derivatives as a new series of PPARδ agonists using docking-based virtual screening methods. In the present study, we found that introduction of a pyrrolidine group into the 4-position of their central piperidine rings enhances hPPARδ activity and subtype selectivity. This led to the discovery of 21 having strong PPARδ agonist activity (EC50 = 3.6 nM) with excellent ADME properties. Furthermore, 21 significantly
过氧化物酶体增殖物激活受体δ(PPARδ)被认为是治疗动脉粥样硬化等代谢性疾病的药物靶点,但目前尚无可供临床使用的PPARδ激动剂。我们之前曾报道过使用基于对接的虚拟筛选方法发现了哌啶基/哌嗪基苯并噻唑衍生物作为一系列新的 PPARδ 激动剂。在本研究中,我们发现将吡咯烷基团引入其中心哌啶环的4位可增强hPPARδ活性和亚型选择性。这导致发现21具有强 PPARδ 激动剂活性 (EC 50 = 3.6 nM) 和优异的 ADME 特性。此外, 21显着抑制了 LDLr-KO 小鼠中 50-60% 的动脉粥样硬化进展,并降低了 MCP-1 的血清水平。
