Obeticholic Acid (6alpha-ethyl-chenodeoxycholic acid, 6-ECDCA, INT-747) is a potent and selective agonist of FXR with EC50 value of 99 nM [1].
The farnesoid X receptor (FXR) is a nuclear bile acid receptor involved in bile acid homeostasis, liver fibrosis, hepatic and intestinal inflammation and cardiovascular disease [2].
Obeticholic Acid is a potent and selective FXR agonist with anticholeretic activity [1]. Obeticholic Acid is a semisynthetic bile acid derivative and potent FXR ligand. In estrogen-induced cholestasis rats, 6-ECDCA protected against cholestasis induced by 17α-ethynylestradiol (E217α) [2]. In cirrhotic portal hypertension (PHT) rat models, INT-747 (30 mg/kg) reactivated the FXR downstream signaling pathway and reduced portal pressure by lowering total intrahepatic vascular resistance (IHVR) without deleterious systemic hypotension. This effect was associated with an increased eNOS activity [3]. In the Dahl rat model of salt-sensitive hypertension and insulin-resistance (IR), high salt (HS) diet significantly increased systemic blood pressure and downregulated tissue DDAH expression. INT-747 enhanced insulin sensitivity and inhibited the decrease of DDAH expression [4].
