龙胆苦苷 用途与合成方法
龙胆苦苷是一种天然的环烯醚萜苷，能够抑制 P450 的活性，对 CYP2A6 的 IC50 和 Ki 值分别为 61 µM 和 22.8 µM；Gentiopicroside 具有抗炎和抗氧化活性。
| Target | Value |
|
CYP2A6
(in human liver microsomes) | |
|
CYP2E1
(in human liver microsomes) |
Gentiopicroside inhibits P450 activity, with an IC 50 and a K i of 61 µM and 8.12 µM for CYP2A6, also slightly inhibits CYP2E1 activity with an IC 50 of 1.6 mM, but shows no inhibition on CYP1A2 and CYP3A4. Gentiopicroside (12.5, 25 and 50 μM) inhibits RANKL-induced osteoclast formation from mouse bone marrow macrophages (BMMs) in a dose-dependent manner, blocks the expression of osteoclast-related proteins, prevents receptor activator of nuclear factor-κB ligand (RANKL)-triggered JNK and NF-κB activation. Gentiopicroside (50 μM) also inhibits RANKL-induced bone resorption.
Gentiopicroside (20, 40, and 80 mg/kg, p.o.) significantly reduces gastric ulcerindex in mice. Gentiopicroside (20, 40, and 80 mg/kg) also ovbiously decreases the levels of HSP-70, TNF-α, IL-6, MDA and increases ncreased GSH level and SOD activity. In addition, Gentiopicroside normalizes EGF and VEGF level in mice.
药理药效:具有利胆、抗炎、健胃、降压等作用。
