The present study was undertaken to develop a Curcumin nanoparticle system with chitosan as a hydrophilic carrier. In addition, the anti-diabetic potential of curcumin loaded chitosan nanoparticles were assessed in comparison to those of free curcumin by examining the anti-hyperglycemic efficacy using in vitro assays.Curcumin loaded chitosan nanoparticles were prepared and characterized for particle size by transmission electron microscopy, FT-IR, differential scanning calorimetry and therapeutic effects of curcumin loaded chitosan nanoparticles were evaluated by measuring the level of GLUT-4 present at the plasma membrane in L6myc myotubes followed by western blotting. Additionally, anti-inflammatory potential of curcumin loaded chitosan nanoparticles were assessed by enzyme immunoassay using appropriate ELISA kits.Transmission electron microscopy revealed an average nanocurcumin particle size of 74 nm. Under in vitro conditions, treatment with chitosan-nanocurcumin (CS-NC) caused a substantial increase in the GLUT-4 translocation to the cell surface in L6 skeletal muscle cells and the effect was associated with increased phosphorylation of AKT (Ser-473) and its downstream target GSK-3β (Ser-9).The therapeutic potential of nanocurcumin is prominent than that of curcumin alone. Nanocurcumin could improve the solubility of curcumin and may prolong its retention in the systemic circulation.
