In the context of the design and synthesis of DNA ligands, some new hetarene annelated carbazoles were synthesized. As lead structure the intercalating tetracyclic systems pyrido[2,3-a]- and pyrido[4,3-a]-carbazoles and in one case a thieno[2,3-a]-carbazole were taken into account. A dialkyl amino amidic chain was introduced to the planar chromophoric system with the intent to generate minor groove
在DNA配体的设计和合成过程中,合成了一些新的戊烯退火的咔唑。作为铅结构,考虑了插入的四环体系吡啶并[2,3- a ]-和吡啶并[4,3- a ]-咔唑,在一种情况下考虑了噻吩并[2,3- a ]-咔唑。将二烷基氨基酰胺链引入平面发色体系,目的是产生较小的凹槽结合性能。通过NCI抗肿瘤筛选检查了某些化合物的细胞毒性。此外,进行了生物物理和生化研究,以便获得有关此新系列分子的DNA结合特性和对DNA相关功能酶的抑制作用的一些信息。
