Carbapenem Antibiotic

The interaction between imipenem, a carbapenem antibiotic, and two representative beta-lactamases has been studied. The first enzyme was beta-lactamase I, a class-A beta-lactamase from Bacillus cereus; imipenem behaved as a slow substrate (kcat. 6.7 min-1, Km 0.4 mM at 30 degrees C and at pH 7) that reacted by a branched pathway. There was transient formation of an altered species formed in a reversible reaction; this species was probably an acyl-enzyme in a slightly altered, but considerably more labile, conformation. The kinetics of the reaction were investigated by measuring both the concentration of the substrate and the activity of the enzyme, which fell and then rose again more slowly. The second enzyme was the chromosomal class-C beta-lactamase from Pseudomonas aeruginosa; imipenem was a substrate with a low kcat. (0.8 min-1) and a low Km (0.7 microM). Possible implications for the clinical use of imipenem are considered.

Mechanism Of The Reaction

Benzofurazan oxides are formed in excellent yield when certain substituted-2-nitroanilines react with iodosobenzene diacetate in benzene containing 1 per cent. (by volume) of acetic acid. The kinetics of this reaction have been studied. It is considered that the mechanism of the reaction involves a reversible reaction of the 2-nitroaniline with iodosobenzene diacetate to form acetic acid and an intermediate which is then converted to benzofurazan oxide, iodobenzene, and acetic acid. This reaction is therefore similar to the reaction of iodosobenzene diacetate with glycols. The rates of oxidation of substituted-2-nitroanilines could not be correlated with the electrical effect of the substituent. The reasons for this are discussed in detail.
