Curcumin is widely known for its antibacterial, antioxidant and anti inflammatory effects and has been reported to possess anticancerous activity as well. However, its medical application is limited because of poor bioavailability and rapid metabolism. In this study, we encapsulated curcumin in solid lipid nanoparticles and studied its anticancerous effect in Dalton’s Ascites Lymphoma (DAL) mice model. The physicochemical characteristics of curcumin solid lipid nanoparticles (CUR-SLN) were assessed and the anticancer efficacy was determined by in vivo studies. The curcumin solid lipid nanoparticles were synthesized by solvent emulsification evaporation method with particle size less than 100 nm. Antitumor effect of nanocurcumin (50 mg/kg) and curcumin (100 mg/kg) was evaluated in Dalton’s Ascites Lymphoma bearing mice. Pathological and immunohistochemical parameters were studied. Mean survival time and percentage increase in lifespan were assessed. Nanocurcumin group showed more significant influence in reducing tumor volume and weight, inducing apoptosis, reducing angiogenesis and invasion restoring antioxidant parameters and increased mean survival time. Curcumin and nanocurcumin inhibited the activation of nuclear factor-kappa B (Nf-kB), and thereby proved the pathway by which it induced anti-angiogenic and anti-invasive property.
