Product Information

• Name: Ursodeoxycholic acid methyl ester
• Synonyms: (3a,5b,7b)-3,7-Dihydroxycholan-24-oic acid
• Brand: Biosynth
• Description: Ursodeoxycholic acid methyl ester is a bile acid that is produced from ursodeoxycholic acid. It is used as a drug to dissolve gallstones and reduce the risk of recurrent gallstones in patients who have had a cholecystectomy. Ursodeoxycholic acid methyl ester also reduces cholesterol levels by preventing its reabsorption in the small intestine and enhancing its excretion in the bile. This agent has been shown to modulate cell proliferation and differentiation, especially in cerebral tissue and muscle cells. Ursodeoxycholic acid methyl ester can be synthesized from ursodeoxycholic acid by saponification with base followed by methylation with methanol. The synthesis of this agent involves an elimination reaction between c1-c3 alcohols, which leads to impurities such as formaldehyde, acetone, glycerol, acetic acid, and butyric acid.
