0513] The compounds of formula 1.0 can exist in unsolvated as well as solvated forms, including hydrated forms, e.g., hemi-hydrate. In general, the solvated forms, with pharmaceutically acceptable solvents such as water, ethanol and the like are equivalent to the unsolvated forms for purposes of the invention.

[0514] The method of treating proliferative diseases (cancer), according to this invention, includes a method for treating (inhibiting) the abnormal growth of cells, including transformed cells, in a patient in need of such treatment (e.g., a mammal such as a human), by administering, concurrently or sequentially, an effective amount of a compound of this invention and an effective amount of a chemotherapeutic agent and/or radiation. Abnormal growth of cells means cell growth independent of normal regulatory mechanisms (e.g., loss of contact inhibition), including the abnormal growth of: (1) tumor cells (tumors) expressing an activated ras oncogene; (2) tumor cells in which the ras protein is activated as a result of oncogenic mutation in another gene; and (3) benign and malignant cells of other proliferative diseases.

[0515] In preferred embodiments, the methods of the present invention include methods for treating or inhibiting tumor growth in a patient in need of such treatment (e.g., a mammal such as a human) by administering, concurrently or sequentially, (1) an effective amount of a compound of this invention and (2) an effective amount of at least one antineoplastic agent, microtubule affecting agent and/or radiation therapy. Examples of tumors which may be treated include, but are not limited to, epithelial cancers, e.g., prostate cancer, lung cancer (e.g., lung adenocarcinoma), pancreatic cancers (e.g., pancreatic carcinoma such as, for example, exocrine pancreatic carcinoma), breast cancers, colon cancers (e.g., colorectal carcinomas, such as, for example, colon adenocarcinoma and colon adenoma), ovarian cancer, and bladder carcinoma. Other cancers that can be treated include melanoma, myeloid leukemias (for example, acute myelogenous leukemia), sarcomas, thyroid follicular cancer, and myelodysplastic syndrome. In particular, the proliferative disease (tumor) that may be treated is selected from lung cancer, pancreatic cancer, prostate cancer and myeloid leukemia. Preferrably for the methods of the present invention, the disease (tumor) that may be treated is selected from lung cancer and myeloid leukemia.

[0516] The methods of treating proliferative diseases, according to this invention, also include a method for treating (inhibiting) 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. This method comprises administering, concurrently or sequentially, an effective amount of a compound of this invention and an effective amount of an antineoplastic agent and/or radiation therapy to a patient in need of such treatment (e.g., a mammal such as a human). Examples of such proliferative diseases which may be treated include: the benign proliferative disorder neurofibromatosis, or tumors in which ras is activated due to mutation or overexpression of tyrosine kinase oncogenes (e.g., neu, src, abl, Ick, lyn, fyn).

[0517] For radiation therapy, y-radiation is preferred.

[0518] The methods of treating proliferative diseases (cancer), according to this invention, also include a method for treating (inhibiting) the abnormal growth of cells, including transformed cells, in a patient in need of such treatment (e.g., a mammal such as a human), by administering, concurrently or sequentially, an effective amount of a compound of this invention and an effective amount of at least one signal transduction inhibitor.

[0519] Typical signal transduction inhibitors include but are not limited to:

[0520] (i) Bcr/abl kinase inhibitors such as, for example, STI 571 (Gleevec);

[0521] (ii) Epidermal growth factor (EGF) receptor inhibitor such as, for example, Kinase inhibitors (Iressa, SSI-774) and antibodies (Imclone: C225 [Goldstein et al. (1995), Clin Cancer Res. 1:1311-1318], and Abgenix: ABX-EGF) and

[0522] (iii) Her-2/neu receptor inhibitors such as, for example, Herceptin® (trastuzumab).

