Cas No.:1553-56-6
Sample solution is provided at 25 µL, 10mM.
Dehydrolithocholic acid is a major metabolite of lithocholic acid .[1] It is formed from LCA by the cytochrome P450 (CYP) isoform CYP3A4. Dehydrolithocholic acid is an agonist of G protein-coupled bile acid activated receptor 1 (GP-BAR1/TGR5; EC50 = 0.27 μM), vitamin D receptor (VDR; EC50 = 3 μM), and farnesoid X receptor (FXR) in cell-based reporter assays.[2],[3] It also binds to the human pregnane X receptor (PXR; IC50 = 15 μM) and activates mouse and human PXRs in cell-based reporter assays when used at a concentration of 100 μM.[4] Dehydrolithocholic acid binds to retinoic acid receptor-related orphan receptor γt (RORγt; Kd = 1.13 μM for the recombinant human ligand-binding domain) and decreases its activity in a cell-based reporter assay when used at a concentration of 10 μM.[5] It inhibits the differentiation of T helper cells that express IL-17a (TH17 cells) when used at a concentration of 20 μM.

DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
