A new beta-lactamase inhibitor,
SYN
-1012, with a penem skeleton was synthesized and its biological activity compared with clavulanic acid, sulbactam, tazobactam and BRL-42715. The beta-lactamase inhibitory activity of
SYN
-1012 was comparable to BRL-42715. Clavulanate and penam sulphones (sulbactam and tazobactam) were more active against
TEM
-1 and OXA-1, but were less active against
TEM
-3 and cephalosporinase (Case) than
SYN
-1012. In combination with piperacillin,
SYN
-1012 exhibited comparable or slightly lower synergistic effects than BRL-42715 against all the Gram-positive and Gram-negative isolates tested with only exception of Pseudomonas aeruginosa. The separate combinations of
SYN
-1012 and BRL-42715 with ceftazidime and cefotaxime provided comparable results against Gram-negatives, but not against Gram-positive isolates. Tazobactam was inferior to
SYN
-1012 in all cases. In comparison to tazobactam,
SYN
-1012 and BRL-42715 were relatively unstable in human and mouse plasma, and in mouse liver and kidney homogenates. Serum level of
SYN
-1012 and BRL-42715 after an intravenous administration of 20 mg/kg in rabbit was undetectable after 1 hour.
