  • Publication number: 20160206750
    Abstract: Described herein are block copolymers, and methods of making and utilizing such copolymers. The described block copolymers are disruptive of a cellular membrane, including an extracellular membrane, an intracellular membrane, a vesicle, an organelle, an endosome, a liposome, or a red blood cell. Preferably, in certain instances, the block copolymer disrupts the membrane and enters the intracellular environment. In specific examples, the block copolymer is endosomolytic and capable of delivering an oligonucleotide (e.g., an mRNA) to a cell. Compositions comprising a block copolymer and an oligonucleotide (e.g., an mRNA) are also disclosed.

  • Publication number: 20140235790
    Abstract: Provided herein are compositions and methods for intracellular delivery. The compositions are polymer compositions in which the polymer serves as a carrier for therapeutic and/or diagnostic agents. The polymer compositions are effective in targeted delivery of therapeutic and/or diagnostic agents to a cell. The polymer compositions include a targeting moiety that includes carbohydrate groups that effectively target specific cell surface receptors. The polymer compositions also include an agent binding moiety that effectively associates the therapeutic and/or diagnostic agent to be delivered to the cell.

  • Publication number: 20100029545
    Abstract: Polymeric nanoaggregate drug-delivery compositions including boron-containing copolymers are described. The drug-delivery compositions may further include a therapeutic agent comprising a nucleic acid, a polynucletide, a peptide, a polypeptide, a protein, a pharmaceutical or any combinations thereof. Methods for making the polymeric nanoaggregate compositions including at least one therapeutic agent (for example, insulin) as well as methods for administration of these compositions to mammals are also set forth. The disclosure also describes compositions and methods for controlled drug delivery. Further, polymeric nanoaggregate boron-containing compositions including insulin and methods for monitoring and regulating blood glucose levels of a mammal are also described. The disclosure also describes methods for treatment and/or control of diabetes mellitus by administering polymeric nanoaggregate boron-containing compositions including insulin to a mammal in need.
