A6191 Antipain dihydrochloride from microbial source protease inhibitor Reversible inhibitor of serine/cysteine proteases and some trypsin-like serine proteases. Its action resembles leupeptin; however, its plasmin inhibition is less and its cathepsin A inhibition is more than that observed with leupeptin. Chronic administration of antipain can reduce the frequency of chemically induced transformation in BALB/c-/3T3 cells.
E0514 E-64c Calpain Inhibitor Cysteine protease inhibitor; membrane-impermeable calpain inhibitor. Significantly reduces calpain-mediated depletion of microtubule-associated protein (MAP2) in an animal model of an ischemic brain.
E8640 E-64d protease inhibitor  
L2023 Leupeptin trifluoroacetate salt ≥90% (HPLC), microbial Inhibitor of serine and cysteine proteases. Inhibits plasmin, trypsin, papain, calpain, and cathepsin B. Does not inhibit pepsin, cathepsins A and D, thrombin, or α-chymotrypsin. Effective concentration 10-100 μM. There have been numerous studies using leupeptin to protect against hearing loss caused by acoustic overstimulation or the ototoxic antibiotic gentamicin. (Loss of cochlear hair cells is believed to be mediated by calpain.)
