agents which showed high antiproliferative activities against tumour cells in vitro. Moreover, compound 6a could induce late apoptosis of A549 cells at high concentrations and arrest cell cycle of A549 cells in the G0/G1 phase at tested concentrations. Also, compound 6a could inhibit the activity of wild type epidermal growth factor receptor tyrosine kinase (EGFRwt-TK) with IC50 value of 15.60 nM. Molecular
在此,设计,合成和评价了具有N,N-二乙基(氨基乙基)氨基部分的四个新颖的4-芳基氨基喹唑啉衍生物。所有合成的化合物均对肿瘤细胞具有抑制作用(SW480,A549,A431和NCI-H1975)。特别是4-(3-氯-4-(3-氟苄氧基)苯氨基)-6-(5-((N,N-二乙基(氨基乙基))氨基甲基)呋喃-2-基)喹唑啉(6a)和6 -(5-((N,N-二乙基乙基)氨基甲基)呋喃-2-基)-4-(4-(E)-(丙烯-1-基)苯基氨基)喹唑啉(6d)是有效的抗肿瘤药,显示出高在体外对肿瘤细胞具有抗增殖活性。而且,化合物6a可以在高浓度下诱导A549细胞的晚期细胞凋亡,并在测试浓度下将A549细胞的细胞周期阻滞在G0 / G1期。还,化合物6a可以抑制野生型表皮生长因子受体酪氨酸激酶(EGFRwt-TK)的活性,IC50值为15.60 nM。分子对接表明化合物6a与EGFRwt-TK形成了三个
