2-benzyl-1H-benzo[de]isoquinoline-1,3(2H)-dione (4), which showed the best cytotoxic effects, was evaluated by flow cytometry, and a significant increase was observed in the proportion of cells in the subG0/G1, S and G2/M phases accompanied by a significant decrease in the G0/G1 phases. Then the mechanism involved on the death route (necrosis or apoptosis) was evaluated the by bromide and acridine orange
环酰亚胺是通过有机合成获得的一大类化合物,包括几个子类(琥珀酰亚胺,马来酰亚胺,戊二酰亚胺,邻苯二甲酰亚胺,萘二甲酰亚胺及其衍生物)。最近,一些环酰亚胺衍生物已显示出作为潜在的抗肿瘤剂,如Mitonafide和Amonafide重要的结果。基于这一事实,我们研究了九种环状酰亚胺衍生物对鼠黑色素瘤细胞(B16F10)的抗肿瘤特性,其中四种尚未公开。最初,MTT分析用于选择具有最佳细胞毒性潜力的化合物。选择之后,化合物2-苄基-1 H-苯并[ de ]异喹啉-1,3(2 H)-二酮(4通过流式细胞术评估了显示出最佳细胞毒性作用的),观察到subG0 / G1,S和G2 / M期的细胞比例显着增加,同时G0 / G1相的显着减少。然后,通过溴化物和a啶橙法以及膜联蛋白V-FITC细胞凋亡检测试剂盒对涉及死亡途径(坏死或凋亡)的机制进行了评估。这些结果证实了在亚G0 / G1期中观察到的B16F1
