Resveratrol possesses a wide range of biological properties, among them antioxidant, cardioprotective, neuroprotective, anti-inflammatory and anticancer activities.
Resveratrol possess many biological properties, but the best described resveratrol property is their capacity to act as a potent antioxidant. Resveratrol antioxidant activity depends upon the arrangement of functional groups on nuclear structure. Therefore, configuration, substitution, and total hydroxyl groups number substantially influence several mechanisms of antioxidant activity, such as radical scavenging and metal ion chelation abilities. Previous studies showed that hydroxyl group in 4′ position is not the sole determinant for antioxidant activity, but also the 3- and 5-OH groups. The study of antioxidant effect against hydroxyl (•OH) and hydroperoxyl (•OOH) radicals in aqueous simulated media using density functional quantum chemistry and computational kinetics methods revealed that trans-resveratrol may act as an efficient •OOH, and also presumably •OOR, radical scavenger.. Resveratrol can also be used in minimizing or preventing lipid oxidation in pharmaceutical products, delaying toxic oxidation products formation, and maintaining both nutritional quality and prolonging pharmaceuticals shelf-life. In addition, resveratrol’s antioxidant properties have been successfully employed to protect cells against hydrogen peroxide-induced oxidative stress, where the pre-treatment with resveratrol promoted cell survival and protection against UV-irradiation-induced cell death. Resveratrol cellular defense could be achieved, at least in part, by its ability to act as a direct antioxidant and an indirect cellular antioxidant system inducer through modulation of several cellular antioxidant pathways, thereby balancing cellular redox status.
As already highlighted, resveratrol is a powerful antioxidant that beneficial effect is hampered by its low bioavailability. Many attempts have been made to generate resveratrol derivatives by esterification process to improve their lipophilicity and application in lipid-based foods and biological environments. About 12 different esterified acyl chlorides have been synthesized including butyryl chloride, caproyl chloride, capryloyl chloride, capryl chloride, docosahexaenoyl chloride, eicosapentaenoyl chloride, lauroyl chloride, myristoyl chloride, oleoyl chloride, palmitoyl chloride, propionyl chloride, and stearoyl chloride. These derivatives were able to effectively inhibit copper ion-induced low-density lipoprotein (LDL) oxidation and inhibited hydroxyl radical-induced DNA scission. These results clearly demonstrated that resveratrol derivatives might serve as potential antioxidants in foods and biological systems.
