  A novel class of derivatives of resveratrol is provided which have favourable physico-chemical properties when compared with resveratrol itself. It is characterized by the presence of three carbamate functions, in which resveratrol is the oxygen-linked moiety, while the nitrogen atom carries a substituent conferring desirable characteristics to the molecule. These new compounds are especially suitable as precursors (prodrugs) and vehicles of resveratrol in preparations used as dietary integrators or in pharmaceutical compositions: they are stable towards oxidative degradation allowing for long shelf lifetimes and have suitable reactivity to regenerate and deliver resveratrol under physiological conditions.

  Resveratrol (3,5,4'-trihydroxy-trans-stilbene) is an unfulfilled promise for health care: its exploitation is hindered by rapid conjugative metabolism in enterocytes and hepatocytes; low water solubility is a serious practical problem. To advantageously modify the physicochemical properties of the compound we have developed prodrugs in which all or part of the hydroxyl groups are linked via an N-monosubstituted carbamate ester bond to promoieties derived from glycerol or galactose, conferring higher water solubility. Kinetic studies of hydrolysis in aqueous solutions and in blood indicated that regeneration of resveratrol takes place in an appropriate time frame for delivery via oral administration. Despite their hydrophilicity some of the synthesized compounds were absorbed in the gastrointestinal tract of rats. In these cases the species found in blood after administration of a bolus consisted mainly of partially deprotected resveratrol derivatives and of the products of their glucuronidation, thus providing proof-of-principle evidence of behavior as prodrugs. The soluble compounds largely reached the lower intestinal tract. Upon administration of resveratrol, the major species found in this region was dihydroresveratrol, produced by enzymes of the intestinal flora. In experiments with a fully protected (trisubstituted) deoxygalactose containing prodrug, the major species were the prodrug itself and partially deprotected derivatives, along with small amounts of dihydroresveratrol. We conclude that the N-monosubstituted carbamate moiety is suitable for use in prodrugs of polyphenols.
