Description: UK-371804 is a potent and selective uPA inhibitor with excellent enzyme potency (Ki 10 nM) and selectivity profile (4000-fold versus tPA and 2700-fold versus plasmin). In vitro, UK-371804 is able to inhibit exogenous uPA in human chronic wound fluid (IC50=0.89 microM). In vivo, in a porcine acute excisional wound model, following topical delivery, UK-371804 is able to penetrate into pig wounds and inhibit exogenous uPA activity with no adverse effect on wound healing parameters. UK-371804 was selected as a candidate for further preclinical evaluation for the treatment of chronic dermal ulcers.
