Description

~-Carboxyaryl substituted diphenyl ureas as raf kinase inhibitors Field of the Invention This invention relates to the use of a group of aryl ureas in treating raf mediated diseases, and pharmaceutical compositions for use in such therapy.
Background of the Invention The p2lras oncogene is a major contributor to the development and progression of human solid cancers and is mutated in 30% of all human cancers (Bolton et al. Ann. Rep.
Med. Chem. 1994, 29, 165-74; Bos. Cancer Res. 1989, 49, 4682-9). In its normal, unmutated form, the ras protein is a key element of the signal transduction cascade directed by growth factor receptors in almost all tissues (Avruch et al.
Trends Biochem. Sci. 1994, 19, 279-83). Biochemically, ras is a guanine nucleotide binding protein, and cycling between a GTP-bound activated and a GDP-bound resting form is strictly controlled by ras' endogenous GTPase activity and other regulatory proteins. In the ras mutants in cancer cells, the endogenous GTPase activity is alleviated and, therefore, the protein delivers constitutive growth signals to downstream effectors such as the enzyme raf kinase. This leads to the cancerous growth of the cells which carry these mutants (Magnuson et al. Semin. Cancer Biol. 1994, 5, 247-53). It has been shown that inhibiting the effect of active ras by inhibiting the raf kinase signaling pathway by administration of deactivating antibodies to raf kinase or by co-expression of dominant negative raf kinase or dominant negative MEK, the substrate of raf kinase, leads to the reversion of transformed cells to the normal growth phenotype (see:
Daum et al. Trends Biochem. Sci. 1994, 19, 474-80; Fridman et al. J. Biol.
Chem. 1994, 269, 30105-8. Kolch et al. (Nature 1991, 349, 426-28) have further indicated that inhibition of raf expression by antisense RNA blocks cell proliferation in membrane-associated oncogenes.
Similarly, inhibition of raf kinase (by antisense oligodeoxynucleotides) has been correlated in vitro and in vivo with inhibition of the growth of a variety of human tumor types (Monia et al., Nat. Med. 1996, 2, 668-75).
Summary of the Invention 1o The present invention provides compounds which are inhibitors of the enzyme raf kinase.
Since the enzyme is a downstream effector of p21'as, the inhibitors are useful in pharmaceutical compositions for human or veterinary use where inhibition of the raf kinase pathway is indicated, e.g., in the treatment of tumors and/or cancerous cell growth mediated by raf kinase. In particular, the compounds are useful in the treatment of human or animal solid cancers, e.g., murine cancer, since the progression of these cancers is dependent upon the ras protein signal transduction cascade and therefore susceptible to treatment by interruption of the cascade, i.e., by inhibiting raf kinase. Accordingly, the compounds of the invention are useful in treating cancers, including solid cancers, such as, for example, carcinomas (e.g., of the lungs, pancreas, thyroid, bladder or colon), myeloid disorders (e.g., 2o myeloid leukemia) or adenomas (e.g., villous colon adenoma).
The present invention therefore provides compounds generally described as aryl ureas, including both aryl and heteroaryl analogues, which inhibit the raf kinase pathway. The invention also provides a method for treating a raf mediated disease state in humans or mammals. Thus, the invention is directed to compounds which inhibit the enzyme raf kinase and also compounds, compositions and methods for the treatment of cancerous cell growth mediated by raf kinase wherein a compound of Formula I is administered or pharmaceutically acceptable salt thereof.

