Compounds of the formula II:
in which R8 is of the formula Q-(X)r-CO- wherein either a) X = - CH2-, r = 1, Q is a pyridinium group and R7 is -SO3- or -OSO3-; or b) X = -SCH2- and r = 1; wherein Q is e.g. 1,2,3,4-tetrazol-5-yl and R7 is -SO3H or -OSO3H; or c) X = -CH2NH2-, r = 1 and Q is e.g.
phenyl or a 5-6-membered heterocycle and R7 is -SO3H or -OSO3H; or d) X = -NH2- and r = 1, wherein Q is e.g. phenyl and R7 is - SO3H or -OSO3H; are beta-lactamase inhibitors. They may be used in combination with monobactams against gram-negative bacteria.
