Abstract

Mangiferin is a promising effective chemopreventive agent against various tumors. However, its clinical use is limited by poor water solubility and low bioavailability. In this article, mangiferin loaded magnetic PCEC microspheres (MG-MS) were designed, characterized and the antitumor activity of MG-MS was evaluated in vitro. The magnetic nanoparticles (MNP) were synthesized via the high-temperature reaction of iron acetylacetonate in phenyl ether in the presence of oleic acid and oleylamine. Poly (ε-caprolactone)-poly (ethyleneglycol)-poly (ε-caprolactone) (PCL-PEG-PCL, PCEC) copolymers were formed by ring-opening copolymerization of ε-CL initiated by PEG-diol using Sn(Oct)2 as a catalyst and MG-MS were prepared by solvent diffusion method. MNP, PCEC copolymer, and MG-MS were characterized by GPC, TEM, XRD, FT-IR, 1H-NMP and Malvern Laser Particle Sizer. Meanwhile, the antiproliferative activity in vitro and in vitro release behavior of this microspheres were studied in detail. The results indicate that the obtained magnetic microspheres might have great potential as an effective carrier for mangiferin used in cancer chemotherapy.
