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.

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 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.

This invention provides a method for inhibiting or treating the abnormal growth of cells, including transformed cells, by administering an 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.

This invention also provides a method for inhibiting or treating tumor growth by administering an 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 of the above described compounds. Examples of 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.

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 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, lck, and fyn), may be inhibited or treated by the tricyclic compounds described herein.

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.

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

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.

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.

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.

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.

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.

Compounds of the invention may be prepared according to the procedures described in WO95/10516 published Apr. 20, 1995, WO96/31478 published Oct. 10, 1996, WO97/23478 published Jul. 3, 1997, U.S. Pat. No. 5,719,148 issued Feb. 17, 1998, and copending application Ser. No. 09/094,687 filed Jun. 15, 1998 (see also WO98/57960 published Dec. 23, 1998); the disclosures of each being incorporated herein by reference thereto; and according to the procedures described below.

Compounds of the invention can be prepared according to the reaction schemes described below.

In Scheme 1, R 11 and R 12 are preferably methyl when H is bound to the amide nitrogen (i.e., when R 8 in formula 1.0 is H), e.g., 41.0, and are preferably H when the amide nitrogen is substituted (i.e., R 8 in formula 1.0 is other than H), e.g., 41.1. Those skilled in the art will appreciate that other acylating agents can be used in place of cyclohexyl isocyanate to obtain compounds having different groups bound to the carbonyl group that is bound to the piperazine nitrogen. Those skilled in the art will also appreciate that other esters can be used in place of compound 31.0 to obtain compounds having different carbon chains between the imidazole ring and the C(O)NH-group.

Compounds of 41.0 can be prepared beginning with the conjugate addition of imidazole (2-, 4-, and/or 5-substituted) to an appropriately substituted acrylate 31.0 in EtOH at reflux or neat at 90° C. Standard LAH reduction of the ester 32.0 gives the alcohol 33.0 which can be converted to the phthalimide 35.0 via the Mitsunobu reaction. Removal of the phthalimido group with hydrazine in EtOH at reflux gives amine 36.0. This amine readily opens the piperazine anhydride 37.0 with the evolution of CO 2 and subsequent reaction with isocyanates gives the one pot conversion to urea 38.0. Removal of the BOC-group with 50% TFA at room temperature gives the salt 39.0, which can be readily coupled to the tricyclic chloride 40.0 to give the desired product 41.0.

In Scheme 1, and the Schemes that follow, Y represents C, N or N + O − such that there can only be 0-2 Y substituents that are independently selected from N or N + O − . R A represents the optional substituents in the imidazole ring that are defined for imidazole ring 4.0 above. R B represents the optional substituents defined above for the aryl or heteroaryl groups for R 8 .

For example, following Reaction Scheme 1, wherein R 11 and R 12 are methyl, and using compound 42.0 (see Preparative Example 40 in WO95/10516 published Apr. 20, 1995) can be obtained.

The synthesis of the intermediate amine 51.0 begins with the alkylation of the sodium salt of imidazole (or substituted imidazole) 44.0 with 45.0 at 90° C. Standard LAH reduction of the ester 46.0 gives the alcohol 47.0. Tosylation of 47.0 and displacement of tosylate with potassium phthalimide 49.0 in DMF at 90° C. gives the phthalimido derivative 50.0 which can be readily converted to the amine 51.0 with hydrazine in refluxing EtOH. Compounds wherein R 8 ≠H can be prepared as described in Scheme 1.

Similar to the procedure set forth in Scheme 1 for 36.0 and 36.1, 51.0 and 51.1 in Scheme 2 are reacted to form compounds of formula 1.0. In Scheme 2, R 11 and R 12 are preferably methyl when H is bound to the amide nitrogen (i.e., when R 8 in formula 1.0 is H), and are preferably H when the amide nitrogen is substituted (i.e., R 8 in formula 1.0 is other than H).

Compound (±) 52.0 is resolved following procedures similar to those disclosed in WO97/23478 (published Jul, 3. 1997).

