Description: FARNESYL TRANSFERASE INHIBITING 6- [(SUBSTITUTED PHENYL)METHYL]-QUINOLINE AND QUTNAZOLINE DERIVATIVES The present invention is concerned with novel 6- [(substituted phenyl)methyl]-quinoline and quinazoline derivatives, the preparation thereof, pharmaceutical compositions comprising said novel compounds and the use of these compounds as a medicine as well as methods of treatment by administering said compounds. 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. A particular group of oncogenes is known as ras which have been identified in mammals, birds, insects, mollusks, plants, fungi and yeasts. The family of mammalian ras oncogenes consists of three major members ("isoforms") : H-ras, K-ras and N-r s oncogenes. These ras oncogenes code for highly related proteins genetically known as p21 ra,s . Once attached to plasma membranes, the mutant or oncogenic forms of p21 rΩ,s will provide a signal for the transformation and uncontrolled growth of malignant tumor cells. To acquire this transforming potential, the precursor of the p21 ra5 oncoprotein must undergo an enzymatically catalyzed farnesylation of the cysteine residue located in a carboxyl-terminal tetrapeptide. Therefore, inhibitors of the enzymes that catalyzes this modification, i.e. farnesyl transferase, will prevent the membrane attachment of τp21 ras and block the aberrant growth of røs-transformed tumors. Hence, it is generally accepted in the art that farnesyl transferase inhibitors can be very useful as anticancer agents for tumors in which ras contributes to transformation. Since 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 al., Science, vol 260, 1834 - 1837, 1993), it has been suggested that farnesyl tranferase inhibitors can be very useful against these types of cancer. In EP-0,371,564 there are described (lH-azol-1-ylmethyl) substituted quinoline and quinolinone derivatives which suppress the plasma elimination of retinoic acids. Some of these compounds also have the ability to inhibit the formation of androgens from progestines and/or inhibit the action of the aromatase enzyme complex. In WO 97/16443, WO 97/21701, WO 98/40383 and WO 98/49157, there are described 2-quinolone derivatives which exhibit farnesyl transferase inhibiting activity. WO 00/39082 describes a class of novel 1,2-annelated quinoline compounds, bearing a nitrogen- or carbon-linked imidazole, which show farnesyl protein transferase and geranylgeranyl transferase inhibiting activity. Other quinolone compounds having farnesyl transferase inhibiting activity are described in WO 00/12498, 00/12499 and 00/47574. Unexpectedly, it has been found that the present novel 6-[(substituted phenyl)methyl]- quinoline and quinazoline compounds show farnesyl protein transferase inhibiting activity.

With regard to process a), this can be effected as described for example in WO 97/21701 and WO98/49157 referred to above. Thus, the cyclisation may be effected for example by subjecting the compound of formula (II) to an acetylation reaction, e.g. by treatment with the anhydride of a carboxylic acid, e.g. acetic anhydride in a reaction- inert solvent, e.g. toluene, and subsequent reaction with a base such as potassium tert- butoxide in a reaction-inert solvent such as 1,2-dimethoxyethane. With regard to process b), this can also be effected as described for example in WO 97/21701 and WO98/49157 referred to above for the preparation of compounds in which R 7 is oxygen, for example by hydrolysis of an ether of formula (II) in which WI is d- 6 alkyloxy in an aqueous acid solution such hydrochloric acid . Alternatively a compound of formula (III) in which W 1 is a chloro radical can be used. With regard to process b), for the preparation of compounds in which R and R 7 together form a trivalent radical of formula (x-1) to (x-10), this can be effected as described for example in WO 00/39082 referred to above. For example, when W 1 is chloro, the compound of formula (III) can be reacted with an azide compound for example sodium azide to form a corresponding compound of formula (I) in which R 6 and R 7 together form a trivalent radical of formula (x-4). Alternatively, when W 1 is chloro, the compound of formula (El) can be reacted with aquous hydrazine to form a compound of formula (III) where W 1 is NHNH 2 which by reaction with sodium nitrite in acidic media form a corresponding compound of formula (I) in which R 6 and R 7 together form a trivalent radical of formula (x-4). With regard to process c), this can be effected for example by N-alkylating an intermediate of formula (IV), wherein W 2 is an appropriate leaving group such as, for example, chloro, bromo, methanesulfonyloxy or benzenesulfonyloxy, with an intermediate of formula (IVa) to form a a compound of formula (I) in which R 4 is a group of formula (c-1) represented by compounds of formula (I-a): (IV) (IVa) (l-a) The reaction can be performed in a reaction-inert solvent such as, for example, acetonitrile, and