生产及用途
Danthron (Chrysazin, Antrapurol) 通过激活 AMPK 来调节葡萄糖和脂质代谢。Danthron是从传统中药大黄中提取的天然产物。Danthron曾经是一种泻药,现在被用作合成润滑剂中的抗氧化剂,实验抗肿瘤剂的合成,杀真菌剂和制造染料的中间体。
Danthron (0.1, 1, and 10 μM) dose-dependently promotes the phosphorylation of AMPK and acetyl-CoA carboxylase (ACC) in both HepG2 and C2C12 cells. Meanwhile, Danthron treatment significantly reduces the lipid synthesis related sterol regulatory element-binding protein 1c (SREBP1c) and fatty acid synthetase (FAS) gene expressions, and the total cholesterol (TC) and triglyceride (TG) levels. In addition, Danthron treatment efficiently increases glucose consumption. Danthron effectively reduces intracellular lipid contents and enhances glucose consumption in vitro via activation of AMPK signaling pathway. 10 μM Danthron/24 h is safe for HepG2 cells. With 80% confluence, HepG2 cells are incubated with Danthron (0.1-10 μM) in FBS-Free media for 8 h. Subsequently, cells are harvested for Western blot assay. Danthron increases the p-AMPK protein in a dose-dependent manner, and no changes in t-AMPK protein are observed. Danthron inhibits 9-cis retinoic acid (9cRA)-induced retinoic X receptor α (RXRα) transactivation by IC 50 at 0.11 μM. To further clarify the stoichimetric ratio of Danthron binding to RXRα-ligand-binding domain (LBD), isothermal titration calorimetry (ITC) experiment is performed. The K D value of Danthron binds to RXRα-LBD by ITC experiment is determined at 7.5 μM.
Danthron functions as an insulin sensitizer in vivo. Danthron improves insulin sensitivity in diet-induced obese (DIO) mice. The insulin tolerance test result shows that Danthron (5 mg/kg) treated diet-induced obesity mice exhibit lower glucose levels after insulin challenge, compared with the control vehicle-treated group.
