A series of cobalt complexes of the potent DNA minor groove alkylator 1-(chloromethyl)-3-(5,6,7-trimethoxyindol-2-ylcarbonyl)-2,3-dihydro-1H-pyrrolo[3,2-f]quinolin-5-ol (seco-6-azaCBI-TMI) were prepared from a series of N-substituted cyclen ligands. The final N-substituted complexes carried formal overall charges ranging from +2 to −2 and showed limited improvements in solubility. They showed similar
强大的DNA小沟烷基化剂1-(氯甲基)-3-(5,6,7-三甲氧基吲哚-2-基羰基)-2,3-二氢-1 H-吡咯并[3,2- f由一系列的N-取代的cycln配体制备对喹啉-5-醇(seco -6-azaCBI-TMI)。最终的N-取代的配合物携带形式上的总电荷,其范围为+2至-2,并且显示出有限的溶解度提高。他们显示出与未取代的cycln配体的复合物相似的稳定性,并且游离烷基化剂的细胞毒性有较大但可变的衰减(2–30倍),而未取代的配体则为150倍。然而,它们的氧化/低氧比(2-22倍)可与未取代的环素复合物相比(5)。
