ω-CARBOXYARYL SUBSTITUTED DIPHENYL UREAS AS RAF KINASE INHIBITORS as a rA kinase inhibitor

Cross Reference to Related Application

This application is part of an ongoing application of 09 / 257,266, filed February 25, 1999, and 60 / 115,877, filed January 13, 1999.

The present invention relates to the use of aryl urea groups to treat raf mediated diseases and pharmaceutical compositions for use in such therapies.

The p21 ^ras tumor gene is a major contributing factor in the development and progression of human solid cancers and variates in 30% of all human cancers (Bolton et al ., Ann. Rep. Med. Chem . 1994, 29 , 165-® Bos. Cancer Res 1989, 49 , 4682-9). The standard, unmutated form of ras protein is the answer to the signal transduction cascade dominated by growth factor receptors in almost all tissues (Avruch et al. , Trends Biochem. Sci . 1994, 19 , 279-83). ). Biochemically, ras is a guanine nucleotide that binds to a protein, and the circulatory movement between activated GTP-binding and resting GDP-binding forms is tightly regulated by ras' endogenous GTPase activity and other regulatory proteins. In the ras variant of cancer cells, endogenous GTPase activity is attenuated, thus the protein carries constitutive growth signals to sub-effectors such as the enzyme raf kinase. This allows cells carrying these strains to grow cancerous (Magnuson et al . , Semin. Cancer Biol . 1994, 5 , 247-53). It is known to inhibit the effects of active ras by administering an inactive antibody to raf kinase or co-expressing dominant negative raf kinase or dominant negative MEK to block the signaling pathway of raf kinase. Substrates of raf kinase return transformed cells to phenotypes of standard growth (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, 426-28) further pointed out that inhibiting raf expression by antisense RNA interferes with cell proliferation in membrane-bound tumor genes. Similarly, inhibition of raf kinase (by antisense oligodeoxynucleotides) is associated with growth inhibition of various human tumors in vitro and in vivo (Monia et al . , Nat. Med . 1996, 2, 668-75).

Summary of the Invention
The present invention provides compounds that inhibit the enzyme raf kinase. Because this enzyme is a sub- ^affector of p21 ^ras , the inhibitor is useful as a pharmaceutical composition for human or veterinary use by inhibiting the raf kinase pathway, such as in the treatment of tumors and / or in cancer cell growth by raf kinase mediated. . Specifically, since the progression of these cancers depends on the transducing cascade of ras protein signals, and thus can be treated by interfering with the cascade, i.e. inhibiting raf kinase, the present compositions can be used for human or animal solid cancers such as rats.

General manufacturing method

Compounds of formula 1 may be prepared using conventional chemical reactions and methods, and some of the starting materials are commercially available. Nevertheless, general methods of preparation are provided to assist those skilled in the art in synthesizing these compounds, and the following examples provide more detailed embodiments.

To produce a substituted aniline using standard methods ^{(March Advanced Organic Chemistry, 3 rd} Ed .; John Wiely: New York (1985) Larock Comprehensive Organic Transformations; VCH Publishers:... New York (1989)). As indicated in Scheme 1, aryl amines are generally prepared by reducing nitroaryl using metal catalysts such as Ni, Pd or Pt and H ₂ or hydride transfer agents such as formate, cyclohexadiene or borohydride. (Rylander, Hydrogenation Methods ; Academic Press: London, UK (1985)). Nitroaryl is also often used in acidic media, using strong hydride sources such as LiAlH ₄ (Seyden-Penne. Reduction by the Alumino- and Borohydrides in Organic Synthesis ; VCH Publishers: New York (1991)), zero- valent metals, For example, it can be directly reduced using Fe, Sn or Ca. There are many ways to synthesize nitro aryl ^{(March Advanced Organic Chemistry, 3 rd} Ed .; John Wiley: New York (1985) Larock Comprehensive Organic Transformation; VCH Publishers:... New York (1989)).

Reduction of nitroaryl to aryl amine

Nitroaryls are produced by electrophilic aromatic nitration, generally using HNO ₃ or an optional NO ₂ − source. Nitroaryl can be further refined prior to reduction. Thus, nitroaryl substituted with potential leaving groups (eg, F, Cl, Br, etc.)

Substitution reactions can be achieved by treatment with nucleophiles such as thiolates (exemplified in Scheme 2) or phenoxide. Nitroaryl may also be subjected to Ullman-type coupling reactions (Scheme 2).

Selected nucleophilic aromatic substitutions using nitroaryl

Nitroaryl can also be cross-coupled via a transition metal. For example, nitroaryl electrophiles such as nitroaryl bromide, iodine or triflate can be prepared, for example, nucleophiles such as arylboronic acid (Suzuki reaction, illustrated below), aryltin (Stille reaction) or arylzinc (Negishi reaction). And a cross-coupling reaction via palladium to obtain biaryl (5).

Nitroaryl or aniline can be converted to the corresponding arerensulfonyl chloride (7) by treatment with chlorosulfonic acid. Sulfonyl chloride is then reacted with a fluoride source such as KF to give sulfonyl fluoride (8). Sulfonyl fluoride is reacted with trimethylsilyl trifluoromethane in the presence of a fluoride source such as tris (dimethylamino) sulfonium difluorotrimethylsiliconate (TASF) to give the corresponding trifluoromethylsulphone (9) . Optionally, the sulfonyl chloride (7) can be reduced to arehenthiol (10), for example using zinc amalgam. Thiol 10 can be reacted with CHClF _{2 in the} presence of a base to give difluoromethyl mercaptam (11), which can be oxidized to sulfone (12) using any of a variety of oxidants including CrO ₃ -acetic anhydride (Sedova Et al . , Zh. Org.Khim . 1970, 6, (568)).

Selected Methods of Fluorinated Aryl Sulfone Synthesis

As shown in Scheme 4, asymmetric urea formation will include the reaction of aryl isocyanate (14) with aryl amine (13). Heteroaryl isocyanates are heteroaryl amines equivalent to phosgene or phosgene such as trichloromethyl chloroformate (diphosgene), bis (trichloromethyl) carbonate (triphosgene) or N, N' -carbonyldiiimi It can be synthesized by treatment with dozol (CDI). Isocyanates can also be derived from anhydrides by rearrangement reactions of heterocyclic carboxylic acid derivatives such as esters, acid halides or Curtius types. Thus, the reaction of the acid derivative 16 with an azide source followed by a rearrangement reaction provides the isocyanate. Corresponding carboxylic acids 17 may also undergo a Curtis type rearrangement reaction using diphenylphosphoryl azide (DPPA) or similar agent.

Selected Method of Asymmetric Urea Formation

Finally, urea will be further manipulated in a manner familiar to those skilled in the art.
