The synthesis, physico-chemical properties and biological effects of a new class of naphthalene diimides (NDIs) capable of reversibly binding telomeric DNA and alkylate it through an electrophilic quinone methide moiety (QM), are reported. FRET and circular dichroism assays showed a marked stabilization and selectivity towards telomeric G4 DNA folded in a hybrid topology. NDI–QMs’ alkylating properties
据报道,新型萘二酰亚胺(NDI)的合成,理化性质和生物学效应能够可逆地结合端粒DNA并通过亲电子醌甲基化物部分(QM)将其烷基化。FRET和圆二色性分析显示出对杂化拓扑中折叠的端粒G4 DNA的显着稳定性和选择性。NDI-QMs的烷基化特性显示其对单个核苷具有良好的反应性,并且对端粒G4具有选择性。选定的NDI能够通过引起端粒功能障碍和端粒酶表达下调来显着损害黑素瘤细胞的生长。这些发现表明,我们的杂化配体烷基化NDI可作为开发新型靶向抗癌疗法的可能工具。