[0523] As used herein the following terms have the following meanings unless indicated otherwise:

[0524] antineoplastic agent—a chemotherapeutic agent effective against cancer;

[0525] concurrently—(1) simultaneously in time, or (2) at different times during the course of a common treatment schedule; and

[0526] sequentially—(1) administration of one component of the method ((a) compound of the invention, or (b) chemotherapeutic agent, signal transduction inhibitor and/or radiation therapy) followed by administration of the other component or components; after adminsitration of one component, the next component can be administered substantially immediately after the first component, or the next component can be administered after an effective time period after the first component; the effective time period is the amount of time given for realization of maximum benefit from the administration of the first component.

[0527] The term “in association with” as used herein in reference to the combination therapies of the invention means-the agents or components are adminstered concurrently or sequentially as defined above.

CHEMOTHERAPEUTIC AGENTS

[0528] Classes of compounds that can be used as chemotherapeutic agents (antineoplastic agent/microtubule affecting agents) include but are not limited to: alkylating agents, antimetabolites, natural products and their derivatives, hormones and steroids (including synthetic analogs), and synthetics.

[0535] Methods for the safe and effective administration of most of these chemotherapeutic agents are known to those skilled in the art. In addition, their administration is described in the standard literature. For example, the administration of many of the chemotherapeutic agents is described in the “Physicians' Desk Reference” (PDR), e.g., 1996 edition (Medical Economics Company, Montvale, N.J. 07645-1742, USA); the disclosure of which is incorporated herein by reference thereto.

MICROTUBULE AFFECTING AGENTS

[0536] As explained above, the present invention also provides methods of treating diseased cells by contacting the cells with an FPT inhibiting compound of the invention and a microtubule affecting agent (e.g., paclitaxel, a paclitaxel derivative or a paclitaxel-like compound). As used herein, a microtubule affecting agent is a compound that interferes with cellular mitosis, i.e., having an anti-mitotic effect, by affecting microtubule formation and/or action. Such agents can be, for instance, microtubule stabilizing agents or agents which disrupt microtubule formation.

[0537] Microtubule affecting agents useful in the invention are well known to those of skill in the art and include, but are not limited to allocolchicine (NSC 406042), Halichondrin B (NSC 609395), colchicine (NSC 757), colchicine derivatives (e.g., NSC 33410), dolastatin 10 (NSC 376128), maytansine (NSC 153858), rhizoxin (NSC 332598), paclitaxel (Taxol®, NSC 125973), paclitaxel derivatives (e.g., Taxotere, NSC 608832), thiocolchicine (NSC 361792), trityl cysteine (NSC 83265), vinblastine sulfate (NSC 49842), vincristine sulfate (NSC 67574), epothilone A, epothilone, and discodermolide (see Service, (1996) Science, 274:2009) estramustine, nocodazole, MAP4, and the like. Examples of such agents are also described in the scientific and patent literature, see, e.g., Bulinski (1997) J. Cell Sci. 110:3055-3064; Panda (1997) Proc. Natl. Acad. Sci. USA 94:10560-10564; Muhlradt (1997) Cancer Res. 57:3344-3346; Nicolaou (1997) Nature 387:268-272; Vasquez (1997) Mol. Biol. Cell. 8:973-985; Panda (1996) J. Biol. Chem. 271:29807-29812.

[0538] Particularly preferred agents are compounds with paclitaxel-like activity. These include, but are not limited to paclitaxel and paclitaxel derivatives (paclitaxel-like compounds) and analogues. Paclitaxel and its derivatives (e.g. Taxol and Taxotere) are available commercially. In addition, methods of making paclitaxel and paclitaxel derivatives and analogues are well known to those of skill in the art (see, e.g., U.S. Pat. Nos. 5,569,729; 5,565,478; 5,530,020; 5,527,924; 5,508,447; 5,489,589; 5,488,116; 5,484,809; 5,478,854; 5,478,736; 5,475,120; 5,468,769; 5,461,169; 5,440,057; 5,422,364; 5,411,984; 5,405,972; and 5,296,506).

