A compound of formula
wherein
R1 is hydrogen, or C1-4 alkyl;
R2 is C1-10 alkyl, optionally substituted arylC1-4alkyl, optionally substituted heteroaryl C1-4 alkyl optionally substituted C3-7 cycloalkyl, or R1 and R2 together with the nitrogen to which they are attached from a 3 to 10 membered ring which optionally contains an aditional heteroatom selected from oxygen, nitrogen or sulfur,
R3 and R4 are C1-6alkyl, hydrogen, nitro, or halogen and
R5 is C1-6alkyl, hydrogen, arylalkyl or heteroarylalkyl.
The present invention is to the novel compounds of Formula (I), their pharmaceutical compositions, and to the novel inhibition of Caspases for use in the treatment of apoptosis, and disease states caused by excessive or inappropriate cell death.
