We studied complex formation of flavonoids quercetin and taxifolin with iron(II) and the complex influence on phase transitions of phospholipid bilayer. UV–Vis spectroscopy revealed that the stoichiometry of flavonoid/iron complexes was equal to 3:2 and 2:1. Molecular modeling and experimental measurements demonstrated the increase of flavonoids lipophilicity after the complex formation. A considerable influence of quercetin–iron complex on Palmitoyl–Oleoyl–Phosphatidylethanolamine transitions from bilayer to hexagonal HII phase was detected by differential scanning calorimetry. The obtained data are related to flavonoid/iron complexes bioavailability, their influence on cell membrane functioning, and should be considered in designing liposomal vehicles for drug and gene delivery.
► We studied lipophilicity of flavonoid/iron complexes with different stoichiometry. ► The lipophilicity increases for complexes with flavonoid/iron equal to 2:1 or 3:2. ► The lipophilic complexes influence phase transitions of phospholipids.
