General description
A tetrapeptidyl aldehyde that acts as a potent, reversible and active site binding inhibitor of caspases-3 and -7 (IC50 = 3.2 nM and 22.6 nM, respectively) and displays ~100-fold greater selectivity over caspases-8 and -9 (IC50 = 577.6 nM and 364.7 nM, respectively). Offers protection against Camptothecin (Cat. No. 208925), and anti-Fas-mediated apoptosis in Jurkat T cells.

Note: aldehyde-based inhibitors are less cell-permeable than FMK-based inhibitors, so higher concentrations may be required for cell-based inhibition studies (e.g. 100 µM).

Caspase-9 is traditionally considered the initiator caspase of the intrinsic apoptotic pathway. In the past decade, however, other functions beyond initiation/execution of cell death have been described including cell type-dependent regulation of proliferation, differentiation/maturation, mitochondrial, and endosomal/lysosomal homeostasis.
