Novel ((2-substituted-1H-benzo [d] imidazol-1-yl) methyl) benzamides were found to be excellent P1′ substituents in conjunction with unique constrained β-amino hydroxamic acid scaffolds for the discovery of potent selective inhibitors of TNF-α Converting Enzyme (TACE). Optimized examples proved potent for TACE, exceptionally selective over a wide panel of MMP and ADAM proteases, potent in the suppression of LPS-induced TNF-α in human ...
