Leupeptin
2-(2-Acetamido-4-methylvaleramido)-N-(1-formyl-4-guanidinobutyl)-4-methylvaleramide
A tripeptide composed of N-acetylleucyl, leucyl and argininal residues joined in sequenceby peptide linkages. It is an inhibitor of the calpains, a family of calcium-activated proteases which promote cell death.
