In Vitro	PAI-749 is a potent and selective synthetic antagonist of plasminogen activator inhibitor 1 (PAI-1) that preserved tissue-type plasminogen activator (tPA) and urokinase-type plasminogen activator (uPA) activities in the presence of PAI-1 (IC50 values, 157 and 87 nM, respectively)[2]. PAI-749 quenches the fluorescence (Fl) of fluorophore-tagged PAI-1 (PAI-NBD119) with the apparent Kd of 254 nM) and the IC50 of 140 nM[2].