optionally in the presence of a suitable base such as, for example, sodium carbonate, potassium carbonate or triethylamine. Stirring may enhance the rate of the reaction. The reaction may conveniently be carried out at a temperature ranging between room temperature and reflux temperature. Also, compounds of formula (I-a) can be prepared by reacting an intermediate of formula (V) in which W 2 is hydroxy with an intermediate of formula (X), whereir oxygen or sulfur, such as, for example, a l,l'-carbonyldiimidazole. Said reaction may conveniently be conducted in a reaction-inert solvent, such as, e.g. tetrahydrofuran, optionally in the presence of a base, such as sodium hydride, and at a temperature ranging between room temperature and the reflux temperature of the reaction mixture. With regard to process d), this can be used to introduce the R 4 group, for example by reacting a compound of formula (V) in which R x is R 2 with an imidazole reagent to form a compound of formula (I) in which R 4 is a group of formula (c-2), or with a 3- mercapto-4-Cj:- 6 alkyl-l,2,4-triazole reagent to form the corresponding 3-mercapto-4- Cι- 6 alkyl-l,2,4-triazole derivative, which is optionally methylated to form the corresponding 3-methylmercapto derivative, and subsequently removing the 3- mercapto or 3-methylmercapto group to form a compound of formula (I) in which R 4 is a group of formula (c-3) in which R 18 is a Cι- 6 alkyl group; or with a 3-bromopyridyl group to form a compound of formula (I) in which R 4 is a group of formula (c-4). In 4 more detail, the compounds of formula (I) wherein R represents a radical of formula 3 17 (c-2), R is hydroxy and R is Ci_6alkyl, said compounds being referred to as compounds of formula (I-b-1) may be prepared by reacting an intermediate ketone of formula (V) with an intermediate of formula (III-l). Said reaction requires the presence of a suitable strong base, such as, for example, butyl lithium in an appropriate solvent, such as, for example, tetrahydrofuran, and the presence of an appropriate silane derivative, such as, for example, triethylchlorosilane. During the work-up procedure an intermediate silane derivative is hydrolyzed. Other procedures with protective groups analogous to silane derivatives can also be applied. 4 3 Also, the compounds of formula (I), wherein R is a radical of formula (c-2), R is 17 hydroxy and R is hydrogen, said compounds being referred to as compounds of formula (I-b-2) may be prepared by reacting an intermediate ketone of formula (V) with a intermediate of formula (ffl-2), wherein PG is a protective group such as, for example, a sulfonyl group, e.g. a dimethylamino sulfonyl group, which can be removed after the addition reaction. Said reaction is conducted analogously as for the preparation of compounds of formula (Tb-1), followed by removal of the protecting group PG, yielding compounds of formula (I-b-2). With regard to process e), this may be effected for example as described in WO 97/21701 referred to above, by reacting the nitrone of formula (VI) with the anhydride of a carboxylic acid, e.g. acetic anhydride, thus forming the corresponding ester on the 2-position of the quinoline moiety, which ester can then be hydrolysed in situ to the corresponding quinolinone using a base such potassium carbonate.Altematively the above nitrone can be reacted with tosyl chloride to prepare the corresponding tosylate which can then be hydrolysed in situ. Examples of the interconversion of one compound of formula (I) into a different compound of formula (I) include the following reactions:- a) compounds of formula (I-b) can be converted to compounds of formula (I-c), defined 4 3 as a compound of formula (I) wherein R is a radical of formula (c-2) and R is hydrogen, by submitting the compounds of formula (I-b) to appropriate reducing conditions, such as, e.g. stirring in acetic acid in the presence of formamide, or treatment with sodium borohydride/ trifluoroacetic acid. b) compounds of formula (I-b) can be converted to compounds of formula (I-f) wherein 3 R is halo, by reacting the compounds of formula (I-b) with a suitable halogenating agent, such as, e.g. thionyl chloride or phosphorus tribromide. Successively, the 11 12 compounds of formula (1-f) can be treated with a reagent of formula H-NR R in a reaction-inert solvent, thereby yielding compounds of formula (I-g). c) compounds of formula (I-b) can be converted into compounds of formula (I-g) for example by treatment with SOCl 2 , and then NH 3 /iPrOH, e.g. in a tetrahydrofuran solvent, or by treatment with acetic acid ammonium salt at a temperature ranging from 120 to 180°C, or by treatment with sulfamide at a temperature ranging from 120 to 180°C; d) compounds of formula (1-f) can be converted into compounds of formula (I-c) for example by treatment with SnCl 2 in the presence of concentrated HC1 in acetic acid at reflux; e) compounds of formula (I) in which >Y*-Y 2 represents