1H-Benzimidazole derivatives as mammalian DNA topoisomerase I inhibitors.
Benzimidazole is one of the most important heterocyclic groups manifesting various biological properties, such as antibacterial, antifungal, antimicrobial, antiprotozoal and antihelmintic activities. Several benzimidazole derivatives are also active as inhibitors of type I DNA topoisomerases. In this study, three 1H-benzimidazole derivatives with different electronic characteristics at position...

متن کاملNew benzimidazole derivatives as topoisomerase I inhibitors--synthesis and fluorometric analysis.
A series of new benzimidazole derivatives with potential anticancer activity were tested as a new topoisomerase I inhibitors. The fluorometric method was used to determine in vitro the quantitative level of plasmid DNA relaxation by these compounds. Optimization of the fluorometric system and validation of the established analytical method were performed. Out of benzimidazole derivatives which ...
متن کاملSome new bi- and ter-benzimidazole derivatives as topoisomerase I inhibitors.
The discovery of DNA topoisomerases has added a new dimension to the study of anticancer drugs. In the last years detailed investigation of bi- and ter-benzimidazole derivatives revealed that these compounds are a new class of topoisomerase I inhibitors that poisons mammalian topoisomerase I. In this context a survey about topoisomerase I poisoning activity and cytotoxicity of bi- and ter-benzi...
متن کاملXanthocidin derivatives as topoisomerase IIα enzymatic inhibitors.
Few studies have examined xanthocidin, a biotic isolated from Streptomyces xanthocidicus in 1966, because its supply is limited. Based on its chemical structure, xanthocidin has the potential to become a lead compound in the production of agrochemicals and anti-cancer drugs; however, it is unstable under both basic and acidic conditions. We recently established the total synthesis of xanthocidi...
