Mycobacterium tuberculosis (MTb) possesses two non-proton pumping type II NADH dehydrogenase (NDH-2) enzymes which are predicted to be jointly essential for respiratory metabolism.. Furthermore, the structure of a closely related bacterial NDH-2 has been reported recently, allowing for the structure-based design of small-molecule inhibitors. Herein, we disclose MTb whole-cell structure-activity relationships (SAR) for a series of 2-mercapto-quinazolinones which target the ndh encoded NDH-2 with nanomolar potencies...