a radical of formula (y-1) or (y-2) can be converted into corresponding compounds of formula (I) in which >Y -Y represents a radical of formula (y-3) or (y-4) respectively, by conventional reduction procedures for example hydrogenation or reduction by treatment with sodium borohydride in a suitable solvent, e.g. methanol. and vice versa by conventional oxidation procedures; e.g. oxidation with MnO 2 in a reaction-inert solvent, e.g. dichloromethane; f) compounds of formula (I) in which X is oxygen can be converted into corresponding compounds of formula (I) in which X is sulphur with a reagent such as phosphorus pentasulfide or Lawesson's reagent in a suitable solvent such as, for example, pyridine. The compounds of formula (I) may also be converted into each other via art-known reactions or functional group transformations. A number of such transformations are already described hereinabove. Other examples are hydrolysis of carboxylic esters to the corresponding carboxylic acid or alcohol; hydrolysis of amides to the corresponding carboxylic acids or amines; hydrolysis of nitriles to the corresponding amides; amino groups on imidazole or phenyl may be replaced by a hydrogen by art-known diazotation reactions and subsequent replacement of the diazo-group by hydrogen; alcohols may be converted into esters and ethers; primary amines may be converted into secondary or tertiary amines; double bonds may be hydrogenated to the corresponding single bond; an iodo radical on a phenyl group may be converted in to an ester group by carbon monoxide insertion in the presence of a suitable palladium catalyst. The intermediates and starting materials used in the above-described processes my be prepared in conventional manner using procedures known in the art for example as described in the above-mentioned patent specifications WO 97/16443, WO 97/21701, WO 98/40383, WO 98/49157 and WO 00/39082. The compounds of formula (I) and some of the intermediates have at least one stereogenic center in their structure. This stereogenic center may be present in a R or a S configuration. The compounds of formula (I) as prepared in the hereinabove described processes are generally racemic mixtures of enantiomers which can be separated from one another following art-known resolution procedures. The racemic compounds of formula (I) may be converted into the corresponding diastereomeric salt forms by reaction with a suitable chiral acid. Said diastereomeric salt forms are subsequently separated, for example, by selective or fractional crystallization and the enantiomers are liberated therefrom by alkali. An alternative manner of separating the enantiomeric forms of the compounds of formula (I) involves liquid chromatography using a chiral stationary phase. Said pure stereochemically isomeric forms may also be derived from the corresponding pure stereochemically isomeric forms of the appropriate starting materials, provided that the reaction occurs stereospecifically. Preferably if a specific stereoisomer is desired, said compound will be synthesized by stereospecific methods of preparation. These methods will advantageously employ enantiomerically pure starting materials. The compounds of formula (I), the pharmaceutically acceptable acid addition salts and stereoisomeric forms thereof have valuable pharmacological properties in that they have a potent farnesyl protein transferase (FPTase) inhibitory effect. This invention provides a method for inhibiting the abnormal growth of cells, including transformed cells, by administering an effective amount of a compound of the 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 of another gene; (3) benign and malignant cells of other proliferative diseases in which aberrant ras activation occurs. Furthermore, it has been suggested in literature that ras oncogenes not only contribute to the growth of tumors in vivo by a direct effect on tumor cell growth but also indirectly, i.e. by facilitating tumor-induced angiogenesis (Rak. J. et al, Cancer Research, 55, 4575-4580, 1995). Hence, pharmacologically targeting mutant ras oncogenes could conceivably suppress solid tumor growth in vivo, in part, by inhibiting tumor-induced angiogenesis. This invention also provides a method for inhibiting tumor growth by administering an effective amount of a compound of the present invention, to a subject, e.g. a mammal (and more particularly a human) in need of such treatment. In particular, this invention provides a method for inhibiting the growth of tumors expressing an activated ras oncogene by the administration of an effective amount of the compounds of the present invention. Examples of tumors which may be inhibited, but are not limited to, lung cancer (e.g. adenocarcinoma and including non-small cell lung cancer), 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), prostate cancer including the advanced disease, hematopoietic tumors of lymphoid lineage (e.g. acute lymphocytic