A series of N-mustards, which was conjugated to mono- or bis-naphthalimides with a flexible amine link, were synthesized and evaluated for cytotoxicity against five cancer cell lines (HCT-116, PC-3, U87 MG, Hep G2 and SK-OV-3). Several compounds displayed better activities than the control compound amonafide. Further evaluations by fluorescence spectroscopy studies and DNA-interstrand cross-linking assays revealed that the derivatives showed both alkylating and intercalating properties. Among the derivatives, the bis-naphthalimide N-mustard derivative 11b was found to exhibit the highest cytotoxic activity and DNA cross-linking ability. Both 11b and 7b induce HCT-116 cell apoptosis by S phase arrest.
合成了一系列N-芥子,控制与单体或双萘亚胺通过灵活的胺链连接,并评估其对五种癌症细胞系(HCT-116、PC-3、U87 MG、Hep G2和SK-OV-3)的细胞毒性。几种化合物的活性超过了对照化合物amonafide。进一步通过荧光光谱研究和DNA链间交联实验的评估显示,这些衍生物具有烷基化和插入特性。在这些衍生物中,双萘亚胺N-芥子衍生物11b被发现表现出最高的细胞毒活性和DNA交联能力。11b和7b都通过S期阻断诱导HCT-116细胞凋亡。
