摘要
Herein, we examine the potential of a nitrile-containing propionic acid moiety as an electrophile for covalent attack by the active-site cysteine residue of caspase 1. The syntheses of several cyanopropanate-containing small molecules based on the, optimized peptidic scaffold of prodrug VX-765 were accomplished. These compounds were found to be potent inhibitors of caspase 1 (IC50 values <= 1 nM). Examination of these novel small molecules against a caspase panel demonstrated an impressive degree of selectivity for caspase 1 inhibition over other caspase isozymes. Assessment of hydrolytic stability and selected ADME properties highlighted these agents as potentially useful tools for studying caspase 1 down-regulation in various settings, including in vivo analyses.
