reported which irreversibly tethers drug-like fragments to catalytic cysteines. We attached an electrophile to 100 fragments without significant alterations in the reactivity of the electrophile. A mass spectrometry assay discovered three nonpeptidic inhibitors of the cysteineprotease papain. The identified compounds display the characteristics of irreversibleinhibitors. The irreversible tethering system