leukemia, B-cell lymphoma, Burkitt's lymphoma), myeloid leukemias (for example, acute myelogenous leukemia (AML)), thyroid follicular cancer, myelodysplastic syndrome (MDS), tumors of mesenchymal origin (e.g. fibrosarcomas and rhabdomyosarcomas), melanomas, teratocarcinomas, neuroblastomas, gliomas, benign tumor of the skin (e.g. keratoacanthomas), breast carcinoma (e.g. advanced breast cancer), kidney carcinoma, ovary carcinoma, bladder carcinoma and epidermal carcinoma. This invention may also provide a method for inhibiting proliferative diseases, both benign and malignant, wherein ras proteins are aberrantly activated as a result of oncogenic mutation in genes. With said inhibition being accomplished by the administration of an effective amount of the compounds described herein, to a subject in need of such a treatment. For example, the benign proliferative disorder neuro- fibromatosis, or tumors in which ras is activated due to mutation or overexpression of tyrosine kinase oncogenes, may be inhibited by the compounds of this invention. The compound according to the invention can be used for other therapeutic purposes, for example: a) the sensitisation of tumors to radiotherapy by administering the compound according to the invention before, during or after irradiation of the tumor for treating cancer, for example as described in WO 00/01411; b) treating athropathies such as rheumatoid arthritis, osteoarthritis, juvenile arthritis, gout, polyarthritis, psoriatic arthritis, ankylosing spondylitis and systemic lupus erythematosus, for example as described in WO 00/01386; c) inhibiting smooth muscle cell proliferation including vascular proliferative disorders, atherosclerosis and restenosis, for example as described in WO 98/55124; d) treating inflammatory conditions such as ulcerative colitis, Crohn's disease, allergic rhinitis, graft vs host disease, conjunctivitis, asthma, ARDS, Behcets disease, transplant rejection, uticaria, allergic dermatitis, alopecia areata, scleroderma, exanthem, eczema, dermatomyositis, acne, diabetes, systemic lupus erythematosis, Kawasaki's disease, multiple sclerosis, emphysema, cystic fibrosis and chronic bronchitis; e) treating endometriosis, uterine fibroids, dysfunctional uterine bleeding and endometrial hyperplasia; f) treating ocular vascularisation including vasculopathy affecting retinal and choroidal vessels; g) treating pathologies resulting from heterotrimeric G protein membrane fixation including diseases related to following biological functions or disorders; smell, taste, light, perception, neurotransmission, neurodegeneration, endocrine and exocrine gland functioning, autocrine and paracrine regulation, blood pressure, embryogenesis, viral infections, immunological functions, diabetes, obesity; h) inhibiting viral morphogenesis for example by inhibiting the prenylation or the post-prenylation reactions of a viral protein such as the large delta antigen of hepatitis D virus; and the treatment of HTV infections; i) treating polycystic kidney disease; j) suppressing induction of inducible nitric oxide including nitric oxide or cytokine mediated disorders, septic shock, inhibiting apoptosis and inhibiting nitric oxide cytotoxicity; k) treating malaria. Hence, the present invention discloses the compounds of formula (I) for use as a medicine as well as the use of these compounds of formula (I) for the manufacture of a medicament for treating one or more of the above mentioned conditions. For the treatment of the above conditions, the compound of the invention may be advantageously employed in combination with one or more other medicinal agents such as anti-cancer agents for example selected from platinum coordination compounds for example cisplatin or carboplatin, taxane compounds for example paclitaxel or docetaxel, camptothecin compounds for example irinotecan or topotecan, anti-tumor vinca alkaloids for example vinblastine, vincristine or vinorelbine, anti-tumor nucleoside derivatives for example 5- fluorouracil, gemcitabine or capecitabine, nitrogen mustard or nitrosourea alkylating agents for example cyclophosphamide, chlorambucil, carmustine or lomustine, anti- tumor anthracychne derivatives for example daunorubicin, doxorubicin or idarubicin; HER2 antibodies for example trastzumab; and anti-tumor podophyllotoxin derivatives for example etoposide or teniposide; and antiestrogen agents including estrogen receptor antagonists or selective estrogen receptor modulators preferably tamoxifen, or alternatively toremifene, droloxifene, faslodex and raloxifene, or aromatase inhibitors such as exemestane, anastrozole, letrazole and vorozole. For the treatment of cancer the compounds according to the present invention can administered to a patient as described above in conjunction with irradiation; such treatment is may be especially beneficial as farnesyl transferase inhibitors can act as radiosensitisers for example as described in International Patent