Antipain is a protease inhibitor originally isolated from actinomycetes.[1] It inhibits thrombokinase, plasmin, trypsin, and papain in vitro (IC50s = 20, 93, 0.26, and 0.16 μg/ml, respectively). Antipain (6-600 μg/ml) inhibits the morphological transformation of and increases frequency of chromosomal aberrations in Syrian hamster embryo cells induced by N-methyl-N'-nitro-N-nitroso-guanidine (MNNG).[2] In vivo, antipain (25-100 mg/kg) suppresses urethan-induced formation of cleft palates and cleft lips in mice.[3]