[0539] More specifically, the term “paclitaxel” as used herein refers to the drug commercially available as Taxol® (NSC number: 125973). Taxol® inhibits eukaryotic cell replication by enhancing polymerization of tubulin moieties into stabilized microtubule bundles that are unable to reorganize into the proper structures for mitosis. Of the many available chemotherapeutic drugs, paclitaxel has generated interest because of its efficacy in clinical trials against drug-refractory tumors, including ovarian and mammary gland tumors (Hawkins (1992) Oncology, 6: 17-23, Horwitz (1992) Trends Pharmacol. Sci. 13: 134-146, Rowinsky (1990) J. Natl. Canc. Inst. 82: 1247-1259).

[0540] Additional microtubule affecting agents can be assessed using one of many such assays known in the art, e.g., a semiautomated assay which measures the tubulin-polymerizing activity of paclitaxel analogs in combination with a cellular assay to measure the potential of these compounds to block cells in mitosis (see Lopes (1997) Cancer Chemother. Pharmacol. 41:37-47).

[0541] Generally, activity of a test compound is determined by contacting a cell with that compound and determining whether or not the cell cycle is disrupted, in particular, through the inhibition of a mitotic event. Such inhibition may be mediated by disruption of the mitotic apparatus, e.g., disruption of normal spindle formation. Cells in which mitosis is interrupted may be characterized by altered morphology (e.g., microtubule compaction, increased chromosome number, etc.).

[0542] In a preferred embodiment, compounds with possible tubulin polymerization activity are screened in vitro. In a preferred embodiment, the compounds are screened against cultured WR21 cells (derived from line 69-2 wap-ras mice) for inhibition of proliferation and/or for altered cellular morphology, in particular for microtubule compaction. In vivo screening of positive-testing compounds can then be performed using nude mice bearing the WR21 tumor cells. Detailed protocols for this screening method are described by Porter (1995) Lab. Anim. Sci., 45(2):145-150.

[0543] Other methods of screening compounds for desired activity are well known to those of skill in the art. Typically such assays involve assays for inhibition of microtubule assembly and/or disassembly. Assays for microtubule assembly are described, for example, by Gaskin et al. (1974) J. Molec. Biol., 89: 737-758. U.S. Patent No. 5,569,720 also provides in vitro and in vivo assays for compounds with paclitaxel-like activity.

[0544] Methods for the safe and effective administration of the above-mentioned microtubule affecting agents are known to those skilled in the art. In addition, their administration is described in the standard literature. For example, the administration of many of the chemotherapeutic agents is described in the “Physicians' Desk Reference” (PDR), e.g., 1996 edition (Medical Economics Company, Montvale, NJ 07645-1742, USA); the disclosure of which is incorporated herein by reference thereto.

[0545] General Preparative Schemes

[0546] The following processes may be employed to produce compounds of the invention.

Pyridyl Tricyclic Compounds

[0547] One skilled in the art will appreciate that the compounds of the invention represented by Formula 1, wherein one of a, b, c or d is N or N+—O− can be prepared according to the following schemes:

[0548] The synthesis of 5-bromo tricyclic compound 1b begins with bridgehead olefin 1a (J. Med Chem (1998), 41,1561-1567) which is treated with dibromo dimethylhydantoin in triflic acid media. Further treatment of the vinylbromide with potassium t-butoxide in the presence of the appropriate secondary amine gives the 5 and 6-substituted enamine adducts. When Y is NH (piperazine case), acylations, sulfonylations and amide formation can be carried out using standard procedures. Treatment of these amine adducts with HCl(aq) at the appropriate temperatures results in the formation of the 5 and 6 azaketones, 1f and 1e respectively.

[0549] In cases where secondary enamines were required, synthesis from 1f and 1e-azaketones were utilized as outlined in scheme 2. Thus, the appropriate ketone and 5 amine was refluxed in toluene in the presence of p-toluene sulfonic acid in a Dean Stark apparatus.

