| ANTIPAIN, DIHYDROCHLORIDE Usage And Synthesis |
| Description | Antipain is a protease inhibitor originally isolated from actinomycetes. 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). In vivo, antipain (25-100 mg/kg) suppresses urethan-induced formation of cleft palates and cleft lips in mice. | | Uses | Concentrations for 50% inhibition (μg/ml): papain, 0.16trypsin, 0.26cathepsin A, 1.19cathepsin B, 0.59cathepsin D, 125plasmin, >93chymotrypsin and pepsin, >250It also has been reported to inhibit calpain I, (porcine) with Ki = 1.4 μM | | Uses | Antipain inhibits trypsin, papain, and catherpsins A and B (a reversible inhibitor of cysteine and serine proteases). It is used to evaluate the role of proteases in cell transformations. It is used to help identify new proteases. | | General Description | Antipain is a protease inhibitor isolated from actinomycetes. It inhibits thrombokinase and blood coagulation. | | Biochem/physiol Actions | Reversible inhibitor of serine/cysteine proteases and some 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. | | References | 1) Umezawa?et al.?(1976),?Structures and activities of protease inhibitors of microbial origin; Method Enzymol.,?45?678
