These compounds were validated for their anti-neuroinflammatory activity in BV2 cells. Experimental results reveal that the most active compound 8b can inhibit nitric oxide (NO), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β) production with IC50 values of 1.0, 2.6, and 0.5 μM, respectively. The compound can also significantly modulate the MAPK pathways through inhibiting the phosphorylation
通过组装衍生自已知试剂(例如对苯二甲酸酯和哌嗪基嘧啶)的片段,设计并合成了具有新支架的28种化合物。已经探索了许多策略来改善这些系列化合物的可药物性,例如增加支架中两个苯环之间的距离并在指定位置引入官能团。这些化合物在BV2细胞中具有抗神经炎活性。实验结果表明,活性最高的化合物8b可抑制一氧化氮(NO),肿瘤坏死因子-α(TNF-α)和白介素1β(IL-1β)的产生,IC50值为1.0、2.6和0.5μM,分别。该化合物还可以通过抑制JNK,ERK1 / 2的磷酸化来显着调节MAPK途径,和p38 MAPK,而不会干扰NF-κB通路。并行的人工膜渗透试验表明,活性最高的化合物可以克服血脑屏障(BBB)。因此,该化合物可以成为治疗阿尔茨海默氏病的有前途的先导。
