that covalently modify a cysteine thiol often show enhanced pharmacological potency and selectivity. Although reversibleMichaelacceptors have been reported, the structural requirements for reversibility are poorly understood. Here, we report a novel class of acrylonitrile-based Michaelacceptors, activated by aryl or heteroaryl electron-withdrawing groups. We demonstrate that thiol adducts of these acrylonitriles
