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.
