TMPRSS4 is a novel type II transmembrane serine protease that has been implicated in the invasion and metastasis of colon cancer cells. In this study, a novel series of 2- hydroxydiarylamide derivatives were synthesized and evaluated for inhibiting TMPRSS4 serine protease activity and suppressing cancer cell invasion. These derivatives demonstrated good inhibitory activity against TMPRSS4 serine protease, which correlated ...
