Summary

Antipain is a natural peptide aldehyde produced by Streptomyces species, used exclusively as a biochemical research tool. It inhibits multiple serine and cysteine proteases and is widely employed in protease inhibitor cocktails for cell lysate preparation and protein purification. It has no approved therapeutic use.

Mechanism of Action

Competitive inhibitor of serine and cysteine proteases, including trypsin, papain, cathepsin B, and plasmin; contains an arginal warhead (aldehyde group) that reversibly forms a covalent hemiacetal with the active site serine or cysteine residue of target proteases
