  • BRIDGED POLYETHYLENE GLYCOL-ALIPHATIC POLYESTER BLOCK COPOLYMER, PREPARATION METHOD FOR SAME, INTERMEDIATE OF SAME, AND USES THEREOF
    Publication number: 20190060463
    Abstract: This invention relates to a bridged polyethylene glycol-aliphatic polyester block copolymer, which can be used in the production of delivery carriers for micromolecular chemotherapeutic drugs and nucleic acid drugs. Nanoscale pharmaceutical carriers produced from the bridged block polymer may be subjected to specific degradation under pH environments in tumor tissues or tumor cells so as to change the structure of nanoparticles, enhance cell uptake or intracellular drug release, and improve the sensitivity of tumor cells to drugs.
