Signal transducer and activator of transcription (STAT3) is a proposed therapeutic target for the development of anti-cancer agents. In this report, a series of N-arylsulfonylsubstituted-1H indole derivatives were designed and synthesized as STAT3 inhibitors, their anti-proliferative activities were evaluated against a number of tumor cells, some potent compounds exhibited IC50 values less than 10 μM
信号转导子和转录激活子(STAT3)是开发抗癌药物的拟议治疗靶标。在本报告中,设计并合成了一系列N-芳基磺酰基取代的1 H吲哚衍生物作为STAT3抑制剂,评估了它们对多种肿瘤细胞的抗增殖活性,一些有效化合物的IC 50值小于10μM。进一步证实最有效的化合物4a在Tyr705处抑制STAT3磷酸化。进一步揭示4a使细胞周期停滞在G2 / M期并抑制微管蛋白聚合。这项研究描述了一系列的N-芳基磺酰基取代的1H 吲哚衍生物作为针对STAT3和微管蛋白的有效抗癌药。
