摘要:

肺纤维化是一种致命性肺部疾病, 目前临床常规的甲强龙(MPS)联合环磷酰胺(CTX)治疗方法存在明显的不良反应. 基于降低药物毒副作用的目的, 本文设计了一种聚多巴胺(PDA)包覆的Fe3O4纳米粒子/甲强龙/环磷酰胺复合超粒子(Fe3O4/MPS/CTX@PDA SPs), 提出磁性靶向治疗肺纤维化的思路. 从预制的油溶性Fe3O4纳米粒子出发, 通过水包油微乳液模板法制备了Fe3O4 超粒子(SPs), 并在进一步包覆PDA壳层的过程中引入MPS和CTX, 制备了Fe3O4/MPS/CTX@PDA SPs, 考察了Fe3O4/MPS/CTX@PDA SPs的稳定性、 磁性、 对MPS和CTX的负载及释放, 分析了其生物毒性, 并建立动物模型验证了其磁性靶向功能.

Abstract:

Pulmonary fibrosis is a serious fatal disease and it exists clinical adverse effects for the conventional combined treatment using methylprednisolone(MPS) and cyclophosphamide(CTX). In this work, polydopamine(PDA)-coated Fe3O4/MPS/CTX superparticles(Fe3O4/MPS/CTX@PDA SPs) were prepared to reduce the adverse effects of drugs, which provide a magnetic targeting strategy for the therapy of pulmonary fibrosis. In the experiment, Fe3O4 SPs were foremost prepared from Fe3O4 nanoparticles using oil-in-water droplets as the templates, and followed by coating PDA shell in the presence of MPS and CTX to produce Fe3O4/MPS/CTX@PDA SPs. Systematically characterizations proved the successful preparation of Fe3O4/MPS/CTX@PDA SPs, and revealed the stability, magnetism, drug loading and release. The cytotoxicity was further discussed in vitro, and an animal model was built to confirm the magnetic targeting of Fe3O4/MPS/CTX@PDA SPs in vivo.