[0550] Synthesis of 3-carbon spaced analogs can be prepared as outlined in scheme 3. Thus, subjecting tricyclic vinyl bromide 1 b to a Heck type reaction using ethyl acrylate and catalyzed by Pd0 gives the α-β un-saturated ester 3a. Reduction of the conjugated double bond was carried out using copper chloride-sodium borohydride reducing reagent. The ester was further reduced to alcohol using lithium aluminum hydride. Treatment of the alcohol with methanesulfonyl chloride in an appropriate aprotic solvent, followed by displacement with an appropriate sodium salt resulted in the desired imidazole targets. In most cases, separation of isomers were effected at this point. Where the R group of 3e was a BOC group, deprotection using HCl-dioxane gave the hydrochloride salts of amines. Using standard chemistry, these amines were converted to ureas, carbamates, sulfonamides and amides.

[0551] Preparation of 6-substituted 3-carbon spaced imidazole compounds was carried out as outlined in scheme 4. A mixture of ketones if and 1i were treated with N-phenytrifluoromethane sulfonimide to give a seperable mixture of 5 and 6-tricyclic triflate compounds. The 6-trilate adduct was converted to the desired 3-carbon spaced analogs using similar protocol as described for the 5-bromo tricyclic compounds outlined in scheme 3.

[0552] Two carbon spaced analogs were prepared as outlined in scheme 5. Thus, triflate 4b was subjected to Stille chemistry, by reacting with tributylvinyl stannate catalyzed by an appropriate Pd0 to afford the tricyclic vinyl compound 5b. The 2-carbon spaced compounds were obtained by treating the tricylic compound with the appropriate imidazole that had been previously treated with Buli-THF in a sealed tube and refluxed at 120° C. Further funtionalization was carried out as previously described. Suberane compounds were prepared in a similar way.

[0553] Scheme 6 illustrates method of making amine 6b through phthalimido displacement of a mesylate followed by hydazine hydrolysis of the phthalimido moiety. Amine 6b can be converted to targets that have acyl, sufonyl,

[0554] Lactams 7a can be prepared from amine 6b by reacting with bromo butanonyl acid chloride as outlined in scheme 7.

[0555] Cyclic urea can be prepared from the mesylate shown above by treating with the salt of the cyclic urea 8a as outlined in scheme 8.

[0556] Amides from 3-carbon spaced carboxylic acid 9a and 9c can be prepared as outlined in scheme 10 using either DEC—HOBT mediated protocol or from the appropriate acid chloride.

[0557] Preparation of piperazine compounds off the bridgehead starts from mesylate aa which is reacted with CBZ-protected piperazine. The BOC group is then removed and the resulting amine 10c is functionalized appropriately. Removal of CBZ group off the piperazine is effected with TMSI.

[0558] Compound 12a is reduced with DIBAL in an inert solvent such as toluene or tetrahydrofuran to give 12b after acidic workup. Treatment of 12b with an appropriately substituted and tritylated imidazole iodide in the presence of ethylmagnesium bromide in solvents such as dichloromethane at ambient temperature yields the adduct 12c. Elimination of the hydroxyl group by converting the hydroxyl group to an appropriate leaving group such as a mesylate, tosylate, or halide, using methanesulfonyl chloride, p-toluenesulfonyl chloride, or thionyl chloride, followed by elimination using an appropriate base such as triethylamine gives 12e. Removal of the trityl group with acid such as trifluoroacetic acid or hydrochloric acid gives the double bond compound 12f which is then hydrogenated using an appropriate catalyst such as platinum oxide under from 1 to 55 psi of hydrogen in an appropriate solvent such as ethanol gave the desired product 12g.

[0559] Alternatively the ester 12a can be saponified with an appropriate base such as lithium hydroxide to obtain the acid 12h. Converting the acid 12h to the “Weinreb amide” followed by reaction with an appropriately substituted and tritylated imidazole iodide in the presence of ethylmagnesium bromide in solvents such as dichloromethane at ambient temperature yields the adduct 12c (shown in Scheme 12 below).

[0560] Compounds of type 12L were prepared as shown above. Oxidation of the hydroxyl compound 12c can be accomplished with the Dess Martin periodinane to obtain 12j. Reaction with a grignard reagent gave 12k. The trityl group is removed under standard conditions mentioned above to give the desired compound 12L.

