Abstract
Metabolically stable arabinose 5-phosphate analogues possessing phosphate mimetic groups at the 5-position were synthesized and evaluated by saturation-transfer-difference (STD) NMR studies for their ability to interact with arabinose 5-phosphate isomerase. Isosteric methylphosphonate 1 and (difluoromethyl)phosphonate 3 were recognised and bound by the catalytic pocket of the enzyme. The synthesized compounds were tested in vivo on E. coli and P. aeruginosa strains in order to evaluate their antibacterial activity. Metabolically stable arabinose 5-phosphate analogues were synthesized and their ability to interact with arabinose 5-phosphate isomerase evaluated by STD-NMR studies. Antibacterial activities of these agents against P. aeruginosa and E. coli were assessed. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
