贝特类降血脂药物的合成及降脂活性研究
Synthesis and Lipid-Lowering Activity of Novel Fibrate Lipid-Lowering Drugs
贝特类降血脂药物具有高活性和作用速度快等特点,基于蒙药材荜茇的有效成分和药理作用对贝特类药物进行结构修饰,以胡椒酸酰氯、胡椒碱、苯甲酰氯及其衍生物为反应底物,设计并合成了4种新型贝特类衍生物,其结构均经1H NMR、13C NMR和HRMS表征。通过噻唑蓝(MTT)方法测定了4种化合物对293细胞的IC50值,并通过脂质体转染方法(Lipofectamine 2000),转染PPARα/γ、RXR和PPRE-luciferase表达质粒至哺乳动物细胞系293细胞中进行活性测试,结果表明,化合物Ⅰ、Ⅱ、Ⅲ、Ⅳ的IC50值分别为130、159、530、479 nmol/L。激活PPARα的活性依次为:Ⅱ>非诺贝特>Ⅳ>Ⅰ>Ⅲ,4种新合成化合物均有生物学活性。本研究为进一步研发药理活性更高、作用更广泛和副作用更低的贝特类降血脂药物提供了参考依据。
Fibrates, a class of lipid-lowering drugs, have the characteristics of high activity and fast action.Based on the study of the active ingredients and pharmacological effects of the Mongolian medicinal herb, the structure of fibrate based drugs was modified to synthesize fibrate derivatives containing monomers of the active ingredients of Piper longum.Vanillin, benzoic acid, and their derivatives were used as the substrates to design and synthesize four novel beta derivatives.Their structures were characterized and confirmed by 1H NMR, 13C NMR, and HRMS.The IC50 values of four compounds on 293 cells were determined by MTT assay, and the activity of mammalian cell line 293 cells co-transfected by PPAR α/γ, RXR, PPRE-luciferase expression plasmids was tested by liposome transfection method (Lipofectamine 2000).The results show that the IC50 values of compounds Ⅰ, Ⅱ, Ⅲ and Ⅳ respectively are 130, 159, 530 and 479 nmol/L.The activation activity of PPARα is in the order of Ⅱ > fenofibrate > Ⅳ > Ⅰ > Ⅲ.The four newly synthesized compounds have biological activity.The study provides a reference for further research and development of blood lipid lowering drugs such as beta blockers with higher pharmacological activity, wider range of effects, and lower side effects.
