Abstract

A series of imidazole containing analogues linked in a head to tail fashion (N to C) and containing methylene linkers were synthesized and examined for their DNA binding properties. The triimidazole β-alanine linked compound 10a was shown to bind efficiently to GC rich sites on DNA covering six base pairs, which is in contrast to the tetraimidazole carboxamide compound 3, previously shown to be a poor DNA binder.
