antibiotic. Aztreonam is active against Gram-negative bacteria and is still used today. The oral bioavailability of aztreonam in humans is less than 1%. Herein we describe the design and synthesis of potential oral prodrugs of aztreonam.
Antibacterial activity is exhibited by .beta.-lactams having a sulfonic acid salt substituent in the 1-position and an amino or acylamino substituent in the 3-position.
