摘要:
Derivatives of 2-spirocyclopropyl 4-acylcephem sulfones of the formula (I) ##STR1## are provided which are useful as potent elastase inhibitors and hence are useful in the prevention, control and treatment of inflammatory conditions, especially arthritis and emphysema.
摘要:
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.
