Cysteine protease

Acetyl-Calpastatin (184-210) (human), selective calpain inhibitor. Strongly inhibits calpain I (Ki = 0.2 nM) and II but does not inhibit papain, trypsin and cathepsin L (Ki = 6 uM). Increases secretion of amyoid β-protein (Aβ) 42, Aβ40 and Aβ42 ratio.

LY3000328 is a Cathepsin S inhibitor with excellent in vitro potency and selectivity against other cysteine proteases.

Cysteine Protease inhibitor is an inhibitor of cysteine protease.
