WGU55

WGU55 is a selective and potent reversible type II transmembrane serine protease TMPRSS6 inhibitor with a Ki value of 12.15 nM. In KEK293 cells, WGU55 inhibits TMPRSS6 activity with an IC50 value of 138 nM. It displays a Ki value of 3510 nM for the homologous protease matriptase (SI=289) and a Ki value of 5.2 μM for the key coagulation protease factor Xa. WGU55 is applicable in the study of iron overload-related diseases, such as hereditary hemochromatosis.
