Sodium taurodeoxycholate hydrate 是一种胆汁酸，是由肝脏中的胆固醇合成的两亲性表面活性剂分子。 除TGR5通路外，Sodium taurodeoxycholate hydrate 还激活S1PR2通路。
| 生物活性 | Sodium taurodeoxycholate hydrate, a bile acid, is an amphiphilic surfactant molecule synthesized fromcholesterolin the liver. Sodium taurodeoxycholate hydrate activates theS1PR2pathway in addition to theTGR5pathway[1]. |

体外研究
(In Vitro) | The median plasma concentration of Taurodeoxycholate is 33.9 nM in healthy individuals[1].
Taurodeoxycholate inhibits the binding of N-3H-methylscopolamine to the M3 muscarinic receptor of acetylcholine with an IC50of 170 μM[1].
Taurodeoxycholate (0.05-1.00 mM; 1-6 days) stimulates intestinal epithelial cell proliferation[2].
Taurodeoxycholate (0.05-1.00 mM; 24 h) induces a significant increase in S-phase concentration and a significant decrease in G1-phase concentration of the cell cycle, increases c-myc protein and mRNA expression in IEC-6 cells[2].
Cell Proliferation Assay[2] | Cell Line: | IEC-6 and caco-2 cells | | Concentration: | 0, 0.05, 0.50, and 1.00 mM | | Incubation Time: | 1, 2, 4 and 6 days | | Result: | Significantly stimulated intestinal epithelial cell proliferation in a dose-dependent manner. |
Cell Cycle Analysis[2] | Cell Line: | IEC-6 cells | | Concentration: | 0, 0.05, 0.50, and 1.00 mM | | Incubation Time: | 24 h | | Result: | Significantly increased cells in S phase and decreased cells in G1-phase. |
Western Blot Analysis[2] | Cell Line: | IEC-6 cells | | Concentration: | 0.5 mM | | Incubation Time: | 1 and 6 days | | Result: | Significantly increased c-myc protein expression. |

体内研究
(In Vivo) | Taurodeoxycholate (0.5 mg/kg; i.v.; once) confers protection to C57BL/6N mice with sepsis, but does not protect TGR5 KO mice under sepsis[1].
| Animal Model: | C57BL/6N mice,Lipopolysaccharides(HY-D1056) injection model of sepsis[1] | | Dosage: | 0.5 mg/kg | | Administration: | Intravenous injection, 30 min or 24 h after LPS injection | | Result: | Improved the survival rate of mice with sepsis. Decreased liver and kidney damage in septic mice. Ameliorated systemic inflammation and normalized blood pressure in septic mice. |