The reagents used in Reaction Scheme 3 are: Reaction Step a: Isatoic anhydride/methylene chloride; Reaction Step b: sodium nitrite/hydrochloric acid/methanol/cuprous chloride; Reaction Step c: (i) aq. hydrochloric acid/methanol/reflux (ii) sodium hydroxide/sodium cyanide; Reaction Step d: conc. hydrochloric acid/reflux.; and Reaction Step e: di-tert.butyldicarbonate/-sodium hydroxide/tetrahydrofuran.

In Scheme 5, R 30 represents:

In Scheme 6, the procedure set forth in Scheme 4 is followed, but using

instead of

to obtain the corresponding urea (—C(O)NHR 20 ), amide (—C(O)CH 2 R 20 or —C(O)R 20 ), sulfonamide (—SO 2 R 20 ) or carbamate (—C(O)OR 20 ) products, wherein n is 0, can be prepared. Similarly, using

(obtained from XI following the procedures in Scheme 4), instead of

in Scheme 4 and 5 produces the corresponding ureas, amides, sulfonamides and carbamates wherein n is 0.

Those skilled in the art will appreciate that in Schemes 1, 2 and 4-6, other aldehydes can be used in place of

to obtain the other substituents for R 8 in formula 1.0.

Those skilled in the art will also appreciate that using

instead of

in Schemes 4 and 5, and using

instead of

in Scheme 6 will provide the corresponding compounds wherein the imidazole is bound to the alkyl chain by a ring carbon.

Reaction Scheme 7 (R 9 and R 10 Are Other Than H)

In Scheme 7, the alcohol 33.0 can be oxidized under standard conditions to give the aldehyde. Addition of the corresponding Grignard of R 9 gives the alcohol which can be carried on to amine as in Scheme 1 or subject to reoxidation to the ketone followed by Grignard addition of R 10 . In the case where R 9 ═R 10 , the ester 32.0 (Scheme 1) can be used as the electrophile with 2 equivalents of the appropriate Grignard reagent being added.

Reaction Scheme 8 (R 9 and R 10 Are Other Than H, C-Linked Imidazole)

In Scheme 8, the nitrile may be reduced with DIBAL-H to the aldehyde. Similar to the procedure in Scheme 7, the aldehyde can then be treated with the appropriate Grignard reagent to give the alcohol. There can be an additional round of oxidation and Grignard addition to give the R 9 , R 10 disubstituted derivatives with either R 9 =R 10 or R 9 ·R 10 . The resulting alcohol may be converted to the amine by the methodology shown in either Schemes 1 or 2.

ASSAYS

FPT IC 50 (inhibition of farnesyl protein transferase, in vitro enzyme assay) and COS Cell IC 50 (Cell-Based Assay) were determined following the assay procedures described in WO 95/10516, published Apr. 20, 1995. GGPT IC 50 (inhibition of geranylgeranyl protein transferase, in vitro enzyme assay), Cell Mat Assay, and anti-tumor activity (in vivo anti-tumor studies) could be determined by the assay procedures described in WO95/10516. The disclosure of WO95/10516 is incorporated herein by reference thereto.

Additional assays can be carried out by following essentially the same procedure as described above, but with substitution of alternative indicator tumor cell lines in place of the T24-BAG cells. The assays can be conducted using either DLD-1-BAG human colon carcinoma cells expressing an activated K-ras gene or SW620-BAG human colon carcinoma cells expressing an activated K-ras gene. Using other tumor cell lines known in the art, the activity of the compounds of this invention against other types of cancer cells could be demonstrated.

Soft Agar Assay:

Anchorage-independent growth is a characteristic of tumorigenic cell lines. Human tumor cells can be suspended in growth medium containing 0.3% agarose and an indicated concentration of a farnesyl transferase inhibitor. The solution can be overlayed onto growth medium solidified with 0.6% agarose containing the same concentration of farnesyl transferase inhibitor as the top layer. After the top layer is solidified, plates can be incubated for 10-16 days at 37° C. under 5% CO 2 to allow colony outgrowth. After incubation, the colonies can be stained by overlaying the agar with a solution of MTT (3-[4,5-dimethyl-thiazol-2-yl]-2,5-diphenyltetrazolium bromide, Thiazolyl blue) (1 mg/mL in PBS). Colonies can be counted and the IC 50 's can be determined.
