Antipain-dihydrochloride

Description

General Description

Antipain, Dihydrochloride, produced by actinomycetes, is a reversible inhibitor of serine/cysteine proteases (cathepsin A, B, and D as well as papain) and some trypsin and 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. Antipain acts by forming a hemiacetal adduct between the aldehyde group of the inhibitor and the active serine of the proteinase. Effective at concentrations range from 1 to 100 μM.
