目的 制备具有脑靶向的冰片(BO)修饰多柔比星(DOX)/丹参酮ⅡA磺酸钠(STS)双载药纳米粒(BO-DOX/STS-NPs)并对其理化性质进行考察.方法 采用复乳溶剂挥发法制备BO-DOX/STS-NPs,正交设计后以包封率和载药量为评价指标优化处方工艺.结果 制备BO-DOX/STS-NPs的优化条件:药物与PEG2000-PLA的质量比为1∶20,外水相PVA的体积浓度为3％,内水相与有机相体积比为1∶10,有机相与外水相体积比为1∶10.按优化条件所制备的BO-DOX/STS-NPs粒径为(114.75±1.39)nm,Zeta 电位为(-6.58±0.02)mV,DOX 与 STS 的包封率分别为(97.34±0.97)％和(98.21±0.73)％,载药量分别为(2.40±0.03)％和(1.18±0.01)％,药物释放曲线均符合Ritger-Peppas方程模型.结论 采用复乳溶剂挥发法成功制备了 BO-DOX/STS-NPs,确定了最优制备处方和制备工艺.所制备的纳米粒粒径分布均一、稳定性好、载药量高,具有缓释效果.
Preparation and characterization of doxorubicin-sodium tanshinoneⅡA sulfonate-loaded modifying borneol cationic nanoparticles
AIM To prepare Doxorubicin-Sodium tanshinone Ⅱ A sulfonate-loaded modifying borneol cationic nanoparticles(BO-DOX/STS-NPs)with brain targeting property.METHODS The BO-DOX/STS-NPs were prepared with the double emulsion solvent evaporation method and were optimized through the orthogonal test according to entrapped efficiency and drug loading of BO-DOX/STS-NPs.RESULTS The optimal conditions for preparation of BO-DOX/STS-NPs were as follows:the mass ratio of drug to PEG2000-PLA was 1∶20,the volume concentration of PVA in the external aqueous phase was 3％,the volume ratio of internal water phase to oil phase was 1∶10,and the volume ratio of oil phase to outer water phase was 1∶10.The mean particle size of the resulted BO-DOX/STS-NPs was(114.75±1.39)nm and Zeta potential was(-6.58±0.02)mV.The average entrapped efficiency was(97.34±0.97)％for DOX and(98.21±0.73)％for STS.The drug-loading capacity was(2.40±0.03)％for DOX and(1.18±0.01)％for STS.The drug release curves for both drugs conformed to the Ritger-Peppas equation model.CONCLUSION An optimized nanoparticle drug delivery system is obtained by the double emulsion method.The optimized nanoparticles have uniform particle size distribution,good stability,high drug loading and sustained release effect.
