  • Patent number: 8535681
    Abstract: A drug composition comprising a charged moiety coupled to a therapeutic compound is disclosed. The charged moiety is configured to interact with at least one type of component of opposite charge in a biological tissue to create an in situ depot for prolonged drug delivery. The biological tissue may be eye tissue or any tissue containing charged components. Further, a method of treating the human body is disclosed. The method is for introducing into a human body a drug composition comprising a charged moiety coupled to a therapeutic compound. Introduction may be through injection. A method of manufacturing a drug composition comprising a charged moiety coupled to a therapeutic compound is also disclosed.

  • Patent number: 5851989
    Abstract: The invention provides a method for extending the plasma half-life of heparin-binding proteins by coadministering such proteins with a therapeutically acceptable compound capable of inhibiting their binding to a low affinity heparin-like binding site on the surface of cells. In one embodiment of the invention, the heparin-binding protein is a growth factor or selectin. The binding inhibitory compound can, for example, be a purified native heparin preparation, a heparin fragment, or another polyanionic compound, such as dextran sulfate, heparan sulfate, pentosan sulfate, or hyaluronate.

  • Patent number: 5464815
    Abstract: The invention provides a method for extending the plasma half-life of heparin-binding proteins by coadministering such proteins with a therapeutically acceptable compound capable of inhibiting their binding to a low affinity heparin-like binding site on the surface of cells. In one embodiment of the invention, the-heparin-binding protein is a selectin. The binding inhibitory compound can, for example, be a purified native heparin preparation, a heparin fragment, or another polyanionic compound, such as dextran sulfate, heparan sulfate, pentosan sulfate, or hyaluronate.
