DNA-targeted separated bis-mustards were synthesized by attaching aniline mono-mustards at the 4- and 9-positions of the DNA-intercalating ligand 9-aminoacridine-4-carboxamide, with the intention of improving the low cross-link to monoadduct ratio found with most alkylating agents. The geometry of these compounds requires that, when the acridine binds to DNA by intercalation, one alkylating moiety
通过将苯胺单芥子附着在DNA插入配体9-氨基and啶-4-羧酰胺的4和9位上来合成以DNA为目标的分离的双芥子,目的是改善低交联与单加合物的比率与大多数烷基化剂一起发现。这些化合物的几何形状要求,当the啶通过插入与DNA结合时,一个烷基化部分被传递到每个DNA凹槽中。凝胶电泳研究表明,这些化合物中只有一个臂(可能附着在9位上)使DNA烷基化,这种烷基化特别发生在鸟嘌呤N7的主沟中。细胞系研究证实,这些化合物的细胞毒性模式(与反应性相当的未靶向苯胺双芥子气不同)是由于形成了庞大的DNA单加合物。
