Ursocholic acid
Based on 2 publication(s) in Google Scholar
Ursocholic acid, a bile acid present in mammalian bile, is converted to deoxycholic acid (UDC) by the mouse intestinal flora. Ursocholic acid acts as a gallstone dissolving agent in the liver through anti-apoptosis, anti-inflammatory, immunomodulatory, bile regulation, and coordinated changes in mitochondrial integrity and cell signaling, Ursocholic acid also has favorable effects on bones in patients with chronic cholestasis.

Human Endogenous Metabolite |
Ursocholic acid (1 μM, 10 μM, 100 μM and 1 mM, 24-72 h) has no deleterious effect on osteoblast survival at a lower concentration (100 μM), increases osteoblast differentiation treated with LCA (10 μM), and neutralizes the deleterious effects of bilirubin (50 μM)[5]. Ursocholic acid (1 μM, 10 μM and 100 μM, 7-28 days) increases osteoblast mineralization by 35% and 9% at days 21 and 28 at a dose of 100 μM[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
