Abstract:
Objective:To study the preparation methods of N3-O-toluyl-flulorouracil (TFu) solid lipid nanoparticles(SLNs) and chitosan modified TFu SLNs. Methods: TFu-SLNs and chitosan modified TFu-SLNs were prepared by film dispersion-homogenization methods. The morphology, particle diameter and zeta potential were detected. The preparation methods were optimized by single factor experiments and an orthogonal design, and the stability of the nanoparticles was also studied. Results: The mean diameter of TFu-SLNs was 160. 2nm, and the zeta potential was -33. 2 mV. The mean diameter of chitosan modified TFu- SLNs was 400. 3nm, and the zeta potential was +12. 87 mV. With the concentration increase of chitosan, the zeta potential was enhanced. The optimized TFu-SLNs had higher reproducibility and stability. Conclusion:The formula of TFu-SLNs is optimized by an orthogonal design to obtain the optimal formula of TFu -SLNs and chitosan modified TFu-SLNs.
