- W4385836948 abstract "Objective: The present study aimed to fabricate Poly lactic acid co-glycolic acid (PLGA) nanoparticles loaded with resveratrol using a novel graft co-polymer surfactant named Soluplus®. Methods: The PLGA nanoparticles were prepared in the present study using polyvinyl caprolactam polyvinyl acetate polyethylene glycol amphiphilic graft copolymer named Soluplus® as surfactant through double emulsification and single emulsification-solvent evaporation method. The formulations were prepared successfully to encapsulate the drug resveratrol, and then evaluated for their particle size, polydispersity index, zeta potential, drug loading and the degree of entrapment of the drug. A scanning electron microscope was used to examine the morphology of the nanoparticles. In vitro drug release was assessed and, mathematical pharmacokinetic modelling was done to assess the release pattern. A comparative cytotoxicity study between free drug and prepared nanoparticles using MTT assay was carried out for cell viability evaluation. Uptake and internalization of nanoparticles were also studied using confocal fluorescence microscopy. Results: The results demonstrated successful fabrication of the PLGA nanoparticles using the Soluplus as polymer surfactant. The drug, polymer and the all the excipients were found to be compatible and did not indicate any interaction. The results also indicated the prepared nanoparticles (SF2) as suitable resveratrol delivery vehicle in terms of the compliant particle size (344.6 ±6.63 nm), polydispersity index (0.962), zeta potential (- 18.5±1.21), drug loading (18.94± 0.27%), the entrapment efficiency (39.62±0.17%) and drug release (75.13±0.17%). The shape and surface morphology of the formulated nanoparticles were found to be spherical and smooth. Cytotoxicity study also demonstrated significant reduction of cell viability by the nanoparticle compared to free resveratrol. The highest cytotoxicity of SF2 against MCF7 cell was found in 2000 nM concentration with 3.03±0.05 percent of cell viability. It was found that the percentage of growth inhibition was increasing with increasing concentration of SF2 and IC50 value of this assay was 108.94 μg/ml. Conclusion: It has been found that the Resveratrol loaded PLGA nanoparticles were successfully formulated and found to perform better in terms of efficacy and cytotoxicity." @default.
