Binding of Quercetin Derivatives toward G-Tetrads as Studied by the Survival Yield Method.

ABSTRACT: Recently, much interest has been devoted to finding effective G-quadruplex ligands, both of synthetic or natural origins, which may be of potential use in the field of cancer therapy. Among compounds of natural origin, a common flavonol quercetin has attracted notable attention. Yet, only a modest number of papers have been concerned with a comparison of quercetin conjugates binding to G-quadruplexes. In this study, we applied the survival yield (SY) method in order to compare the stability of G-tetrad complexes with quercetin and its conjugates, namely, 3-O-glycosides and O-methylated conjugates. According to the determined values of E_comδ50, flavonol glycosides bind most effectively with G-tetrads, whereas, among flavonols, 3-O-methylquercetin makes the most effective b