Specification WO 00/01411, enhancing the therapeutic effect of such irradiation. Irradiation means ionizing radiation and in particular gamma radiation, especially that emitted by linear accelerators or by radionuclides that are in common use today. The irradiation of the tumor by radionuclides can be external or internal. Preferably, the administration of the farnesyl transferase inhibitor commences up to one month, in particular up to 10 days or a week, before the irradiation of the tumor. Additionally, it is advantageous to fractionate the irradiation of the tumor and maintain the administration of the farnesyl transferase inhibitor in the interval between the first and the last irradiation session. The amount of farnesyl protein transferase inhibitor, the dose of irradiation and the intermittence of the irradiation doses will depend on a series of parameters such as the type of tumor, its location, the patients' reaction to chemo- or radiotherapy and ultimately is for the physician and radiologists to determine in each individual case. The present invention also concerns a method of cancer therapy for a host harboring a tumor comprising the steps of - administering a radiation-sensitizing effective amount of a farnesyl protein transferase inhibitor according to the invention before, during or after - administering radiation to said host in the proximity to the tumor. In view of their useful pharmacological properties, the subject compounds may be formulated into various pharmaceutical forms for administration purposes. To prepare the pharmaceutical compositions of this invention, an effective amount of a particular compound, in base or acid addition salt form, as the active ingredient is combined in intimate admixture with a pharmaceutically acceptable carrier, which carrier may take a wide variety of forms depending on the form of preparation desired for administration. These pharmaceutical compositions are desirably in unitary dosage form suitable, preferably, for administration orally, rectally, percutaneously, or by parenteral injection. For example, in preparing the compositions in oral dosage form, any of the usual pharmaceutical media may be employed, such as, for example, water, glycols, oils, alcohols and the like in the case of oral liquid preparations such as suspensions, syrups, elixirs and solutions; or solid carriers such as starches, sugars, kaolin, lubricants, binders, disintegrating agents and the like in the case of powders, pills, capsules and tablets. Because of their ease in administration, tablets and capsules represent the most advantageous oral dosage unit form, in which case solid pharmaceutical carriers are obviously employed. For parenteral compositions, the carrier will usually comprise sterile water, at least in large part, though other ingredients, to aid solubility for example, may be included. Injectable solutions, for example, may be prepared in which the carrier comprises saline solution, glucose solution or a mixture of saline and glucose solution. Injectable suspensions may also be prepared in which case appropriate liquid carriers, suspending agents and the like may be employed. In the compositions suitable for percutaneous administration, the carrier optionally comprises a penetration enhancing agent and/or a suitable wetting agent, optionally combined with suitable additives of any nature in minor proportions, which additives do not cause a significant deleterious effect to the skin. Said additives may facilitate the administration to the skin and/or may be helpful for preparing the desired compositions. These compositions may be administered in various ways, e.g., as a transdermal patch, as a spot-on, as an ointment. It is especially advantageous to formulate the aforementioned pharmaceutical compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used in the specification and claims herein refers to physically discrete units suitable as unitary dosages, each unit containing a predetermined quantity of active ingredient calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. Examples of such dosage unit forms are tablets (including scored or coated tablets), capsules, pills, powder packets, wafers, injectable solutions or suspensions, teaspoonfuls, tablespoonfuls and the like, and segregated multiples thereof. Those skilled in the art could easily determine the effective amount from the test results presented hereinafter. In general it is contemplated that an effective amount would be from 0.01 mg/kg to 100 mg/kg body weight, and in particular from 0.05 mg/kg to 10 mg/kg body weight. It may be appropriate to administer the required dose as two, three, four or more sub-doses at appropriate intervals throughout the day. Said sub-doses may be formulated as unit dosage forms, for example, containing 0.5 to 500 mg, and in particular 1 mg to 200 mg of active ingredient per unit dosage form. The following examples are provided for purposes of illustration.
