site to inhibit tubulin polymerization with IC50 values 0.83 μM, but also directly bound to STAT3 protein to inhibit STAT3 phosphorylation with IC50 value of 6.84 μM. Three other compounds (TG03, DL15, and DL16) also inhibit this phosphorylation. In terms of single target inhibition, DL14 is slightly inferior to positive drugs, but it shows a good anti-tumor effect in vivo, and can inhibit >80% of
过度表达的微管蛋白和持续激活的 STAT3 在许多癌症的发展中发挥着重要作用,是潜在的治疗靶点。基于β-微管蛋白抑制剂ABT-751设计并优化了一系列4-甲氧基-N-(1-萘)苯磺酰胺衍生物,以验证STAT3和微管蛋白双靶点抑制剂是否具有更好的抗肿瘤效果。化合物DL14在体外对A549、MDA-MB-231和HCT-116细胞表现出较强的抑制活性,IC 50值分别为1.35 μM、2.85 μM和3.04 μM。进一步实验表明,DL14不仅竞争性地结合秋水仙碱结合位点抑制微管蛋白聚合,IC 50值为0.83 μM,而且直接与STAT3蛋白结合抑制STAT3磷酸化,IC 50值为6.84 μM。其他三种化合物(TG03、DL15 和 DL16)也抑制这种磷酸化。在单靶点抑制方面,DL14略逊于阳性药物,但在体内表现出良好的抗肿瘤作用,可抑制>80%的异种移植肿瘤生长。这项研究描述了一种新型的
