简介内容:BIBB 515 is a selective and potent inhibitor of OSC in vivo with an ED50 value of and mg/kg in rats and mice, respectively. 2, 3-Oxidosqualene cyclase (OSC) is an important enzyme in the biosynthesis of animal, plant, and fungal sterols. OSC catalyzes the conversion of (3S)-2, 3-oxidosqualene to lanosterol, a precursor to cholesterol, in mammals and fungi.
