常見問題列表
生物活性
3-Oxo-5β-cholanoic acid (Dehydrolithocholic acid)，膽汁酸代謝產物，通過直接與關鍵轉錄因子RORγt (Kd=1.13 μM) 結合抑制 TH17 細胞分化。體外研究
Treatment with 3-Oxo-5β-cholanoic acid significantly reduced the activity of the RORγt reporter. These data suggest that 3-Oxo-5β-cholanoic acid probably inhibits TH17 cell differentiation by physically interacting with RORγt, and inhibiting its transcriptional activity.
