Abstract

A series of monocyclic thiazepine inhibitors of interleukin-1beta converting enzyme (ICE) were synthesized in eight steps from commercially available intermediates. In vitro biological evaluation showed the thiazepines to be moderately potent ICE inhibitors, with the most active compound exhibiting an IC50 value of 30 nM in an enzyme inhibition assay. Compounds of this class possessed good selectivity against the related enzymes Caspase-3 and Caspase-8.
