UKI-1

UKI-1 (WX-UK1) is a potent urokinase-type plasminogen activator (uPA) inhibitor with a K i of 0.41 μM. UKI-1 is also a low molecular weight serine protease inhibitor. UKI-1 is a potent antimetastatic agent and inhibits the invasive capacity of carcinoma cells In Vitro UKI-1 (WX-UK1; 0.1-1.0 μg/mL) treatment shows a decrease of tumor cell invasion by up to 50% is achieved in both models with the SCCHN line FaDu and the cervical carcinoma line HeLa. UKI-1 (WX-UK1) interferes with the plasminogen activation system at 2 levels: it inhibits plasmin formation directly and via inhibition of uPA. In vitro invasion models with highly invasive fibrosarcoma and breast cancer cells showed that UKI-1 effectively inhibits migration of the cells through fibrin matrices.

In Vivo UKI-1 (WX-UK1) treatment has antimetastatic activities that significantly reduces the number of metastatic lesions and tumor growth in metastasizing rat pancreatic and mammary adenocarcinoma tumor models .