A number of the compounds of Formula I possess asymmetric carbons and can therefore exist in racemic and optically active forms. Methods of separation of enantiomeric and diastereomeric mixtures are well known to one skilled in the art. The present invention encompasses any isolated racemic or optically active form of compounds described in Formula I which possess raf inhibitory activity.
6b General Preparative Methods The compounds of Formula I may be prepared by the use of known chemical reactions and procedures, some from starting materials which are commercially available.
Nevertheless, general preparative methods are provided below to aid one skilled in the art in synthesizing these compounds, with more detailed examples being provided in the Experimental section which follows.
Substituted anilines may be generated using standard methods (March. Advanced Organic Chemistry, 3'd Ed.; John Wiley: New York (1985). Larock. Comprehensive Organic Transformations; VCH Publishers: New York (1989)). As shown in Scheme I, aryl amines are commonly synthesized by reduction of nitroaryls using a metal catalyst, such as Ni, Pd, or Pt, and HZ or a hydride transfer agent, such as formate, cyclohexadiene, or a borohydride (Rylander. Hydrogenation Methods; Academic Press: London, UK (1985)).
Nitroaryls may also be directly reduced using a strong hydride source, such as LiAlH4 (Seyden-Penne.
Reductions by the Alumino- and Borohydrides in Organic Synthesis; VCH
Publishers: New York ( 1991 )), or using a zero valent metal, such as Fe, Sn or Ca, often in acidic media. Many methods exist for the synthesis of nitroaryls (March. Advanced Organic Chemistry, 3'd Ed.;
John Wiley: New York (1985). Larock. Comprehensive Organic Transformations;
VCH
Publishers: New York (1989)).
H21 catalyst (eg. Ni, Pd, Pt) ArN02 ~H ~ ArNH2 M(0) (eg. Fe, Sn, Ca) Scheme I Reduction of Nitroaryls to Aryl Amines Nitroaryls are commonly formed by electrophilic aromatic nitration using HNO:, or an alternative NO,' source. Nitroaryls may be further elaborated prior to reduction. Thus.
nitroaryls substituted with Ar-H ArN02 potential leaving groups (e.g. F, Cl, Br, etc.) may undergo substitution reactions on treatment with nucleophiles, such as thiolate (exemplified in Scheme II) or phenoxide.
Nitroaryls may also undergo Ullman-type coupling reactions (Scheme II).

For example, nitroaryl electrophiles, such as nitroaryl bromides, iodides or triflates, undergo palladium mediated cross coupling reactions with aryl nucleophiles, such as arylboronic acids (Suzuki reactions, exemplified below), aryltins (Stifle reactions) or arylzincs (Negishi reaction) to afford the biaryl (5).

Either nitroaryls or anilines may be converted into the corresponding arenesulfonyl chloride (7) on treatment with chlorosulfonic acid. Reaction of the sulfonyl chloride with a fluoride source, such as KF then affords sulfonyl fluoride (8). Reaction of sulfonyl fluoride 8 with trimethylsilyl trifluoromethane in the presence of a fluoride source, such as tris(dimethylamino)sulfonium difluorotrimethylsiliconate (TASF) leads to the corresponding trifluoromethylsulfone (9). Alternatively, sulfonyl chloride 7 may be reduced to the arenethiol ( 10), for example with zinc amalgum. Reaction of thiol 10 with CHC1F~ in the presence of base gives the difluoromethyl mercaptam (11), which may be oxidized to the sulfone (12) with any of a variety of oxidants, including Cr03-acetic anhydride (Sedova et al.

Scheme III Selected Methods of Fluorinated Aryl Sulfone Synthesis As shown in Scheme IV, non-symmetrical urea formation may involve reaction of an aryl isocyanate (14) with an aryl amine (13). The heteroaryl isocyanate may be syntnesizea from a heteroaryl amine by treatment with phosgene or a phosgene equivalent, such as trichloromethyl chloroformate (diphosgene), bis(trichloromethyl) carbonate (triphosgene), or !o N.N'-carbonyldiimidazole (CDI). The isocyanate may also be derived from a heterocyclic carboxylic acid derivative, such as an ester, an acid halide or an anhydride by a Curtius-type rearrangement. Thus, reaction of acid derivative 16 with an azide source, followed by rearrangement affords the isocyanate. The corresponding carboxylic acid ( 17) may also be subjected to Curtius-type rearrangements using diphenylphosphoryl azide (DPPA) or a similar reagent.

