UK-371804 是一种尿嘧啶型纤溶酶原激活物的抑制剂，Ki=10 nM。

GW-6604 是一种 ALK5 抑制剂，具有明显的抗纤维化作用，可改善肝功能。

TM5007 是纤溶酶原激活物抑制剂-1（PAI-1；IC50 为 29 uM）的强效抑制剂。

Nattokinase is a serine protease derived from nattō, exhibiting oral bioavailability and fibrinolytic/anticoagulant properties. It degrades fibrin, fibrinolytic substrates, and PAI-1 to dissolve thrombi while inhibiting platelet aggregation, making it suitable for cardiovascular disease and Alzheimer's disease research.

UK-371804 is a potent and selective urokinase-type plasmogen activator (uPA) inhibitor with excellent enzyme potency (Ki=10 nM) and selectivity profile (2700-fold versus plasmin and 4000-fold versus tPA).
