Beschreibung

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).
