Human ADAM-10 inhibitors
View Patent ↗The present invention provides compounds useful for inhibiting the ADAM-10 protein, with selectivity versus MMP-1. Such compounds are useful in the in vitro study of the role of ADAM-10 (and its inhibition) in biological processes. The present invention also comprises pharmaceutical compositions comprising one or more ADAM-10 inhibitors according to the invention in combination with a pharmaceutically acceptable carrier. Such compositions are useful for the treatment of cancer, arthritis, and diseases related to angiogenesis. Correspondingly, the invention also comprises methods of treating forms of cancer, arthritis, and diseases related to angiogenesis in which ADAM-10 plays a critical role.
1. A method of making a bis-aryl ether sulfonyl halide according to formula VII:
wherein X is a halide; and W 1 and W 2 are each independently an optionally substituted aryl, the method comprising: (a) combining a metal-aryloxide salt of a corresponding hydroxide-substituted aryl compound with a fluoro-substituted nitro aryl compound to make a bis-aryl ether nitro-aromatic compound; (b) reducing a nitro group of the bis-aryl ether nitro-aromatic compound to produce a corresponding aniline derivative; and (c) converting the corresponding aniline derivative to the bis-aryl ether sulfonyl halide.
2. The method of claim 1 , wherein (a)-(c) are performed in the order described.
3. The method of claim 2 , wherein the metal-aryloxide salt is combined with the fluoro-substituted nitro aryl in an organic solvent.
4. The method of claim 3 , wherein the organic solvent comprises at least one of DMF and acetonitrile.
5. The method of claim 4 , wherein the metal-aryloxide salt comprises at least one of a cesium salt and a potassium salt.
6. The method of claim 5 , wherein the corresponding aniline derivative is converted to the bis-aryl ether sulfonyl halide via a diazonium intermediate of said corresponding aniline derivative.
7. The method of claim 6 , wherein the fluoro-substituted nitro aryl compound is 3,4,5-trifluornitrobenzene.
8. The method of claim 7 , wherein the metal-aryloxide salt is a cesium salt.
9. The method of claim 8 , wherein the corresponding hydroxide-substituted aryl compound is 4-chlorophenol.
10. The method of claim 9 , wherein the bis-aryl ether sulfonyl halide is 4-(4-chlorophenoxy)-3,5-difluorophenylsulfonyl chloride.
