treatment of selective cancers. We report here the design and synthesis of a novel series of 4,5-dihydro-1H-thieno [2′,3′:2,3]thiepino[4,5-c]pyrazole-3-carboxamide derivatives and the screening for their inhibitory activity on the EGFR high-expressing human A549 cell line using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT). A Docking simulation was performed to fit compound 6g and gifitinib
表皮生长因子受体 (EGFR) 的过度表达(称为上调)或过度活跃与多种癌症相关,已成为治疗选择性癌症的有吸引力的分子靶标。我们在此报告了一系列新型 4,5-dihydro-1H-thieno [2',3':2,3]thiepino[4,5-c]pyrazole-3-carboxamide 衍生物的设计和合成以及筛选使用 3-(4,5-二甲基噻唑-2-基)-2,5-二苯基溴化四唑 (MTT) 对 EGFR 高表达人 A549 细胞系的抑制活性。进行对接模拟以将化合物6g和吉非替尼拟合到EGFR中以确定可能的结合模型,并且6g和吉非替尼的结合位点和模式构象完全相似,两种化合物通过与MET769的氢键相互作用而稳定。结合生物活性评估,化合物6g显示出最有效的抑制活性(A549的IC50 = 9.68 ± 1.95 μmol·L–1)。最后,发现了 4,5-二氢-1H-噻吩并[2',3':2,3]噻吩并[4
