Działania biochem./fizjol.

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.)

Komentarz do analizy

Leupeptin gives multiple peaks on HPLC because of the formation of tautomeric isomers in solution. Majority of contaminating peptide is racemized leupeptin.
