Obeticholic Acid

Obeticholic Acid (INT747; 6-ECDCA) is a novel derivative of cholic acid which acts as a potent and selective FXR agonist displaying anticholeretic activity in an in vivo rat model of cholestasis. It inhibits vascular smooth muscle cell inflammation and migration as well as promotes adipocyte differentiation and regulates adipose cell function in vivo.

How to use

In Vitro:

Obeticholic acid (INT-747) increases the expression of FXR-regulated genes in rat hepatocytes. Obeticholic acid (INT-747) reduces expression of liver JNK-1 and JNK-2. Obeticholic acid (INT-747) (256 μg/mL) shows complete inhibition of bacterial growth in all strains tested. Intestinal permeability remains unaffected after INT-747-addition to an IFN-γ-exposed intestinal epithelium of Caco-2 cells.

In Vivo:

Obeticholic acid (INT-747) (10 mg/kg/day) completely reverted cholestasis induced by E217α. Administration of Obeticholic acid (INT-747) partially prevents the impairment in total bile acid output caused by E217α by increasing the relative abundance of β-MCA and TCDCA and TDCA. Obeticholic acid (INT-747)7 (10 mg/kg) and HS increases the pulmonary congestion in the animals. INT-747 does not improve renal pathology in the HS-fed animals. Obeticholic acid (INT-747) (5 mg/kg) significantly increases survival in BDL rats. Obeticholic acid (INT-747)-treated BDL rats exhibits a significant selective ileal increase in expression of pore-closing claudin-1. Ileal expression of ZO-1 is significantly up-regulated in INT-747-treated BDL rats.
