α-((Tetronoyl)oxy)- and α-((tetramoyl)oxy)methyl ketone inhibitors of the interleukin-1β converting enzyme (ICE)
摘要:
Aryl-substituted tetronic acids, tetramic acids, and cyclic beta-dicarbonyl moieties were evaluated as leaving groups in the peptidyl-COCH2-X type inhibitor iii. Tripeptidyl aspartyl alpha-((tetronoyl)oxy)- and alpha-((tetramoyl)oxy)methyl ketone derivatives demonstrate potent time-dependent inhibition (k(obs)/[T] 100,000-250,000 M(-1)s(-1)) of the cysteine protease ICE.
