IMPROVED MATRIX METALLOPROTEASE INHIBITORS

摘要

Compounds of the formulas (1) (2) wherein each R1 is independently H or alkyl (1-8C) and R2 is alkyl (1-8C) or wherein the proximal R1 and R2 taken together are -(CH2)p- wherein p=3-5; R3 is H or alkyl (1-4C); R4 is fused or conjugated unsubstituted or substituted bicycloaryl methylene; n is 0, 1 or 2; m is 0 or 1; and X is OR5 or NHR5, wherein R5 is H or substituted or unsubstituted alkyl (1-12C), aryl (6-12C), aryl alkyl (6-16C); or X is an amino acid residue or amide thereof; or X is the residue of a cyclic amine or heterocyclic amine; wherein R6 is H or lower alkyl (1-4C) and R7 is H, lower alkyl (1-4C) or an acyl group, and wherein -CONR3- is optionally in modified isosteric form are useful for treating conditions which are characterized by unwanted matrix metalloprotease activities.
