生物活性
Ro 48-8071是一种Oxidosqualene cyclase小分子抑制剂,IC50值为6.5nM。Ro 48-8071 blocked human liver OSC and cholesterol synthesis in HepG2 cells in the nanomolar range. In cells it triggered the production of monooxidosqualene, dioxidosqualene, and epoxycholesterol. It was safe in hamsters, squirrel monkeys and Gottingen minipigs at pharmacologically active doses, lowering LDL approximately 60% in hamsters, and at least 30% in the two other species, being at least as efficacious as safe doses of simvastatin. Ro 48-8071 did not reduce coenzyme Q10 levels in liver and heart of hamsters, and importantly did not trigger an overexpression of hepatic HMG-CoA reductase, squalene synthase, and OSC itself. Ro 48-8071 dose-dependently inhibited 17β-estradiol (E2)-induced ERα responsive luciferase activity (IC50 value, ~10 μM), under conditions that were non-toxic to the cells. Ro 48-8071 was less effective against ERβ-induced luciferase activity. Androgen receptor (AR) mediated transcriptional activity was also reduced by Ro 48-8071.

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
