PPAR-γ active sites. Additionally, the relationship between geometry and electronic properties of chemical compounds were investigated using HOMO-LUMO, MEP, and NBO analysis. The compounds were synthesized by established synthetic schemes and structurally analyzed using IR, 1H NMR, 13C NMR and mass spectral analysis. The binding affinity of the compounds with the target protein (PPAR-γ) was further confirmed
在此,我们描述了基于结构的新型格列酮类药物的设计和合成,其具有咪唑啉 2、4-二酮和 2-硫代噻唑烷-4-一环结构作为中枢 PPAR-γ 结合和激活的基本支架。PPAR-γ/辅激活因子 PGC-1α 的中枢激活在神经退行性疾病中产生有益作用。这些化合物经过合理设计,特别强调毒性参数并经过计算筛选。总共从基于咪唑啉 2、4-二酮和 2-硫代噻唑烷-4-一环结构设计的格列酮的内部库中选择了四种化合物,用于进一步研究 PPAR-γ 激活。设计的格列酮与 PPAR-γ 蛋白的分子对接揭示了与 Ser289、His323、Tyr327、和 Tyr473 与标准吡格列酮相比。蛋白质-配体复合物的结构稳定性通过分子动力学 (MD) 模拟 (100 ns) 得到证实,结果表明与 PPAR-γ 活性位点的显着相互作用。此外,还使用 HOMO-LUMO、MEP 和 NBO 分析研究了化合物的几何形状和电子
