摘要:
为提高抗生素在病灶感染处的渗透与富集能力,减少单一抗生素在临床上的使用剂量,进一步降低细菌耐药性的风险,采用化学偶联法合成聚乳酸羟基乙酸透明质酸的两亲性嵌段共聚物用于封装抗生素。该共聚物在水中可自组装为内部疏水、外部亲水的胶束(Micelles, MS),以透析法将疏水药物环丙沙星(Ciprofloxacin, CIP)和利福平(Rifampicin, RFP)封装在MS中,构建了CIP@MS的单一载药胶束及CIP/RFP@MS的双载药胶束;对合成物质的结构、形貌、临界胶束浓度以及载药率进行测试与表征,将MS、CIP@MSCIP/RFP@MS与金黄色葡萄球菌(Staphylococcus aureus, S.aureus)和大肠埃希菌(Escherichia coli, E.coli)共培养以探索载药胶束的体外抗菌作用,与人脐静脉内皮细胞共培养以评估载药胶束的体外细胞毒性。结果表明:聚乳酸羟基乙酸透明质酸聚合物在水中可自组装约为142 nm大小的球形胶束,载药后粒径增大约为194 nm;CIP在CIP@MS中的载药率为1.42%,CIP和RFP在CIP/RFP@MS中的载药率分别为1.09%和1.41%;CIP@MS对S.aureus和E.coli的抗菌率分别为27.7%和99.9%,CIP/RFP@MS对S.aureus和E.coli的抗菌率分别达到85.4%和100.0%。该研究为双载药胶束的制备方法及抗菌方面的应用提供了一定的实验基础和理论依据。