[0561] Single methylene bridgehead C-Imidazole derivatives (13c) were prepared as shown above. Compound 13a was first converted to bromide 13b. Treatment of compound 13b with C-imidazole cuprates (prepared from corresponding iodo imidazole) yielded the adduct 13c.

[0562] Scheme 14: Preparation of one-methylene piperazines

[0563] Ketone A is brominated with brominating reagents such as NBS, with a small amount of an activator such as benzoyl peroxide, in solvents such as dichloromethane at elevated temperature, such as 80-100° C. to give dibromo compound B.

[0564] Dibromo compound B is reacted with a base such as DBU in a solvent such as dichloromethane at temperatures from 0° C. to room temperature to give vinylbromides C and D. These vinylbromides are separated by chromatography such as silica gel flash chromatography using solvents mixtures such as ethyl acetate and hexane. Alternatively, vinylbromides C and D can be separated by crystallization from solvents such as dichloromethane.

[0565] The ketone groups of separated vinylbromides C and D are reduced to the corresponding alcohols E and F with a reducing agent such as NaBH4 in solvents such as methanol or ethanol at temperatures of 0° C. to room temperature.

[0566] The resulting alcohols functions of E and F are converted to a leaving group, such as a halide, with reagents such as SOCl2 in solvents such as dichloromethane containing a base such as 2,6-lutidine and running the reaction at 0° C. to room temperature. The resulting intermediate halides are reacted, without purification, with piperazine or a protected piperazine, such as BOC-piperazine in a solvent such as dichloromethane at room temperature giving intermediates G and H.

[0567] The vinylhalide intermediates are carbonylated with CO gas under a pressure of about 100 psi and a temperature of 80° C. to 100° C. using a palladium catalyst such as PdCl2 and triphenyl phosphine in toluene and containing DBU and an alcohol such as methanol. If methanol is used, methyl esters I and J are obtained.

[0568] The ester functions are of I and J are reduced to hydroxymethyl functions of K and L. This can be done directly by first removing the protecting BOC group with TFA or HCl-dioxane and then reducing with a reducing agent such as DIBAL-H, followed by reintroduction of the BOC group with di-tert-butyl dicarbonate. Alternatively, the ester function is hydrolyzed with LiOH and water followed by neutralization with citric acid. The resulting carboxylic acids are then converted into a function that is easily reduced, such as a mixed anhydride or an acyl imidazole. This is done by reacting the resulting carbocylic acids with a chloroformate to form the mixed anhydride or with carbonydiimidazole to form the acyl imidazole (Synlett. (1995), 839). The resulting activated carboxylic acids are reduced with NaBH4 in solvents such as methanol, ethanol or aqueous THF.

[0569] The hydroxy functions of K and L are converted into leaving groups such as a methanesulfonate or an arylsulfonate such as a tosylate, by reacting with the appropriate sulfonyl chloride in dichloromethane containing a base such as triethylamine. The sulfonate leaving groups can be displaced by nucleophiles such amines. The nucloephile can also be basic heterocycles such as imidazole or a substituted imidazole. In the case of an imidazole, the anion of the imidazole is first formed with NaH in DMF and then reacted with the above sulfonate. Displacement of the sulfonates with a nucleophile gives O and P, which can be converted to the compounds of this invention 1.0, by first removing the BOC protecting group and then forming the desired amide, urea, carbamate or sulfonamide on the resulting amine by methods well known in the art.

[0570] The vinylhalide or vinyltriflate intermediates A and B, (described in other general schemes) are carbonylated with CO gas under a pressure of about 100 psi and a temperature of 80° C. to 100° C. using a palladium catalyst such as PdCl2 and triphenyl phosphine in toluene and containing DBU and an alcohol such as methanol. If methanol is used, methyl esters C and D are obtained. Intermediates C and D are reacted as are intermediates I and J in the general scheme for one methylene piperazines to yield compounds of Formula 1.0, of this invention.

