MICROTUBULE AFFECTING AGENTS 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 paclitaxel, a paclitaxel derivative or a paclitaxel-like compound). As used herein, a microtubule affecting agent is a compound that interferes with cellular mitosis, 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.

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 NSC 33410), dolastatin 10 (NSC 376128), maytansine (NSC 153858), rhizoxin (NSC 332598), paclitaxel (Taxolo, NSC 125973), paclitaxel derivatives 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, 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.

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 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, U.S.

Patent 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).

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).

Additional microtubule affecting agents can be assessed using one of many such assays known in the art, 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).

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, disruption of normal spindle formation. Cells in which mitosis is interrupted may be characterized by altered morphology microtubule compaction, increased chromosome number, etc.).

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.

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.

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), 1996 edition (Medical Economics Company, Montvale, NJ 07645-1742, USA); the disclosure of which is incorporated herein by reference thereto.

Thus, subjecting tricyclic vinyl bromide 1 b to a Heck type reaction using ethyl acrylate and catalyzed by Pd 0 gives the ac-P 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 HCIdioxane gave the hydrochloride salts of amines. Using standard chemistry, these amines were converted to ureas, carbamates, sulfonamides and amides.

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.

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).

Scheme 14: Preparation of one-methylene piperazines 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 80-1000 C to give dibromo compound B.

S"Br Br RRN R N A B 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.

The ketone groups of separated vinylbromides C and D are reduced to the corresponding alcohols E and F with a reducing agent such as NaBH 4 in solvents such as methanol or ethanol at temperatures of 0°C to room temperature.

The resulting alcohols functions of E and F are converted to a leaving group, such as a halide, with reagents such as SOCI2 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.

The vinylhalide intermediates are carbonylated with CO gas under a pressure Sof about 100 psi and a temperature of 80°C to 100°C using a palladium catalyst such as PdCI 2 and triphenyl phosphine in toluene and containing DBU and an alcohol such as methanol.

This can be done directly by first removing the protecting BOC group with TFA or HCI-dioxane and then reducing with a reducing agent such as DIBAL-H, followed by reintroduction of the BOC group with di-tert-butyl dicarbonate. Altematively, 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 NaBH 4 in solvents such as methanol, ethanol or aqueous THF.

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.

1 Figure 1 Figure 2 A library of compounds was prepared by solution phase parallel synthesis. A generic structure of these compounds is shown in Figure 1 above. The R 1 group on the imidazole ring can be H or CH 3 the R 2 on N-1 of the piperidine is varied in the library.

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 (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 H 2 0/CH 3 CN (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.

Thus, it is not necessary that, for example, the therapeutic agent and the FPT inhibitor compound of formula be administered simultaneously, just prior to or after one another.

Also, in general, the FPT inhibitor compound of formula 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 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.

The particular choice of the FPT inhibitor compound of formula 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.

The FPT inhibitor compound of formula chemotherapeutic agent, signal transduction inhibitor and/or radiation may be administered concurrently 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 within a single treatment protocol) with the FPT inhibitor compound of formula If the FPT inhibitor compound of formula 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 chemotherapeutic agent, signal transduction inhibitor and/or radiation, may not be important. Thus, the FPT inhibitor compound of formula 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 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 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.

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

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, 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.

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.
