Medchemexpress/INT-747(Synonyms: Obeticholic acid; 6-ECDCA; 6-Ethylchenodeoxycholic acid)/HY-12222/500mg
| Description |
INT-747 is a potent and selective FXR agonist (EC50=99 nM) endowed with anticholestatic activity. |

| IC50 & Target |
EC50: 99 nM (FXR) |
| In Vitro |
6-ECDCA increases the expression of FXR-regulated genes in rat hepatocytes[1]. INT-747 reduces expression of liver JNK-1 and JNK-2[2]. 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[3]. |
| In Vivo |
6-ECDCA (10 mg/kg/day) completely reverted cholestasis induced by E217α. Administration of 6-ECDCA partially prevents the impairment in total bile acid output caused by E217α by increasing the relative abundance of β-MCA and TCDCA and TDCA[1]. INT-747 (10 mg/kg) and HS increases the pulmonary congestion in the animals.INT-747 does not improve renal pathology in the HS-fed animals[2]. INT-747 (5 mg/kg) significantly increases survival in BDL rats. 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[3]. |

| Animal Administration
[2] |
INT-747 is formulated in 1% methylcellulose in distilled water. Initially, all animals (at 6-weeks age) are placed on a standard rodent diet for a week. Baseline blood and urine samples are collected and basal blood pressure (BP) is measured prior to grouping the animals. Subsequently, the animals are randomized into low (LS; n=9) or high salt (HS) diet groups. Hypertension is induced in the HS group by daily high-salt diet feeding and the group is subdivided to receive one of two doses of INT-747: low dose (10 mg/kg/day; n=15) or high dose (30 mg/kg/day; n=15) in 1% methylcellulose; or vehicle (1% methylcellulose in distilled water; n=15) orally everyday for 6 weeks. In parallel, the LS group also receive 1% methylcellulose. BP is measured weekly for the duration of the study as described below. MCE has not independently confirmed the accuracy of these methods. They are for reference only. |
