37682-72-7 Usage
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
Different sources of media describe the Uses of 37682-72-7 differently. You can refer to the following data:
1. 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
2. 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.

Check Digit Verification of cas no
The CAS Registry Mumber 37682-72-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,6,8 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 37682-72:
(7*3)+(6*7)+(5*6)+(4*8)+(3*2)+(2*7)+(1*2)=147
147 % 10 = 7
So 37682-72-7 is a valid CAS Registry Number.