Scheme IV Selected Methods of Non-Symmetrical Urea Formation 5 Finally, ureas may be further manipulated using methods familiar to those skilled in the art.
The invention also includes pharmaceutical compositions including a compound of Formula I, and a physiologically acceptable carrier.
to The compounds may be administered orally, topically, parenterally, by inhalation or spray or rectally in dosage unit formulations. The term 'administration by injection' includes intravenous, intramuscular, subcutaneous and parenteral injections, as well as use of infusion techniques. One or. more compounds may be present in association with one or more non-toxic pharmaceutically acceptable carriers and if desired other active ingredients.
Compositions intended for oral use may be prepared according to any suitable method known to the art for the manufacture of pharmaceutical compositions. Such compositions may contain one or more agents selected from the group consisting of diluents, sweetening agents, flavoring agents, coloring agents and preserving agents in order to provide palatable 'u preparations. Tablets contain the active ingredient in admixture with non-toxic pharmaceutically acceptable excipients which are suitable for the manufacture of tablets.
These excipients may be, for example, inert diluents, such as calcium carbonate, sodium IU

carbonate, lactose, calcium phosphate or sodium phosphate; granulating and disintegrating agents, for example, corn starch, or alginic acid; and binding agents, for example magnesium stearate, stearic acid or talc. The tablets may be uncoated or they may be coated by known techniques to delay disintegration and adsorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monostearate or glyceryl distearate may be employed. These compounds may also be prepared in solid, rapidly released form.
Formulations for oral use may also be presented as hard gelatin capsules wherein the active to ingredient is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin, or as soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium, for example peanut oil, liquid paraffin or olive oil.
Aqueous suspensions contain the active materials in admixture with excipients suitable for the manufacture of aqueous suspensions. Such excipients are suspending agents, for example sodium carboxymethylcellulose, methylcellulose, hydroxypropyl methylcellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia; dispersing or wetting agents may be a naturally occurring phosphatide, for example, lecithin, or condensation products or an alkylene oxide with fatty acids, for example polyoxyethylene stearate, or condensation 2o products of ethylene oxide with long chain aliphatic alcohols, for example heptadecaethylene oxycetanol, or condensation products of ethylene oxide with partial esters derived from fatty acids and hexitol such as polyoxyethylene sorbitol monooleate, or condensation products of ethylene oxide with partial esters derived from fatty acids and hexitol anhydrides, for example polyethylene sorbitan monooleate. The aqueous suspensions may also contain one or more preservatives, for example ethyl, or n-propyl p-hydroxybenzoate, one or more coloring agents, one or more flavoring agents, and one or more sweetening agents, such as sucrose or saccharin.
Dispersible powders and granules suitable for preparation of an aqueous suspension by the :u addition of water provide the active ingredient in admixture with a dispersing or wetting agent, suspending agent and one or more preservatives. Suitable dispersing or wetting agents and suspending agents are exemplified by those already mentioned above.
Additional excipients, for example, sweetening, flavoring and coloring agents, may also be present.
The compounds may also be in the form of non-aqueous liquid formulations, e.g., oily suspensions which may be formulated by suspending the active ingredients in a vegetable oil, for example arachis oil, olive oil, sesame oil or peanut oil, or in a mineral oil such as liquid paraffin. The oily suspensions may contain a thickening agent, for example beeswax, hard paraffin or cetyl alcohol. Sweetening agents such as those set forth above, and flavoring agents may be added to provide palatable oral preparations. These compositions may be to preserved by the addition of an anti-oxidant such as ascorbic acid.
Pharmaceutical compositions of the invention may also be in the form of oil-in-water emulsions. The oily phase may be a vegetable oil, for example olive oil or arachis oil, or a mineral oil, for example liquid paraffin or mixtures of these. Suitable emulsifying agents may be naturally-occurring gums, for example gum acacia or gum tragacanth, naturally-occurnng phosphatides, for example soy bean, lecithin, and esters or partial esters derived from fatty acids and hexitol anhydrides, for example sorbitan monooleate, and condensation products of the said partial esters with ethylene oxide, for example polyoxyethylene sorbitan monooleate. The emulsions may also contain sweetening and flavoring agents.
Syrups and elixirs may be formulated with sweetening agents, for example glycerol, propylene glycol, sorbitol or sucrose. Such formulations may also contain a demulcent, a preservative and flavoring and coloring agents.
The compounds may also be administered in the form of suppositories for rectal administration of the drug. These compositions can be prepared by mixing the drug with a suitable non-irntating excipient which is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such materials include cocoa butter and polyethylene glycols.
