摘要:

本研究制备紫杉醇(paclitaxel,PTX)与白藜芦醇(resveratrol,Rev)共载阳离子纳米制剂,用于逆转肿瘤多药耐药性。采用薄膜分散法制备载药阳离子纳米制剂;通过Box-Behnken响应面法对PTX及Rev共载阳离子纳米制剂处方进行优化;利用透析法对体外释放行为进行考察;通过MTT法对其逆转多药耐药性进行研究。优化后的PTX及Rev共载阳离子纳米制剂包封率分别达98.93%、81.23%,具有较高的包封率,适用于药物PTX及Rev共递送;平均粒径为186.33 nm,Zeta电位6.38 mV,具有良好的粒径及电位;载药纳米制剂具有明显的缓释药物行为;体外细胞毒性研究发现逆转耐药指数达9.05,具有明显的逆转耐药性。制备的PTX与Rev共载阳离子纳米制剂有效共载药物,达到理想的逆转多药耐药效果。

Abstract:

In order to construct cationic nanocarrier with paclitaxel (PTX) and resveratrol (Rev) co-loaded for reversing multidrug resistance activity.The cationic nanocarrier was prepared by the thin-film dispersion method;The prescription of cationic nanocarrier with PTX and Rev co-loaded was optimized by Box-Behnken response surface method;In vitro drug release study was conducted using dialysis method;The reversing multidrug resistance activity was evaluated by the standard MTT assay.The encapsulation efficiency of PTX and Rev in cationic nanocarrier were 98.93% and 81.23%,respectively;The average particle size was 186.33 nm,and the zeta potential was 6.38 mV;The drug-loaded nanocarrier exhibited significant slow-release drug behavior in vitro;The cytotoxicity studies demonstrated that cationic nanocarrier had high cellular inhibition in drug-resistant cells,the reversal of resistance index was 9.05.The cationic nanocarrier with optimal prescription was suitable for the co-delivery of PTX and Rev,achieved excellent reversing multidrug resistance efficacy.

Key words: paclitaxel, resveratrol, reversing multidrug resistance, Box-Behnken response surface method, cationic nanocarrier
