This invention provides caspase inhibitors having the formula: (I) wherein Ring A is an optionally substituted piperidine, tetrahydroquinoline or tetrahydroisoquinoline ring; R<1> is hydrogen, CHN2, R, or -CH2Y; R is an optionally substituted group selected from an aliphatic group, an aryl group, an aralkyl group, a heterocyclic group, or an heterocyclylalkyl group; Y is an electronegative leaving group; R<2> is CO2H, CH2CO2H, or esters, amides or isosteres thereof; Ar is an optionally substituted aryl group; and R<3> is hydrogen, an optionally substituted C1-6 alkyl, F2, CN, aryl or R<3> is attached to Ar to form an unsaturated or partially saturated five or six membered fused ring having 0-2 heteroatoms. The compounds are useful for treating caspase-mediated diseases in mammals. |
