  • Amphiphilic block copolymer and preparation method thereof and micellar drug-loading system formed by same with antitumor drug
    Patent number: 9393312
    Abstract: The present invention relates to a novel amphiphilic block copolymer and the preparation method thereof, as well as a micellar drug-loaded system formed by said copolymer and an anti-tumor drug. Said amphiphilic block copolymer comprises a hydrophilic segment and a hydrophobic segment, and the end group of said hydrophobic segment is end-capped with a hydrophobic group. Methoxypolyethylene glycol (or polyethylene glycol)-polyester block copolymer which has recognized safety is used as a fundamental material of the amphiphilic block copolymer of the present invention, and the terminal hydroxyl group of the polyester segment is modified with a hydrophobic group, whereby the compatibility between the drug molecule and the hydrophobic segments of the block copolymer is improved, and the interaction therebetween is enhanced. Moreover, a larger space for accommodating the drug molecules is provided.
