摘要: NAMI-A has showed extraordinary activities against metastatic tumors. However, the hydrolysis of DMSO from NAMI-A could reduce anti-metastatic activity. To enhance the circulation time and the anti-metastatic effect of NAMI-A, we first synthesized the NAMI-A-loaded nanoparticles. NAMI-A-loaded nanoparticles were prepared by the double emulsion method and characterized by scanning electron microscopy for surface morphology, laser light scattering for size and zeta potential for surface charge. Controlled release of NAMI-A was observed in a sustained manner. Compared with free NAMI-A, NAMI-A -loaded nanoparticles exhibited superior antitumor effect by delaying tumor growth in T739 mice. PLGA-mPEG nanoparticles are promising for further studies as drug delivery carriers.
