Aminofutalosine synthase (MqnE) catalyzes an important rearrangement reaction in menaquinone biosynthesis by the futalosine pathway. In this Letter, we report the identification of previously unreported inhibitors of MqnE using a mechanism-guided approach. The best inhibitor shows efficient inhibitory activity against H. pylori (IC50 = 1.8 +/- 0.4 mu M) and identifies MqnE as a promising target for antibiotic development.
