Using an NMR-based screen, a novel class of urokinase inhibitors were identified that contain a 2-aminobenzimidazole moiety. The inhibitory potency of this family of inhibitors is similar to that of inhibitors containing a guanidine or amidine group. However, unlike previously described guanidino- or amidino-based inhibitors which have pK(a) values greater than 9.0, urokinase inhibitors containing a 2-aminobenzimidazole have pK(a) values of 7.5. Thus, 2-aminobenzimidazoles may have improved pharmacokinetic properties which could increase the bioavailability of inhibitors which contain this moiety. A crystal structure of one of the lead inhibitors, 2-amino-5-hydroxybenzimidazole, complexed with urokinase reveals the electrostatic and hydrophobic interactions that stabilize complex formation and suggests nearby subsites that may be accessed to increase the potency of this new series of urokinase inhibitors.

Disease

UROK_HUMAN Defects in PLAU are the cause of Quebec platelet disorder (QPD) [MIM:601709. 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.[1]

Function

UROK_HUMAN Specifically cleaves the zymogen plasminogen to form the active enzyme plasmin.

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
