J. Pastor et al., SYNTHESIS OF NEW AZINO FUSED BENZIMIDAZOLIUM SALTS - A NEW FAMILY OF DNA INTERCALATING AGENTS .1., Bioorganic & medicinal chemistry letters, 5(24), 1995, pp. 3043-3048
A series of new pyrido[1,2-a]- and pyridazino[1,6-a]benzimidazolium sa
lts have been synthesized from readily available 1,3-disubstituted 2-a
lkylbenzimidazolium salts. Their affinity to DNA and in vitro cytotoxi
city versus HT-29 have been tested. The initial results show that the
title compounds are a new family of intercalating agents.
