Uses

Used in Pharmaceutical Industry:
(E/Z)-3α-hydroxy-6-ethylidene-7-keto-5β-cholan-24-oic acid Methyl ester is used as a reactant in the preparation of dual agonists of nuclear and membrane bile acid receptors. This application is significant because bile acid receptors play crucial roles in various physiological processes, including the regulation of cholesterol and glucose homeostasis, as well as the modulation of inflammation and energy metabolism. By acting as dual agonists, these compounds can potentially offer therapeutic benefits in treating a range of conditions, such as metabolic disorders, liver diseases, and inflammatory conditions.
