basis of combination strategy, a novel series of EGFR inhibitors were designed and synthesized by combination of dithiocarbamic acid esters and 4-anilinoquinazolines. The effect of the synthesized compounds on cell proliferation was evaluated by MTT assay in three human cancer cell lines: MDA-MB-468, SK-BR-3 and HCT-116. Two compounds (11d and 11f) were found more potent against all three cell lines and
在联合策略的基础上,通过二硫代氨基甲酸酯与4-苯胺基喹唑啉的结合,设计合成了一系列新的EGFR抑制剂。通过MTT测定法在三种人癌细胞系:MDA-MB-468,SK-BR-3和HCT-116中评估了合成化合物对细胞增殖的作用。发现两种化合物(11d和11f)对所有三种细胞系均更有效力,而五种化合物(11a,11d – 11g))被发现对MDA-MB-468和SK-BR-3都比拉帕替尼更有效。SAR研究表明,喹唑啉C6和C7位置的取代基,二硫代氨基甲酸酯部分的胺成分和连接基极大地影响了活性。这项工作为有效的酪氨酸激酶抑制剂的制备提供了有希望的新策略。
