cells than N,N'-dialkyl-9,9'-biacridylidenes 7-12, revealing that conjugation of the heteroaromatic system plays a significant role on the effective distribution of the compound in the intracellular environment. Cellular investigation of long alkyl derivatives against cell migration exhibited 40-50% wound healing effects and cytoplasm diffusion, while compounds with shorter alkyl chains were accumulated
cri啶酮衍生物的抗癌活性引起了越来越多的兴趣,因此,已经开发了多种属于该家族的取代类似物并对其抗癌性质进行了评估。研究了一系列具有可变烷基链的N-烷基-啶酮1-6和N,N'-二烷基-9,9'-双丙烯酰亚胺7-12在中性和酸性条件下的拓扑异构酶I活性及其结合小牛胸腺的能力和可能的自由基捕获抗氧化活性。发现在中性pH下,两类化合物的拓扑异构酶I活性相似,而在酸性条件下,观察到插层增强。N-烷基-啶酮衍生物1-6与N,N'-di烷基-9,9'相比,对MCF-7人乳腺上皮癌细胞表现出更强的剂量依赖性细胞毒性活性 -双丙烯酰亚胺7-12,揭示杂芳族系统的缀合对化合物在细胞内环境中的有效分布起重要作用。长烷基衍生物对细胞迁移的细胞研究显示出40-50%的伤口愈合作用和细胞质扩散,而具有较短烷基链的化合物则同时在细胞核和细胞质中积累。所有的N,N'-二烷基-9,9'-双丙烯啶都显示出对DPPH或ABT
