牛磺鹅去氧胆酸钠是动物胆汁酸的主要生物活性物质之一。牛磺鹅脱氧胆酸钠可诱导细胞凋亡，并显示出明显的抗炎和免疫调节特性。它可以增加葡萄糖诱导的胰岛素分泌并刺激α2细胞的电活动并提高胞质Ca(2+)浓度([Ca(2+)](c))。

Sodium taurochenodeoxycholate is one of the main bioactive substances of animals' bile acid.?Sodium taurochenodeoxycholate induces apoptosis and shows obvious anti-inflammatory and immune regulation properties. It can increase glucose-induced insulin secretion and stimulate the electrical activity of α2-cells and enhance cytosolic Ca(2+) concentration ([Ca(2+)](c)).Experiments were performed with islets from wild-type, farnesoid X receptor (FXR) knockout (KO), and β-cell ATP-dependent K(+) (K(ATP)) channel gene SUR1 (ABCC8) KO mice, respectively. Sodium taurochenodeoxycholate (TCDC) increased glucose-induced insulin secretion. This effect was mimicked by the FXR agonist GW4064 and suppressed by the FXR antagonist guggulsterone. TCDC and GW4064 stimulated the electrical activity of β-cells and enhanced cytosolic Ca(2+) concentration ([Ca(2+)](c)). These effects were blunted by guggulsterone. Sodium ursodeoxycholate, which has a much lower affinity to FXR than TCDC, had no effect on [Ca(2+)](c) and insulin secretion. FXR activation by TCDC is suggested to inhibit K(ATP) current. The decline in K(ATP) channel activity by TCDC was only observed in β-cells with intact metabolism and was reversed by guggulsterone. TCDC did not alter insulin secretion in islets of SUR1-KO or FXR-KO mice. TCDC did not change islet cell apoptosis.

Taurochenodeoxycholic acid (12-Deoxycholyltaurine) sodium dramatically improves the apoptosis rate of NR8383 cells in a concentration-dependent manner. In the meantime, Taurochenodeoxycholic acid sodium significantly augments PKC mRNA levels, activities and increases JNK, caspase-3 and caspase-8 mRNA expression levels, activities.

Taurochenodeoxycholic acid (12-Deoxycholyltaurine; TCDCA; 0.05, 0.1g/kg) sodium decreases the pulmonary coefficient in the model mice and reduces the pathological damages on their lungs; it can decrease the expression levels of TNF-α and TIMP-2 in pulmonary tissues in the pulmonary fibrosis mice and has no significant effects on MMP2. Taurochenodeoxycholic acid sodium significantly normalizes the clinical inflammatory parameters, prevented indomethacin-induced increases in the biliary contents of secondary bile acids and hydrophobicity index, and tended to attenuate the intestinal inflammation.Taurochenodeoxycholic acid sodium significantly suppresses paw swelling and polyarthritis index, increases the loss body weight and index of thymus and spleen, and amends radiologic changes in AA rats. The overproduction and mRNA expression of TNF-α, IL-1β and IL-6 are remarkably suppressed in serum and synovium tissue of all TCDCA-treated rats.
