| 产品描述 | Lithocholic acid (3α-Hydroxy-5β-cholanic acid) is a toxic secondary bile acid, They were FXR antagonists (IC50=0.7, 1.4 μM), EphA2 antagonists (IC50=48, 66 μM) and EphB4 antagonists (IC50=141 μM). Lithocholic acid can promote intrahepatic cholestasis and promote tumorigenesis. Lithocholic acid is a cleanser that dissolves fat for absorption and is itself absorbed. |

| 体内活性 | 方法:为研究Lithocholic acid的抗病毒作用,将LCA的衍生物-Lithocholic acid oleate(3%)和Lithocholic acid(0.5%)给药HSV-1病毒感染小鼠。 |
| 激酶实验 | Competitive ligand binding assay.: Ligand binding is performed using lysates from COS-7 cells transfected with expression plasmids for VDR or RXRα. Binding is performed overnight at 4°C in lysate buffer with 0.71 nM (18 Ci/mmol) [3H]1,25(OH)2D3 and bile acid competitor. Unbound [3H]1,25(OH)2D3 is removed by adsorption to dextran-coated charcoal and the supernatant removed for scintillation counting. Ki values are calculated from a computer fit of competition curves from triplicate assays. |
