Topical Nanostructured Lipid Carriers of Alpha-mangostin and Resveratrol for Synergistic Antioxidant Activity

Abstract

Background: Nanostructured lipid carriers (NLCs) are interesting lipid-based carrier systems for enhancing the penetration of drugs through the skin after topical administration. Objective: Dual drug-loaded NLCs of alpha-mangostin (M) and resveratrol (R) to enhance antioxidant activity were developed for topical delivery. Methods: The efficacy of a combination of M and R was evaluated in terms of the antioxidant activity. M and R were loaded into the NLCs using a high shear homogenization and ultrasonication process. The particle size, zeta potential, and physical properties of the NLCs were observed. The M and R loading efficiency as well as release patterns were examined using Franz diffusion cells. Moreover, the antioxidant efficacy and in vitro cytotoxicity in the normal human fibroblast (NHF) of the NLCs were evaluated as well. Results: The efficacy of a combination of M and R was evaluated in terms of the antioxidant activity. M and R were loaded into the NLCs using a high shear homogenization and ultrasonication process. The particle size, zeta potential, and physical properties of the NLCs were observed. The M and R loading efficiency, as well as release patterns, were examined using Franz diffusion cells. Moreover, the antioxidant efficacy and in vitro cytotoxicity in the normal human fibroblast (NHF) of the NLCs were evaluated as well. Conclusion: The M and R loaded NLCs were attractive systems for the synergistic antioxidant activity for topical application.
