Antibacterial activity has been found in compounds of the formula. Compounds having the formula ##STR1## 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, heteroatoms in the ring selected from nitrogen, ##STR2## 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.
