Abstract

Potent and noncovalent inhibitors of caspase-1 were produced by incorporating a secondary amine (reduced amide) isostere in place of the conventional electrophile (eg, aldehyde) that normally confers high potency to cysteine protease inhibitors. Benzyl-or cyclohexylamines produced potent, reversible, and competitive inhibitors that were selective for caspase-1 (eg, K i= 47 nM) over caspases 3 and 8 with minimal cytotoxicity. Unlike ...
