| Abstract: | New amidino‐benzimidazolyl‐substituted bis‐1,2‐(2‐thienyl)ethenes ( 4, 5 , and 6 ) and benzo1,2‐ b:4,3‐ b′]dithiophenes ( 8, 9 , and 10 ) were prepared by the condensation of amidino‐substituted o‐phenylene diamines with corresponding dialdehydes ( 3 and 7 ). All prepared amidino‐benzimidazolyl‐substituted compounds are of particular interest, because they can serve as intercalators or groove binders on DNA in anticancer therapy. © 2003 Wiley Periodicals, Inc.
