Re. Dolle et al., 3-CHLORO-4-CARBOXAMIDO-6-ARYLPYRIDAZINES AS A NONPEPTIDE CLASS OF INTERLEUKIN-1-BETA CONVERTING-ENZYME-INHIBITOR, Bioorganic & medicinal chemistry letters, 7(8), 1997, pp. 1003-1006
The 3-chloro-4-carboxamido-6-arylpyridazines are a novel class of inte
rleukin-1 beta converting enzyme (ICE) inhibitor. These agents are irr
eversible inhibitors with pyridazine 23 possessing a k(obs)/[I] = 355
M-1 s(-1). A structure-activity relationship for this non-peptide clas
s of compounds and the putative mechanism for irreversible inactivatio
n are described. (C) 1997 Elsevier Science Ltd.
