activation assay. A series of thiazolide derivatives were designed and synthesized to further validate the thiazolide scaffold as STAT3 inhibitors. Eight out of 25 derivatives displayed potencies greater than that of NTZ, and their STAT3 pathway inhibitory activities were found to be significantly correlated with their antiproliferative activities in HeLa cells. Derivatives 15 and 24 were observed to be more
我们通过免疫印迹分析和基于细胞的 IL-6/JAK/STAT3 通路激活测定将硝唑尼特 ( NTZ ) 鉴定为中度 STAT3 通路抑制剂。设计并合成了一系列噻唑类衍生物,以进一步验证噻唑类支架作为 STAT3 抑制剂的作用。25 种衍生物中有 8 种显示出比NTZ更强的效力,并且发现它们的 STAT3 通路抑制活性与其在 HeLa 细胞中的抗增殖活性显着相关。观察到衍生物15和24比正处于 I 期临床试验中的阳性对照WP1066更有效。与NTZ相比,15还表现出大鼠体内药代动力学参数的显着改善和对抗多种癌细胞系增殖的功效,表明这些噻唑类化合物作为靶向 STAT3 的抗肿瘤剂具有广谱作用。
