responses, and apoptosis. Inhibiting ASK1 is an attractive strategy for treating diseases such as nonalcoholic steatohepatitis and multiple sclerosis. Here, we explored and synthesized a series of new skeleton compounds containing hydrogenated indole, indole, benzimidazole, tetrahydroquinoxaline, benzoxazine, tetrahydroquinoline, phenol, nitrobenzene, pyridine as ASK1 inhibitors. Among them, 44a and 44b
细胞凋亡信号调节激酶 1 (ASK1,也称为 MAP3K5) 是丝裂原活化蛋白激酶 (MAPK) 信号通路的成员,参与细胞存活、分化、应激反应和细胞凋亡。抑制 ASK1 是治疗非酒精性脂肪性肝炎和多发性硬化症等疾病的一种有吸引力的策略。在这里,我们探索并合成了一系列含有氢化吲哚、吲哚、苯并咪唑、四氢喹喔啉、苯并恶嗪、四氢喹啉、苯酚、硝基苯、吡啶作为ASK1抑制剂的新型骨架化合物。其中,含有2-三唑基吡啶片段的44a和44b表现出较强的抑制活性,IC 50值分别为 0.15 和 0.31 μM。此外,44a和44b在不同浓度下的细胞存活率均大于90%,尤其是在0.05、0.1和0.8 μM时,其细胞存活率高于GS-4997,说明它们在人体正常使用中表现出良好的安全性。肝脏 LO2 细胞。流式细胞术结果显示,44a和44b显着阻断了G1期周期的进程。油红O染色实验表明, 44a浓度为8μM时,
