Microbial Product (Hydrochloride Form)

Inhibitor for Trypsin, Papain, and Cathepsin A/B

Antipain [37682-72-7], is a high purified microbial product isolated from culture media of actinomycetes. This microbial peptide aldehyde is a specific inhibitor for all trypsin like proteases. It acts like leupeptin or elastatinal, but seems to be more specific. Antipain is often used as essential component in typical protease inhibitor cocktails.
