  • Patent number: 11911406
    Abstract: Provided herein are polymer-drug conjugates with enhanced antibacterial efficacy. These conjugates include a polymer comprising a plurality of masked cationic functional groups and an antibiotic drug linked to the cationic polymer by a pH-sensitive linker. The masked cationic functional groups may be converted in aqueous solution to free cationic functional groups faster at a pH below 7 than a pH above 7. The cationic functional groups may be masked as either an uncharged functional group or by an ion pair with a neighboring anionic functional group attached to the polymer. The pH-sensitive linker releases the drug faster in aqueous solution at or below a pre-determined pH value selected from a range of 4.5 to 7 than a pH value above 7.

  • Patent number: 11883406
    Abstract: The present invention relates to a method for producing an alginic acid-folic acid conjugate, an alginic acid-folic acid conjugate produced thereby, and a pharmaceutical composition containing the same. According to the method of producing an alginic acid-folic acid conjugate using a carboxy-protecting group and a leaving group, the hydroxyl group of alginic acid forms an ester group with the carboxyl group of folic acid. Thus, the alginic acid-folic acid conjugate may clearly distinguish cancer cells from normal tissue by more effectively targeting cancer cells than a conventional alginic acid-conjugated folic acid in which the amine group of folic acid is covalently bonded to the carboxyl group of alginic acid. Accordingly, the alginic acid-folic acid conjugate may be effectively used for precise diagnosis and efficient surgical resection of cancer lesions.

  • Patent number: 11859023
    Abstract: Disclosed herein is method for conjugating a metal chelating agent to a functionalized dextran by reacting a chelator with an aminated dextran backbone, where the chelator comprises a one, and only one, derivatized carboxylic acid group to form a chelator-dextran complex. In certain aspects, the dextran-chelator complex is substantially free of intra- or intermolecular crosslinking. In certain aspects, the functionalized dextran is an amine dextran, an alkynyl dextran, or a thiol dextran. In exemplary implementations, the functionalized dextran is an amine dextran. In further embodiments, one and only one carboxylic acid group on the chelating agent is derivatized as a N-hydroxysuccinimide (NHS) ester.
