cancer cell lines (A549, PC-3, MCF-7 and Hela). Two selected compounds (10e, 10k) were further evaluated for the inhibitory activity against EGFR and VEGFR2/KDR kinases. Seven of the compounds showed excellent cytotoxicity activity and selectivity with the IC50 values in single-digit μM to nanomole range. Three of them are equal to more active than positive control afatinib against one or more cell lines
设计,合成并评估了两个带有肉桂酰胺部分的afatinib衍生物系列(10a – n和11a – h),并评估了其对四种癌细胞系(A549,PC-3,MCF-7和Hela)的IC 50值。进一步评估了两种选择的化合物(10e,10k)对EGFR和VEGFR2 / KDR激酶的抑制活性。其中七个化合物表现出出色的细胞毒性活性和选择性,IC 50值在个位数μM到纳摩尔范围内。它们中的三个等于比阳性对照afatinib对一种或多种细胞系更有活性。最有前途的化合物10k表现出对A549,PC-3,MCF-7和Hela癌细胞系和EGFR激酶的最佳活性,IC 50值分别为0.07±0.02μM,7.67±0.97μM,4.65±0.90μM和4.83±1.28μM。分别比阿法替尼(0.05±0.01μM,4.1±2.47μM,5.83±1.89μM和6.81±1.77μM)活性更高。化合物10e(IC 50
