The design and synthesis of a potential inhibitor of D-alanine:D-alanine ligase (ADP forming) (EC 6.3.2.4) are described. This enzyme, which catalyzes the second step in the biosynthesis of bacterial peptidoglycan, is believed to generate D-alanyl phosphate as an enzyme-bound intermediate. With tabtoxinine, a potent inhibitor of glutamine synthetase, as a model, beta-lactams 9R and 9S were synthesized as potential precursors of a D-alanyl phosphate mimic.
