PPARα and PPARγ have been the most widely studied Peroxisome proliferator-activated receptor (PPAR) subtypes due to their important roles in regulating glucose, lipids, and cholesterol metabolism. By combining the lowering serum triglyceride levels benefit of PPARα agonists (such as fibrates) with the glycemic advantages of the PPARγ agonists (such as TZD), the dual PPAR agonists approach can both improve the metabolic effects and minimize the side effects caused by either agent alone, and hence, has become a promising strategy for designing effective drugs against type-2 diabetes. In this study, by means of virtual screening, ADMET prediction and molecular dynamics (MD) simulations techniques, one compound-ASN15761007 with high binding score, low toxicity were gained. It was observed by MD simulations that ASN15761007 not only possessed the same function as AZ242 did in activating PPARα and BRL did in activating PPARγ, but also had more favorable conformation for binding to the two receptors. Our results provided an approach to rapidly produce novel PPARα/γ dual agonists which might be a potential lead compound to develop against insulin resistance and hyperlipidemia.
PPARα 和 PPARγ 是研究最广泛的过氧化物酶体增殖物激活受体 (PPAR) 亚型,因为它们在调节葡萄糖、脂质和胆固醇代谢方面发挥着重要作用。通过将 PPARα 激动剂(如贝特类药物)降低血清甘油三酯水平的益处与 PPARγ 激动剂(如 TZD)的血糖优势相结合,双重 PPAR 激动剂方法可以改善代谢作用并最大程度地减少单一药物引起的副作用,因此,它已成为设计针对 2 型糖尿病有效药物的一种很有前途的策略。在这项研究中,通过虚拟筛选、ADMET 预测和分子动力学 (MD) 模拟技术,获得了一种具有高结合评分、低毒性的化合物 ASN15761007。通过 MD 模拟观察到,ASN15761007 不仅具有与 AZ242 激活 PPARα 和 BRL 激活 PPARγ 相同的功能,而且还具有更有利于与两种受体结合的构象。我们的结果提供了一种快速产生新型 PPARα/γ 双重激动剂的方法,这可能是开发针对胰岛素抵抗和高血脂的潜在先导化合物。
