potent and selective FABP4 inhibitors by applying a structure-based design strategy. The binding affinities of compounds 16dk, 16do and 16du to FABP4, at the molecular level, are equivalent to or even better than that of BMS309403. The X-ray crystallography complemented by the isothermal titration calorimetry studies revealed the binding mode of this series of inhibitors and the pivotal network of
脂肪酸结合蛋白4(FABP4)在代谢和炎症过程中起关键作用,因此是免疫代谢疾病(例如糖尿病和动脉粥样硬化)的潜在治疗靶标。在这里,我们报告了通过应用基于结构的设计策略,将萘-1-磺酰胺衍生物鉴定为新型,有效和选择性的FABP4抑制剂。化合物16dk,16do和16du的结合亲和力在分子水平上,对FABP4的抗性等于或什至优于BMS309403。X射线晶体学等温滴定量热法研究的补充,揭示了这一系列抑制剂的结合模式以及FABP4结合口袋中有序水分子的关键网络。此外,化合物16dk和16do在肝微粒体中表现出良好的代谢稳定性。进一步的广泛体内研究表明,通过降低空腹血糖和血清脂质水平,增强胰岛素敏感性以及减轻肥胖糖尿病患者的肝脂肪变性,dbd和16do可以显着改善葡萄糖和脂质代谢(db / db) 老鼠。
