(II and III) ' and their new analogs represent a structurally-unique class of topoisomerase I poisons. These agents bind to the minor groove of DNA and have been shown to interfere with topoisomerase I function. Recently, a new tris benzimidazole derivative (IV) also has been designed and synthesized as a topoisomerase I poison. As part of our continuing program of synthesis of minor groove binding
