摘要: A nitrogenated heterocyclic compound represented by the general formula: wherein broken line represents a single bond or double bond; R1, R2, R3, R4 and R5 independently represent hydrogen halogen atom, lower alkyl, aryl, alkoxy monocyclic group which may be substituted like; R6 heterocyclic, dicyclic tricyclic substituted; X1 alkylene X2 alkylene, alkenylene alkynilene X3 an oxygen sulfur sulfiny sulfonyl Y1 cyclic containing bivalent nitrogen Z1 carbon atom like, salt thereof. The has potent antibacterial activity high safety, is therefore useful as excellent agent.
