Curcumin, a natural chemical compound found in Curcuma longa, has been applied in multiple medicinal areas from antibiotic to antitumor treatment. However, the chemical structure of curcumin results in poor stability, low solubility, and rapid degradation in vivo, hindering its clinical utilization. To address these issues, we have developed a novel niosome system composed of nonionic surfactants: Span 80, Tween 80, and Poloxamer 188. Curcumin was encapsulated in the niosomes with a high entrapment efficiency of 92.3 +/- 0.4%. This system provided controlled release of curcumin, thereby improving its therapeutic capability. Dynamic dialysis was conducted to evaluate the in vitro drug release of curcumin-niosomes. Curcumin-niosomes exhibited enhanced cytotoxic activity and apoptotic rate against ovarian cancer A2780 cells compared with freely dispersed curcumin. These results demonstrate that the curcumin-niosome system is a promising strategy for the delivery of curcumin and ovarian cancer therapy.
