Product Description: N-alpha-Tosyl-Lys chloromethyl ketone hydrochloride (TLCK hydrochloride) is an irreversible inhibitor for serine protease, which inhibits trypsin and trypsin-like protease by alkylating histidine residues in their active site. N-alpha-Tosyl-Lys chloromethyl ketone hydrochloride inhibits caspase-3, caspase-6 and caspase-7, with IC50s of 12.0, 54.5 and 19.3 μM, respectively. N-alpha-Tosyl-Lys chloromethyl ketone hydrochloride induces apoptosis in cell HL-60, and inhibits the decrease in mitochondrial transmembrane potential during apoptosis[1].
Applications: Cancer-Kinase/protease
Formula: C14H22Cl2N2O3S
