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.
We thank Dr. Giuseppe Perretta and Mr. Antonio Liccardo for their technical support, as well as the institutions that supported our laboratory (Consiglio Nazionale delle Ricerche and Università degli Studi di Napoli ‘Federico II’).
