Several anthranilamide-based 2-phenylcyclopropane-1-carboxamides 13a-f, 1,1'-biphenyl-4-carboxamides 14a-f and 1,1'-biphenyl-2-carboxamides 17a-f were obtained by a multistep procedure starting from the (1S,2S)-2-phenylcyclopropane-1-carbonyl chloride 11, the 1,1'-biphenyl-4-carbonyl chloride 12 or the 1,1'-biphenyl-2-carbonyl chloride 16 with the appropriate anthranilamide derivative 10a-f. Derivatives
通过从以下步骤开始的多步方法,获得了几种基于蒽酰胺的2-苯基环丙烷-1-羧酰胺13a-f,1,1'-联苯基-4-羧酰胺14a-f和1,1'-联苯基-2-羧酰胺17a-f。 (1S,2S)-2-苯基环丙烷-1-羰基氯11、1,1'-联苯基-4-羰基氯12或1,1'-联苯基-2-羰基氯16与适当的邻氨基苯甲酰胺衍生物10a -F。衍生物13a-f,14a-f和17a-f对人白血病K562细胞具有抗增殖活性。在这些衍生物中,13b,14b和17b对肿瘤细胞具有特殊的细胞毒性作用。衍生物17b对K562细胞显示出比13b和14b更好的抗肿瘤作用。为探索17b作用方式而进行的分析表明,它诱导了细胞周期的G2 / M期停滞,这是DNA损伤的结果,磷酸化ATM和γH2AX是DNA修复反应系统的两个已知标志物的增加证明了这一点。17b的作用还与ROS的产生,JNK的活化和caspase-3依赖性细胞凋亡的诱导有关。
