SYNTHESIS AND BETA-LACTAMASE INHIBITORYACTIVITY OF SODIUM MINOMETHYL-2-ALPHA-METHYLPENAM-3-ALPHA-CARBOXYLATE1,1-DIOXIDE AND SODIUM -BETA-ACYL-2-ALPHA-METHYLPENAM-3-ALPHA-CARBOXYLATE 1,1-DIOXIDE, Bioorganic & medicinal chemistry letters, 7(1), 1997, pp. 11-14
The synthesis and in vitro synergies of (6R)-6-(alpha-hydroxybenzyl)-2
beta-methoxyiminomethyl-2 alpha-methylpenam-3 alpha-carboxylate 1,1-d
ioxide (4) and 2 beta-acyl-2 alpha-methylpenam-3 alpha-carboxylate 1,1
-dioxide (15) are described. Compound 15 showed good in vitro synergy
in combination with piperacillin and ceftazidime against chromosomally
mediated class I cephalosporinase producing organisms including TEM,
SHV, and OXA-type enzymes producing microorganisms. Copyright (C) 1996
