产品介绍

熊去氧胆酸,主要成分是3a,7β- 二羟基-5β- 胆甾烷-24-酸,为有机化合物,无臭,味苦。本品在乙醇中易溶,在氯仿中不溶;在冰醋酸中易溶,在氢氧化钠试液中溶解。医学上用于增加胆汁酸分泌,并使胆汁成分改变,降低胆汁中胆固醇及胆固醇脂,有利于胆结石中的胆固醇逐渐溶解。阴离子去垢剂,用于生化研究。

Ursodeoxycholic acid is a bile acid with significant colon chemopreventive activity.
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.

生物活性评价 We have been unable to find publicly available affinity data for this drug at its proposed molecular target to substantiate its MMOA, and have therefore not tagged a primary drug target.
评价 Ursodeoxycholic acid (UDCA) acts as an antagonist of the bile acid receptor farnesoid X receptor (FXR) .

SARS-CoV-2 and COVID-19: ACE2's presence on host cells confers susceptibility to SARS-CoV-2 infection. UDCA attenuates bile acid-induced, FXR-mediated upregulation of ACE2 expression in vitro and in vivo . For this effect, UDCA has been proposed as a repurposing drug with antiviral potential against SARS-CoV-2. It is hypothesised that UDCA would reduce SARS-CoV-2 infection potential by lowering the number of ACE2 binding sites on relevant tissues. In support of this theory, a correlation between UDCA treatment for liver conditions and a lower risk of developing severe COVID-19 has been identified,

Ursodeoxycholic acid is found in large quantities in bear bile and this results in the practice of 'farming' bears for bile extraction, in some countries.
