Synthesis of a novel benzodifuran derivative and its molecular recognition of poly rA RNA

Biol Chem. 2013 Sep;394(9):1235-9. doi: 10.1515/hsz-2013-0154.

Abstract

In this manuscript, we describe a synthetic approach to a novel benzodifuran derivative as well as CD studies regarding its ability to interact with DNA and RNA. After the chemical synthesis and ESI-MS and NMR characterization, this heteroaromatic molecule was investigated by CD spectroscopy in order to evaluate it as a potential nucleic acid binder. Interestingly, the benzodifuran compound was found to be able to induce conformational changes in both DNA and RNA homoadenine molecules forming in the latter case a complex with a 6:1 benzodifuran/nucleobase stoichiometric ratio, as evidenced by CD titration experiments.
