Description:
Ursodeoxycholic acid (UDCS) is a cell protectant used extensively to mitigate hepatic and biliary diseases. Ursodeoxycholic acid may be used to study its specific activities that range from reduction of cholesterol absorpition, cholesterol gallstone dissolution to suppression of immune response.IC50: M1-family aminopeptidase: IC50 = 2.6 µM (Plasmodium falciparum 3D7); NTCP: IC50 = 3.6 µM (human); HCT-116: IC50 = >50 µM (human); GBM: IC50 = >50 µM (human) Asbt: Ki= 75 µM (human)
