Obeticholic Acid (INT747; 6-ECDCA; 6-Ethylchenodeoxycholic acid; trade name Ocaliva), a novel derivative of cholic acid, is a potent, orally bioactive and selective agonist of farnesoid X receptor (FXR) with EC50 of 99 nM, and has anticholeretic and anti-inflammatory activities. It is a semi-synthetic analog of bile acid which has the chemical structure 6α-ethyl-chenodeoxycholic acid. Obeticholic Acid was approved in 2016 for use as a drug to treat primary biliary cholangitis, and is undergoing development for several other liver diseases and related disorders. It displays anticholeretic activity in a 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.

ln Vitro |
In rat hepatocytes, obeticholic acid (INT-747) elevates the expression of FXR-regulated genes[1]. Liver JNK-1 and JNK-2 expression is decreased by obeticholic acid (INT-747)[2]. In every examined strain, obeticholic acid (INT-747) at 256 μg/mL completely inhibits bacterial growth. After INT-747 is added to an intestinal epithelium of Caco-2 cells that has been exposed to IFN-γ, intestinal permeability is not changed[3].

ln Vivo |
The cholestasis caused by E217α was totally reversed by obeticholic acid (INT-747) (10 mg/kg/day). By boosting the relative abundance of β -MCA, TCDCA, and TDCA, the administration of obeticholic acid (INT-747) partially reverses the impairment in total bile acid secretion caused by E217α[1]. In the mice, obeticholic acid (INT-747)7 (10 mg/kg) and HS exacerbate lung congestion. In animals administered HS, INT-747 does not improve renal pathology[2]. In BDL rats, obeticholic acid (INT-747) (5 mg/kg) considerably improves survival. BDL rats treated with obeticholic acid (INT-747) show a substantial increase in the expression of pore-closing claudin-1 only in the ileum. ZO-1 is markedly up-regulated in the ileum in BDL rats treated with INT-747[3].

Cell Assay |
The exposure of rat hepatocytes to 1 microM 6-ECDCA caused a 3- to 5-fold induction of small heterodimer partner (Shp) and bile salt export pump (bsep) mRNA and 70 to 80% reduction of cholesterol 7alpha-hydroxylase (cyp7a1), oxysterol 12beta-hydroxylase (cyp8b1), and Na(+)/taurocholate cotransporting peptide (ntcp) [2].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
