which indicated the compound 9o could induce remarkable apoptosis of A549 and cells in a dose dependent manner. Structure-activity relationships (SARs) and docking studies indicated that replacement of the cinnamamide group by aryl semicarbazone scaffolds slightly decreased the anti-tumor activity. The results suggested that hydroxy substitution at C-4 had a significant impact on the activity and replacement
设计,合成了两个带有芳基半脲酮骨架的喹唑啉衍生物系列(9a-o和10a-o),并评估了其对四种癌细胞系(A549,HepG2,MCF-7和PC-3)的IC50值。进一步评估选择的化合物9o对EGFR激酶的抑制活性。其中四种化合物显示出优异的细胞毒性活性和选择性,IC50值在个位数μM至纳摩尔范围内。它们中的两个等于对一个或多个细胞系比阳性对照阿法替尼更具活性。最有前途的化合物9o对A549,HepG2,MCF-7和PC-3癌细胞系和EGFR激酶表现出最佳活性,IC50值为1.32±0.38μM,0.07±0.01μM,0.91±0.29μM和4.89± 0.69μM,比阿法替尼(1.40±0.83μM,1.33±1.28μM,2.63±1.06μM和3.96±0.59μM)活性更高,分别。最有前途的化合物9o(IC50 56nM)对EGFR激酶的活性略低于阳性化合物afatinib(IC50
