QPD is an autosomal dominant bleeding disorder due to a gain-of-function defect in fibrinolysis. Although affected individuals do not exhibit systemic fibrinolysis, they show delayed onset bleeding after challenge, such as surgery. The hallmark of the disorder is markedly increased PLAU levels within platelets, which causes intraplatelet plasmin generation and secondary degradation of alpha-granule proteins. Function [UROK_HUMAN] Specifically cleaves the zymogen plasminogen to form the active enzyme plasmin. Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMed Fragment-based lead discovery has been applied to urokinase-type plasminogen activator (uPA). The (R)-enantiomer of the orally active drug mexiletine 5 (a fragment hit from X-ray crystallographic screening) was the chemical starting point. Structure-aided design led to elaborated inhibitors that retained the key interactions of (R)-5 while gaining extra potency by simultaneously occupying neighboring regions of the active site. Subsequent optimization led to 15, a potent, selective, and orally bioavailable inhibitor of uPA.
