of the design and synthesis of minor groove binding and intercalating DNA ligands some new oligopyrrole carboxamides were synthesized. These hybrid molecules (combilexins) possess a variable and conformatively flexible spacer at the N-terminal end. As intercalating tricyclic systems acridone, acridine, anthraquinones and in a special case iminostilbene terminate the N-terminal end of the pyrrole chain
在小沟结合和嵌入DNA配体的设计和合成过程中,合成了一些新的寡吡咯羧酰胺。这些杂合分子(combilexins)在N末端具有可变的和构象柔性的间隔基。作为插入的三环系统,cri啶酮,a啶,蒽醌以及在特殊情况下的亚氨基二苯乙烯终止了吡咯链的N末端。通过NCI抗肿瘤筛选检查了细胞毒性,此外,还进行了生物物理和生化研究,以便获得有关该新系列分子的DNA结合特性和拓扑异构酶抑制作用的一些信息。