[0571] Alternatively, Intermediates A and B can be reacted with tin vinylether E, in the presence of PdCl2, as described in Tetrahedron, (1991), 47, 1877, to yield vinylethers F and G (Scheme 15a). Allowing F and G to stand until aldehyde is visible by NMR (at least two weeks) and then reacting with Hg(OAc)2, Kl followed by NaBH4, as described in J. Chem. Soc., Perkin Trans., (1984), 1069 and Tet. Lett., (1988), 6331, yields mixtures H, I and J, K. Intermediates H and J are separated and reacted as are intermediates K and L in the general scheme for one methylene piperazines to yield compounds of Formula 1.0, of this invention.

[0572] Compounds with substitution along the chain can be synthesized starting with a substituted ethyl acrylate derivative. Addition of imidazole across the olefin followed by reduction gives the terminal alkene, which can be added to the appropriately substituted vinyl bromide under Heck reaction conditions. Selective reduction of the di-substituted olefin gives the saturated derivative (Scheme 16).

[0573] The synthesis of the C-linked imidazoles proceeds through the Heck reaction of the appropriately substituted vinyl imidazole with the appropriate vinyl bromide. Selective reduction of the resulting di-substituted olefin gives the target compound. A similar procedure can be carried out with differentially N-substituted imidazoles to give N-alkyl imidazole derivatives (Scheme 17).

Suberyl Compounds

[0574] One skilled in the art will appreciate that the compounds of the invention represented by Formula 1.0, wherein a, b, c or d is C can be prepared according to the following schemes:

[0575] Tricyclic vinyl bromide azaketone 4b was prepared as described by Rupard et. al. (J. Med. Chem. 1989, 32, 2261-2268). Reduction of ketone to alcohol 4c was carried out with NaBH4. The alcohol was converted to chloride 4d and then treated with N-methylpiperidine Grignard reagent to give piperidine derivative 4e. Demethylation was effected with ethyl chloroformate followed by acid hydrolysis and subsequent derivitization (i.e sulfonylation, acylation and carbomylation etc.). Preparation of compounds with 3-carbon substituted imidazole moieties on the suberane trycyclic bridgehead was carried out in a similar way as described in scheme 3.

PREPARATION OF INTERMEDIATES AND EXAMPLES

Preparative Example 1

[0576] Step A Preparation of Compound (2).

[0577] Loratadine® (448 g, 1.17 mol) was refuxed in 2 L of 70% aqueous HCl (1.4 L conc.HCl in 600 ml H2O) for 12h. The reaction mixture was then cooled and poured into ice. It was then basified with 950 mL of 50% NaOH followed by extraction with CH2Cl2 (1×4L, and 2×2.5L). The organic phase was washed with brine, dried over Na2SO4 and MgSO4 and then filtered. All the volatiles were then removed to give 368 g of the title compound (2). MH+=311

[0578] To the title compound from Preparative Example 1, Step A (363 g, 1.17 mol) was added trifuromethane sulfonic acid (1.8 Kg) under N2. The reaction mixture was refluxed at 170° C. The progress of the reaction was monitored by 1H NMR. After 4 days the reaction was only 63% complete. After 8 days the reaction was found to be 80% complete according to 1H NMR; thus another 130 mL of CF3SO3H were added and refuxing continued for another 24 h. It was then poured into ice and basified with 800 mL of NaOH (50%) and extracted twice with CH2Cl2(1×8L then 1×7L). The organic phase was combined, washed with H2O and filtered through celite. It was then dried over MgSO4 and Na2SO4 and again filtered through celite. The filtrate was concentrated to give a black brown semi-solid that was pre adsorbed on 600 g of silica gel and then chromatographed on 2.3 Kg of silica gel eluting first with 5% CH3OH—CH2Cl2 (saturated with ammonia) and then with 10% CH3OH—CH2Cl2 (saturated with ammonia) to give 102 g of the title compound (3) as a solid. mp=73-75; MS (FAB) m/z 483 (MH+).

