Abstract
A series of 2'-heterocyclic derivatives of 5-phenyl-2,5'-1H-bibenzimidazole s were evaluated for topoisomerase I poisoning activity and cytotoxicity. T opo I poisoning activity was associated with 2'-derivatives that possessed a hydrogen atom capable of hydrogen bond formation, suggesting that the int eratomic distances between such hydrogen atoms and the heteroatoms on the a djacent benzimidazole influence activity.
