Ursodeoxycholic acid (Synonyms: 熊去氧胆酸; Ursodeoxycholate; Ursodiol; UDCA) 纯度: ≥98.0%

Ursodeoxycholic acid (Ursodeoxycholate) 是由肠道细菌转化 (cheno)脱氧胆酸而产生的一种次级胆汁酸，是肠道屏障完整性的关键调节因子，对脂质代谢至关重要。Ursodeoxycholic acid 作为信号分子，通过与胆汁酸激活的受体相互作用发挥作用，包括G蛋白偶联的胆汁酸受体5 (TGR5，GPCR19) 和法尼酯X受体 (FXR)。Ursodeoxycholic acid 可用于多种肝脏和胃肠道疾病的研究。具有口服活性。

生物活性

Ursodeoxycholic acid (Ursodeoxycholate) is a secondary bile acid issued from the transformation of (cheno)deoxycholic acid by intestinal bacteria, acting as a key regulator of the intestinal barrier integrity and essential for lipid metabolism. Ursodeoxycholic acid acts as signaling molecule, exerting its effects by interacting with bile acid activated receptors, including G-protein coupled bile acid receptor 5 (TGR5, GPCR19) and the farnesoid X receptor (FXR). Ursodeoxycholic acid can be used for the research of a variety of hepatic and gastrointestinal diseases. Orally active[1][2].

体内研究
(In Vivo)

Ursodeoxycholic acid (50, 150, and 450 mg/kg; p.o.; daily for 21 days) results in weight loss in C57BL/6J wildtype mice[1].

上海金畔生物科技有限公司 has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: 5 week old C57BL/6J WT mice (male and female)[1]
Dosage: 50, 150, and 450 mg/kg dissolved in corn oil
Administration: Oral gavage; daily for 21 days
Result: Mice in the 50 and 450 mg/kg groups sustained significant weight loss within a week. At 50 mg/kg, this weight loss persisted over the course of the experiment. At 450 mg/kg, initially weight loss was noted during the first and third week of ursodiol administration. At 150 mg/kg, it did not have significantly different weights compared to the untreated mice.
