New chemotherapeutic agents with novel mechanisms of action are urgently required to combat the challenge imposed by the emergence of drug-resistant mycobacteria. In this study, a phenotypic whole-cell screen identified 5-nitro-1,10-phenanthroline (5NP) as a lead compound. 5NP-resistant isolates harbored mutations that were mapped to and were also resistant to the bicyclic nitroimidazole PA-824.

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 with the promising anti-invasive activity of colon cancer cells overexpressing TMPRSS4.
