摘要: 目的 研究甘草酸表面修饰阿霉素壳聚糖纳米粒(G L-ADM-NPs)在小鼠体内的分布。方法 GL- ADM-NPs 经小鼠尾静脉给药, 采用液质联用(LC/MS/MS)法检测阿霉素在小鼠血浆、心、肝、脾、肺、肾中的浓度随时间的变化, 并与游离阿霉素溶液(F-ADM)组和阿霉素壳聚糖纳米粒(ADM-NPs)组进行比较。以相对摄取率(Re)和峰浓度比(Ce)为指标评价其靶向性。结果 与F-ADM 相比,ADM-NPs 明显提高药物在肝脏中的浓度(Re和Ce分别为3 .54 和2 .2);经甘草酸修饰后GL-ADM-NPs 对肝脏的靶向作用更强,Re和Ce分别达到5 .83 和3 .42, 在心和肾中药物分布显著降低, AUC 分别为F-ADM 的43 .06 %和62 .58 %。结论 GL-ADM-NPs 改变了药物ADM 的体内分布特征, 具有明显的肝靶向性, 并能显著降低心和肾毒性, 有望成为肝癌治疗药物ADM 的理想输送载体。

Abstract: AIM: To study the distribution characteristics and liver targeting trend of adriamycin-loaded chitosan nanoparticles surfacemodified with glycyrrhizin (GL-ADM-NPs) in mice.METHODS: The GL-ADM-NPs, adriamy cin-loaded chitosan nanoparticles (ADMNPs), and free adriamycin solution (F-ADM) were intravenously administered to mice, respectively.The LC/MS/MS method was used to determine the concentrations of Adriamycin in mice plasma, heart, liver, spleen, lung and kidney. The targeting efficiency was evaluated by targeting parameters (Re and Ce).RESULTS: Compared with F-ADM, ADM-NPs obviously increased the adriamycin concentration in the liver, Re and Ce were 3.54 and 2.2, respectively. After modified with glycyrrhizin on the nanoparticle surface, G L-ADM-NPs showed a higher targeting efficiency in the liver.The Re and Ce were 5.83 and 3.42, respectively.The levels of GL-ADM-N Ps in the heart and kidney tissues were sig nificantly decreased. The AUC were 43.06 % and 62.58 % of the values of F-ADM. CONCLUSION: GL-ADM-NPs changes the tissue distribution of ADM, has the liver targeting effect, and might decrease the side effects of ADM.It will be a promising carrier to deliver ADM to liver.
