General description
A cell-permeable inhibitor of caspase-3. The C-terminal DEVD-CHO sequence of this peptide is a highly specific, potent, and reversible inhibitor of caspase-3 (Ki<1 nM) that has also been shown to strongly inhibit PARP cleavage in cultured human osteosarcoma cell extracts (IC50 = 200 pM). The N-terminal sequence (residues 1-16) corresponds to the hydrophobic region (h-region) of the signal peptide of Kaposi fibroblast growth factor (K-FGF) and confers cell-permeability to the peptide.
