A high-throughput screen led to the discovery of 2-amino-4-oxo-4-phenylbutanoate inhibitors of the 1, 4-dihydroxy-2-naphthoyl-CoA synthase (MenB) from the menaquinone biosynthesis pathway in Mycobacterium tuberculosis. However, these compounds are unstable in solution and eliminate to form the corresponding 4-oxo-4-phenylbut-2-enoates that then react with CoA in situ to form nanomolar inhibitors of MenB. The potency of these ...
