3-氧代-5β-胆固醇酸(脱氢胆酸)是一种胆汁酸代谢产物,能够通过直接与关键转录因子RORγt结合(Kd=1.13 μM),抑制TH17细胞分化。
体外研究使用3-氧代-5β-胆固醇酸处理显著减少了RORγt报告基因的活性。这些数据表明,3-氧代-5β-胆固醇酸可能通过物理结合与RORγt,并抑制其转录活性来抑制TH17细胞分化。
体内研究0.3% (w/w) 的3-氧代-5β-胆固醇酸(脱氢胆酸)灌胃给药一周显著减少了回肠中TH17细胞的百分比。

For the first time, hybrid molecules were synthesized on the basis of lithocholic and (5Z,9Z)-1,14-tetradeca-5,9-dienedicarboxylic acids, obtained in two stages using the homo-cyclomagnesiation reaction of 2-(hepta-5,6-diene-1-yloxy)tetrahydro-2H-pyran at the key stage. The resulting hybrid molecules containing 5Z,9Z-dienoic acids are of interest as novel synthetic biologically active precursors to create modern drugs for the treatment of human oncological diseases. The synthesized hybrid molecules were found to exhibit extremely high in vitro inhibitory activity against human topoisomerase I, which is 2–4 times higher than that of camptothecin, a known topoisomerase I inhibitor. Using flow cytometry and fluorescence microscopy, it was first shown that these new molecules are efficient apoptosis inducers in HeLa, U937, Jurkat, K562, and Hek293 cell cultures. In addition, the results of investigations into the effect of the synthesized acids on mitochondria and studies of possible DNA damage in Jurkat tumor cells are also presented.
