  • Patent number: 10307505
    Abstract: A wound dressing material for controlled activation of a wound healing therapeutic compound in the presence of a protease enzyme in a wound fluid, the material comprising: a medically acceptable polymer; a wound healing therapeutic agent; an inhibitor of the protease enzyme; and a linker group which is cleavable by the protease enzyme wherein the activities of both the wound healing therapeutic agent and the inhibitor increased by contacting the wound dressing material with a would fluid containing the protease enzyme. For example, the enzyme may be a matrix metalloproteinase, the therapeutic agent may be a reactive oxygen scavenger, and the inhibitor may be a tissue inhibitor of metalloproteinase (TIMP).
    Type: Grant
