STAT3 signaling pathway has been validated as a vital therapeutic target for cancer therapy. Based on the novel STAT3 inhibitor of a benzyloxyphenyl-methylaminophenol scaffold hit (1) discovered through virtual screening, a series of analogues had been designed and synthesized for more potent inhibitors. The preliminary SAR had been discussed and the unique binding site in SH2 domain was predicted
STAT3信号通路已被证实是癌症治疗的重要治疗靶标。基于通过虚拟筛选发现的新型苄氧基苯基-甲基氨基苯酚支架命中的STAT3抑制剂(1),设计并合成了一系列类似的抑制剂,用于更有效的抑制剂。已经讨论了初步的SAR,并通过分子对接预测了SH2结构域中的独特结合位点。其中,化合物4a和4b对IL-6 / STAT3信号通路的表现优于命中化合物(1),IC 50值分别低至7.71μM和1.38μM。化合物4a还显示了对MDA-MB-468细胞系的有效抗增殖活性,IC 50值为9.61μM。我们认为,这些苄氧基苯基-甲基氨基苯酚衍生物代表了一种独特的机制来询问STAT3以及潜在的结构类型,以供进一步探索。
