InhA, the enoyl acyl carrier protein reductase (ENR) from M. tuberculosis, is one of the key enzymes involved in the mycobacterial fatty acid elongation cycle and has been validated as an effective antimicrobial target. We report here the discovery, through high-throughput screening, of a series of pyrrolidine carboxamides as a novel class of potent InhA inhibitors. Crystal structures of InhA complexed with three inhibitors have been used to elucidate the inhibitor binding mode. The potency of the lead compound was improved over 160-fold by subsequent optimization through iterative microtiter library synthesis followed by in situ activity screening without purification. Resolution of racemic mixtures of several inhibitors indicate that only one enantiomer is active as an inhibitor of InhA.
