Dipeptide substrates of N-Succinyl Diaminopimelic Acid Aminotransferase (DAP-AT) were converted to hydrazines by treatment with hydrazine and cyanoborohydride. These compounds were tested in vitro as inhibitors of DAP-AT from E. coli and in vivo as antibiotics. The hydrazino-dipeptides showed potent slow binding inhibition of DAP-AT as well as antimicrobial activity. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.

L-glutamate as the amino group donor for its substrate, N-succinyl-R-amino- -ketopimelic acid (1a )( K m )0.18 ( 0.04 mM, kcat ) 86 ( 5s - 1 ). Progress of the reaction is monitored by spectrophotometric observation of decrease in NADPH concentration at 340 nm in a coupled enzyme assay with L-glutamate dehydrogenase (EC 1.4.1.4). Stereochemically pure 1a was synthesized as its trilithium salt by ene reaction
