Cat. No. 0448
Chemical Name: N-Benzyloxycarbonyl-L-leucylnorleuc
Biological ActivityPotent, cell-permeable inhibitor of the Ca2+-dependent protease, calpain. Prevents collagen- and thrombin-induced platelet aggregation, probably by blocking calpain induced phospholipase C and thromboxane synthase activation. Potent cathepsin L inhibitor. Recently shown to preferentially inhibit a subset of protein-tyrosine phosphatases.
