A reversible inhibitor of cysteine, serine, and threonine proteases; inhibits cathepsin B (Ki = 6 nM), calpain (Ki = 10 nM), trypsin (Ki = 35 nM), plasmin (Ki = 3.4 μM), and kallikrein (Ki = 19 μM), and has no effect against chymotrypsin, elastase, renin, or pepsin.

CAS No.: 103476-89-7

Leupeptin is a modified tripeptide reversible protease inhibitor of trypsin-like proteases and some cysteine proteases including endoproteinase Lys-C, kallikrein, papain, thrombin, cathepsin B, cathepsins H and L, trypsin, calpain, trypsin8 and plasmin. Effective concentration is typically 10-100…

Potent, competitive and reversible cysteine, serine and threonine protease inhibitor. Inhibits calpain, kallikrein, trypsin, plasmin, papain and cathepsin B. Does not inhibit pepsin, elastase, renin, cathepsins A and D, thrombin or alpha-chymotrypsin. Used to protect against hearing loss caused by…