[0579] To a solution of the title compound of Preparative Example 1, Step B (145 g) in 1 L of CH2Cl2 at 0° C. was added ethylchloroformate (55 mL), dropwise. The reaction mixture was stirred at room temperature overnight. It was further diluted with 1 L CH2Cl2 and stirred with 2L of dilute NaHCO3, pH ˜7-8. The organic layer was separated and dried over MgSO4 and Na2SO4, filtered and concentrated to afford 174 g of a brown black gum. The crude compound was purified by silica gel column chromatography, eluting with 20-60% ethyl acetate-hexane to afford the title compound (4). MS (FAB) m/z 383 (MH+).

[0580] The title compound of Preparative Example 1, Step C (251 g, 0.65 mol) was dissolved in 1.65 L of CH2Cl2 and dibromo dimethylhydantoin, (132 g, 0.462 mol) was then added. The solution was stirred until the system was homogeneous. The solution was cooled to 0° C. under N2 atmosphere and 174 mL of CF3SO3H were added over 37 min. while keeping temperatures between −1 to 1° C. The reaction mixture was stirred for 3 h, cooled to −10° C. and basified with 50% NaOH (170 mL), keeping the temperature below 1° C. The aqueous phase was extracted with CH2Cl2 and then dried over MgSO4, dried and concentrated to give 354 g of yellow foam that was chromatographed on silica gel eluting with 10-50% of ethyl acetate-hexanes gradient to give 50 g of compound (5) (14% yield) and 147 grams of the desired title compound (6) (49% yield). Compound (6) MS m/z (rel intens) 462 (MH+); Compound (5) MS m/z (rel intens) 542 (MH+).

[0581] To a solution of piperazine 0.186 g (2.2 mmol, 5 equiv.) in 5 mL of THF was added 0.20 g (0.4 mmol) of compound 6 (from Preparative Example 1, Step D. The reactants stirred at room temperature until everything was in solution. To this mixture was added potassium t-butoxide (0.243 g, 2.1 mmol, 5 equivalents) in one portion. The reaction mixture was stirred at room temperature for 2 h.

433

[0989] A library of compounds was prepared by solution phase parallel synthesis. A generic structure of these compounds is shown in FIG. 1 above. The R1 group on the imidazole ring can be H or CH3, the R2 on N-1 of the piperidine is varied in the library.

[0990] Library compounds were prepared using compound (29) from Preparative Example 4 or Compounds (51a) or (52a) from Preparative Example 49 above as templates as shown in Scheme A. Synthesis is initiated in test tubes by reacting compound (29), (51a) or (52a) with multiple equivalents of a variety of isocyanates, amines, acids, acid chlorides, sulfonyl chlorides and chloroformates in dichloromethane or chloroform. When urea is the desired product, the reaction can be carried out using isocyanates directly, or alternatively, treating an amine with CDI for several hours, then subject the templates to this solution overnight. When acids are used, the reaction is carried out in the presence of a coupling reagent such as PyBrop and a base such as DIEA overnight. When acid chlorides, sulfonyl chlorides or chloroformates are used, the reaction is typically conducted in the presence of triethylamine. After reaction, an excess amount of polystyrene aminomethyl resin is added to the reaction test tubes, and the reaction allowed to stand overnight. At which time each test tube is filtered through a Bio-Rad Poly-Prep chromatography column into another test tube, and the resin is washed with dichloromethane and MeOH. The combined filtrate solution is concentrated by rotovap evaporation. The residue in each test tube is then dissolved in H2O /CH3CN (50/50, containing 1% TFA) and purified by Gilson 215 liquid Handling-HPLC system to give pure product. The product was identified by mass spectroscopy. Library compounds prepared in this fashion are shown in Table 1 and Table 2.

Also, in accordance with the knowledge of the skilled clinician, the therapeutic protocols (e.g., dosage amounts and times of administration) can be varied in view of the observed effects of the administered signal transduction inhibitors on the patient, and in view of the observed responses of the disease to the administered therapeutic agents.

[1263] In another example of combination therapy, the compound of Formula (I) is administered orally in a range of from 50 to 400 mg/day, in two divided doses in association with the signal tranduction inhibitor, EGF receptor kinase inhibitor, Iressa (ZD1839), which is administered orally in the range of 150-700 mg/day.

