Microglia-mediated neuroinflammation plays an important role in ischemic stroke (IS). In this work, a series of novel indole and indazole-piperazine pyrimidine derivatives with anti-neuroinflammatory and neuroprotective activities were designed and synthesized for treatment of IS. Among these compounds, 5j displayed the most attractive cytoprotective effect against oxygen-glucose deprivation/reoxygenation
小胶质细胞介导的神经炎症在缺血性中风 (IS) 中起重要作用。在这项工作中,设计并合成了一系列具有抗神经炎症和神经保护活性的新型吲哚和吲唑-哌嗪嘧啶衍生物,用于治疗 IS。在这些化合物中,5j对 BV2 细胞中的氧 - 葡萄糖剥夺/复氧 (OGD/R) 诱导的损伤表现出最有吸引力的细胞保护作用。同时,它显着改善了炎症介质的释放,包括肿瘤坏死因子-α(TNF-α)、白细胞介素-1β(IL-1β)、IL-6、一氧化氮(NO)和前列腺素E2(PGE2)从脂多糖中的释放。 (LPS) 诱导的 BV2 细胞。此外,5j可减少 TNF-α 和 IL-1β 的释放,形成 LPS 诱导的小鼠脑神经炎症模型。作为 cyclooxygenase-2 (COX-2, IC 50 = 92.54 nM) 和 5-lipoxygenase (5-LOX, IC 50 = 41.86 nM) 的有效抑制剂 ,5j抑制小胶质细胞的
