General description

A potent, cell-permeable, and specific, reversible inhibitor of caspase-3 (K_i = 60 nM) and caspase-7 (K_i = 170 nM).

A potent, reversible, isatin sulfonamide-based inhibitor of caspase-3 (K_I(app) = 60 nM) and caspase-7 (K_I(app) = 170 nM). Inhibits caspase-9 to a lesser extent (K_i(app) = 3.1 µM). Has only a trivial effect (K_i(app) >25 mM) on the activities of caspase-1, caspase-2, caspase-4, caspase-6, and caspase-8. Reported to inhibit apoptosis in camptothecin treated Jurkat cells (IC₅₀ ~50 µM). Also reported to inhibit apoptosis in chondrocytes (44% inhibition at 10 µM and 98% inhibition at 50 µM). Selectivity for caspases 3 and 7 involves unique hydrophobic residues in the S2 pocket surrounding the catalytic cysteine residue.
