| pubmed-article:3643283 | pubmed:abstractText | The inhibitory activity of a series of aryl azolides and sulfonate salts toward human leukocyte elastase is reported. Several of the compounds were found to be potent inhibitors of the enzyme. Active compounds were obtained only when the specificity group and the reactive moiety were separated by a two-carbon chain. The introduction of hydrophobic groups enhanced the inhibitory activity of these compounds, with the exception of the sulfonate salts. The nature of the leaving group had a profound effect on inhibitory activity, with compounds 23 and 26 being the most active (kobsd/[I] = 11,722 and 13,500 M-1 s-1, respectively). | lld:pubmed |
