Background

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].

运输条件试用装:蓝冰运输。 其他可选规格:常温运输或根据您的要求用蓝冰运输。
一般建议为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。

试验操作

细胞实验 [1]:

细胞系

大鼠肝细胞

制备方法

溶解度有限。若配制更高浓度的溶液,一般步骤如下:请将试管置于37℃加热10分钟和/或将其置于超声波浴中震荡一段时间。原液于-20℃可放置数月。

反应条件

24 h

实验结果

在大鼠肝细胞中,Obeticholic acid反式激活FXR并调节FXR调节基因,导致Shp和bsep mRNA表达增加3至5倍,FXR配体处理后,cyp7a1、cyp8b1和ntcp的mRNA表达降低50至70%。

动物实验 [2]:

动物模型

雄性Wistar大鼠,重量200-250 g

给药剂量

30 mg/kg

制备方法

溶于0.75-1.0 mL新鲜制备的甲基纤维素(1%)

实验结果

Obeticholic acid可以重新激活下游FXR信号通路并减少硫代乙酰胺(TAA)和胆管结扎(BDL)模型中的PP,而不影响全身血液动力学。它还恢复实验性肝硬化中内皮功能,减少总IHVR。

注意事项

请于室内测试所有化合物的溶解度。虽然化合物的实际溶解度可能与其理论值略有不同,但仍处于实验系统误差的允许范围内。
