Endostatin-Encapsulated N-Succinyl-Chitosan Nanoparticles Inhabited the Growth of MCF-7 Cell

摘要

A simple method was developed to synthesize the N-succinyl-chitosan (NSC) successfully. NSC was characterized by FTIR, 1 ) H NMR and element analysis. The NSC can form nanoparticles with TPP through electrostatic interaction. The morphology, particle size and zeta potential of the nanoparticle were investigated and showed a 100 - 200 nm in diameter with a positive potential 9.99 mv. The encapsulation efficiency of NSC-ES-NPs was 94.76 ± 0.05. The in vitro cell culture indicates that NSC has non-toxicity and cell-compatibility. NSC-ES-NPs show antitumor activity against MCF-7 cell. Our results demonstrate that NSC has great potential in the drug controlled release delivery.
