Figure 1. Comparison of the Chemical Structures of Several b-Lactamase Ligands(A) Ampicillin, a b-lactamase substrate.(B) Ceftazidime, a b-lactamase-resistant molecule. The R1 side chain ubiquitous among b-lactams is labeled.(C) A boronic acid transition-state analog inhibitor that contains the R1 side chain from ceftazidime [9].(D) Compound 1, 3-[(4-chloroanilino) sulfonyl]thiophene-2-carboxylic acid, a novel, competitive inhibitor of b-lactamase.