[1265] In the methods of the present invention, an FPT inhibitor compound of formula (I) is administered concurrently or sequentially with another therapeutic agent (i.e. a chemotherapeutic agent, a signal transduction inhibitor and/or radiation). Thus, it is not necessary that, for example, the therapeutic agent and the FPT inhibitor compound of formula (I) be administered simultaneously, just prior to or after one another.

[1266] Also, in general, the FPT inhibitor compound of formula (I), the chemotherapeutic agent, signal transduction inhibitor and/or radiation, do not have to be administered in the same pharmaceutical composition, and may, because of different physical and chemical characteristics, have to be administered by different routes. For example, the FPT inhibitor compound of formula (I) may be administered orally to generate and maintain good blood levels thereof, while the chemotherapeutic agent may be administered intravenously. The determination of the mode of administration and the advisability of administration, where possible, in the same pharmaceutical composition, is well within the knowledge of the skilled clinician. The initial administration can be made according to established protocols known in the art, and then, based upon the observed effects, the dosage, modes of administration and times of administration can be modified by the skilled clinician .

[1267] The particular choice of the FPT inhibitor compound of formula (1), the chemotherapeutic agent, signal transduction inhibitor and/or radiation will depend upon the diagnosis of the attending physicians and their judgement of the condition of the patient and the appropriate treatment protocol.

[1268] The FPT inhibitor compound of formula (1), chemotherapeutic agent, signal transduction inhibitor and/or radiation may be administered concurrently (e.g., simultaneously, just prior to or after, or within the same treatment protocol) or sequentially, depending upon the nature of the proliferative disease, the condition of the patient, and the actual choice of chemotherapeutic agent, signal transduction inhibitor and/or radiation to be administered in conjunction (i.e., within a single treatment protocol) with the FPT inhibitor compound of formula (1).

[1269] If the FPT inhibitor compound of formula (1), chemotherapeutic agent, signal transduction inhibitor and/or radiation are not administered simultaneously, then the initial order of administration of the FPT inhibitor compound of formula (1), chemotherapeutic agent, signal transduction inhibitor and/or radiation, may not be important. Thus, the FPT inhibitor compound of formula (I) may be administered first followed by the administration of the chemotherapeutic agent, signal transduction inhibitor and/or radiation; or the chemotherapeutic agent, signal transduction inhibitor and/or radiation may be administered first followed by the administration of the FPT inhibitor compound of formula (I). This alternate administration may be repeated during a single treatment protocol. The determination of the order of administration, and the number of repititions of administration of each therapeutic agent during a treatment protocol, is well within the knowledge of the skilled physician after evaluation of the disease being treated and the condition of the patient. For example, the chemotherapeutic agent, signal transduction inhibitor and/or radiation may be administered first, especially if it is a cytotoxic agent, and then the treatment continued with the administration of the FPT inhibitor compound of formula (1), followed by, where determined advantageous, the administration of the chemotherapeutic agent, signal transduction inhibitor and/or radiation, and so on until the treatment protocol is complete.

[1270] Thus, in accordance with experience and knowledge, the practising physician can modify each protocol for the administration of a component (therapeutic agent—i.e., FPT inhibitor compound of formula (I), chemotherapeutic agent, signal transduction inhibitor or radiation) of the treatment according to the individual patient's needs, as the treatment proceeds.

[1271] The attending clinician, in judging whether treatment is effective at the dosage administered, will consider the general well-being of the patient as well as more definite signs such as relief of disease-related symptoms, inhibition of tumor growth, actual shrinkage of the tumor, or inhibition of metastasis. Size of the tumor can be measured by standard methods such as radio-logical studies, e.g., CAT or MRI scan, and successive measure-ments can be used to judge whether or not growth of the tumor has been retarded or even reversed. Relief of disease-related symptoms such as pain, and improvement in overall condition can also be used to help judge effectiveness of treatment.

[1272] While the present invention has been described in conjunction with the specific embodiments set forth above, many alternatives, modifications and variations thereof will be apparent to those of ordinary skill in the art. All such alternatives, modifications and variations are intended to fall within the spirit and scope of the present invention.
