Antibacterial activity has been found in compounds of the formula. Compounds having the formula and pharmaceutically acceptable salts thereof, wherein: A is a bond or alkylene; Q completes a 5- or 6-membered saturated or unsaturated(including aromatic) heterocyclic ring having one or two, hetero atoms in the ring selected from nitrogen sulfur or oxygen; X is attached to an available carbon atom in the heterocyclic ring and is hydrogen or oxo; Y is attached to an available carbon atom in the heterocyclic ring and is hydrogen, amino, hydroxyl, halogen, carboxamide, nitrile, or carboxyl, except that Y is not carboxyl when the bicyclic ring completed by Q is 2-quinolyl, 3-quinolyl, or quinoxalyl; and the remaining symbols are as defined in the specification

Antibacterial activity is exhibited by novel compounds having the formula or a pharmaceutically acceptable salt thereof. R3 and R4 are the same or different and each is hydrogen or alkyl or R3 and R4 taken together with the nitrogen atoms to which they are attached form a 1,2-diazacyclobutane, 1,2-diazacyclopentane, 1,2-diazacyclohexane, or 1,2-diazacycloheptane ring. Y1 and Y2 are either hydrogen or OR11 but are not the same. R11 is hydrogen, alkanoyl of from one to ten carbon atoms, substituted alkanoyl of from two to ten carbon atoms, phenylcarbonyl, (substituted phenyl) carbonyl, heteroarylcarbonyl, phenylalkanoyl, (substituted phenyl) alkanoyl, or heteroarylalkanoyl
