This research studied the structure-activity relationship of beta-carboline derivatives as antitumor agents, in which 41 synthesized compounds and their cytotoxicity to tumor and normal cell lines were assayed. It was proved that substituent in position-9 of the beta-carboline ring could reinforce the DNA intercalating ability and consequently cytotoxicity to tumor cell lines, and the amidation of
本研究研究了β-咔啉衍
生物作为抗肿瘤剂的构效关系,分析了41种合成化合物及其对肿瘤和正常
细胞系的细胞毒性。事实证明,β-咔啉环第9位的取代基可增强DNA的插入能力,从而增强对肿瘤细胞的细胞毒性,而靶向第3位侧链的DNA末端的
氨基酰胺化则会削弱这些化合物的DNA嵌入活性,从而引发了对肿瘤
细胞系而不是正常
细胞系的细胞毒选择性。此外,这些化合物引起的S和G2-M阻滞证实,它们可以靶向DNA并导致Hela细胞中的DNA破坏。简而言之,
