Antibiotics, lactam

compounds containing a four-membered ring with an amide nitrogen and a keto group. This configuration includes bacteriostatic, cell-wall inhibiting antibiotics, such as penicillins and cephalosporins; their analogs and derivatives, such as the penem (or penam) compounds; clavulanic acids; and monobactams. They are substrates for and may act as inhibitors of bacterial beta-lactamases.
