We report the development of a chemical modification method of general applicability to polyphenols, which increases solubility to influence absorption. Glucosyl groups were added to the resveratrol kernel via a succinate linker, yielding 3,4',5-tri-(alpha-D-glucose-3-O-succinyl) resveratrol. The construct was only slowly hydrolyzed in acid and at pH 6.8, but it was destroyed by blood esterases in less than 1h. In rats its administration resulted in a blood concentration versus time curve shifted to longer times in comparison to resveratrol, a useful modulation of pharmacokinetics. The area-under-curve parameter and the metabolite mix were similar to those of resveratrol. The method may be advantageously employed to solubilize other polyphenols and to make them more palatable.

Abstract: | We report the development of a chemical modification method of general applicability to polyphenols, which increases solubility to influence absorption. Glucosyl groups were added to the resveratrol kernel via a succinate linker, yielding 3,4',5-tri-(alpha-D-glucose-3-O-succinyl) resveratrol. The construct was only slowly hydrolyzed in acid and at pH 6.8, but it was destroyed by blood esterases in less than 1h. In rats its administration resulted in a blood concentration versus time curve shifted to longer times in comparison to resveratrol, a useful modulation of pharmacokinetics. The area-under-curve parameter and the metabolite mix were similar to those of resveratrol.
