摘要: Y-Shaped amphiphilic copolymers (zwitterionic-(PLLA2.5K)2 and MPEG-(PDLA2.5K)2) were simply synthesized through click reaction of alkyne-(PLA2.5K)2 zwittterionic-N3 or MPEG-N3. Gel permeation chromatography (GPC) 1H nuclear magnetic resonance (1H NMR) employed to characterize the composition structure these copolymers. The stereocomplexes prepared from pairs zwitterionic-(PLLA2.5K)2/MPEG-(PDLA2.5K)2 (molar ratio = 1 : 1), confirmed by differential scanning calorimeter (DSC). Furthermore aggregation behaviors for polymers their had been proved fluorescence spectroscopy (PL), transmission electron microscopy (TEM), dynamic light scattering (DLS) static (SLS), zeta potential. Their critical micelle concentration (CMC) obtained PL was 0.0213 mg mL−1 zwitterionic-(PLLA2.5K)2/MPEG1.9K-(PDLA2.5K)2 0.1265 zwitterionic-(PLLA2.5K)2/MPEG5K-(PDLA2.5K)2. could self-assemble into spherical micelles with diameters 76 nm (zwitterionic-(PLLA2.5K)2/MPEG1.9K-(PDLA2.5K)2) 89 (zwitterionic-(PLLA2.5K)2/MPEG5K-(PDLA2.5K)2) respectively. biocompatibility evaluated relatively low cytotoxicity. DOX-loaded a higher drug loading content encapsulation efficiency, release DOX in controlled manner. Therefore, new stereocomplex zwitterionic-(PLLA)2/MPEG-(PDLA)2 has great potential as hydrophobic nanocarrier.
