The present invention relates to a cephem prodrug having formula III or formula IV: or a pharmaceutically acceptable salt thereof, wherein R′1is selected from the group consisting of hydrogen and —C(O)CH(NH2)CH3and R′2is selected from the group consisting of hydrogen and an acyl group that is cleaved by an enzyme found in mammals, with the proviso that, when either R′1or R′2is hydrogen, the other is not. A, B, L, G, E, and J are each independently nitrogen or carbon such that the respective rings are selected from the group consisting of provided that the group —CH2—S—CH2CH2NHR′2is attached only to a carbon atom of said heterocyclic group, and Q is selected from the group consisting of nitrogen and —CX, wherein X is selected from the group consisting of hydrogen and chlorine.
