A novel series of benzo[d]thiazole-2-carboxamide derivatives have been de novo designed based on virtual screening methods. The target compounds were synthesized and evaluated for the cytotoxicity against epidermal growth factor receptor high-expressed cancer cell lines (A549, HeLa, and SW480), epidermal growth factor receptor low-expressed cell line (HepG2) and human liver normal cell line (HL7702)
新型苯并[ d]基于虚拟筛选方法从头设计了]噻唑-2-羧酰胺衍生物。合成目标化合物并评估其对表皮生长因子受体高表达癌细胞系(A549,HeLa和SW480),表皮生长因子受体低表达细胞系(HepG2)和人肝正常细胞系(HL7702)的细胞毒性)。几种目标化合物已显示出对A549,HeLa和SW480的中等至极强的效力,并且对HepG2的细胞毒性作用较弱,这表明它们可能是表皮生长因子受体抑制剂。而且它们几乎没有表现出针对HL7702的任何活性,这表明它们很可能会克服针对正常细胞的非特异性毒性。特别是化合物6- [2-(二乙氨基)-2-氧乙氧基] -N-(呋喃-2-基甲基)苯并[ d ]噻唑-2-羧酰胺(6i)被确认为有前途的药物,表现出最强的细胞毒活性,对A549,HeLa,IC 50的IC 50值为4.05、12.17、6.76μM。和SW480细胞系。
