Kr. Thompson et al., INHIBITION OF HUMAN-LEUKOCYTE ELASTASE .7. INHIBITION BY 6-SUBSTITUTED PENICILLIN AMIDES, Bioorganic & medicinal chemistry letters, 3(11), 1993, pp. 2289-2294
Penicillin amides substituted at C-6 with either an alpha- or beta-tri
fluoroacetamido or an alpha-alkoxy functionality are reported as human
leukocyte elastase (HLE) inhibitors. The structure activity relations
for these derivatives are discussed and compared to the corresponding
known cephalosporin structures in terms of chemical stability, HLE in
hibition, and efficacy in an intratracheal (IT) lung hemorrhage assay.
