Abstract

New 2-oxo-1-azetidine sulfonic acid derivatives with an aminoalkyl substituted "anti" (E-isomer) oxyimino group in the acylamino substituent at the 3 position of the monobactam ring. These compounds are potent inhibitors of bacterial .beta.-lactamases. These compounds can be used in combination with .beta.-lactam antibiotics to increase the effectiveness of the .beta.-lactam antibiotics in fighting infection caused by .beta.-lactamase producing bacteria.
