Beauveriolide III 是小鼠巨噬细胞中脂滴形成的抑制剂。
Beauveriolide III is a cyclodepsipeptide that has been found in Beauveria and an inhibitor of lipid droplet formation.1 It inhibits lipid droplet formation when used at concentrations of 3 and 10 µM, as well as inhibits cholesterol synthesis (IC50 = 0.41 µM), in primary mouse peritoneal macrophages.1,2 Beauveriolide III also inhibits acyl-coenzyme A:cholesterol acyltransferase (ACAT) activity in mouse macrophage membranes (IC50 = 5.5 µM).2 Beauveriolide III (25 and 50 mg/kg) reduces the size of aortic atherosclerotic lesions in Ldlr-/- and ApoE-/- mouse models of atherosclerosis.
