Description
Analysis Note |
Leupeptin gives multiple peaks on HPLC due to equilibria among three forms in solution. Purity determined using three main peaks. Majority of contaminating peptide is racemized leupeptin. |
Biochem/physiol Actions |
Inhibitor of serine and cysteine proteases. Inhibits plasmin, trypsin, papain and cathepsin B. No inhibition found with pepsin, cathepsins A and D, thrombin, or α-chymotrypsin. Effective concentration 10-100 μM. |
