the STAT3 protein. Moreover, MTT assay performed on A375 and HeLa, showed significant antiproliferative activity of some of synthesized compounds (3–5). The same compounds (3–5) considerably reduced STAT3 expression, as demonstrated by Western blot analysis. Our multidisciplinary approach shows that 1,4‐dimethyl‐carbazoles are potential building blocks to develop more affinity ligands of STAT3.
STAT3属于信号转导子和转录激活子(STAT)家族。已经证明STAT3在许多肿瘤中被组成性激活,在致癌和肿瘤进展中起作用。因此,它被认为是癌症治疗的潜在靶标。在这种情况下,我们设计,合成和评估了针对STAT3蛋白的1,4-二甲基咔唑衍生物。此外,MTT法对A375执行和HeLa,显示的一些合成的化合物(的显著抗增殖活性3 - 5)。相同的化合物(3 – 5如Western blot分析所示,STAT3表达大大降低。我们的多学科方法表明,1,4-二甲基咔唑是开发更多STAT3亲和配体的潜在基础。
