文摘目的:得到治疗效果好,副作用小的PPAR泛激动剂。方法:用core hopping的方法对LY465608中间链部分和尾链部分进行结构替换。得到新的化合物并与3个蛋白质受体进行分子对接。应用分子动力学模拟先导化合物与PPAR-α、β、γ受体的相互作用情况。基于Lipinski’s rule of five,对得到的先导化合物进行ADME预测。结果:对接结果表明得到的目标化合物能与PPAR-α、β、γ活性位点区域的氨基酸残基形成氢键,使AF-2螺旋稳定于激活构象。分子动力学模拟结果表明模拟过程中受体与激动剂复合物体系是稳定的。ADME预测发现它们体内的吸收、分布、代谢和排泄情况符合作为药物的一般特点。结论:得到的8个化合物可以作为PPAR泛激动剂予以进一步的研究。
