PYRIDON CARBONATE DERIVATIVE, SALT THEREOF AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: Provided are pyridon carbonate derivatives, salt thereof and a method for manufacturing the same. The novel pyridon carbonate derivatives have antibacterial activity and are thus used as medicines and drugs for animals and fishes. CONSTITUTION: Pyridon carbonate derivative is represented by the formula(1), wherein R1 is a lower alkyl group, a halogen substituted lower alkyl group, a C3-6 cycloalkyl group or a phenyl group by 1-2 of fluoro groups; R2 is hydrogen, a lower alkyl group or an amino group; A is nitrogen, or C-X(wherein, X is hydrogen, halogen, a lower alkyl group or a alkoxy group); and Z is represented by the formula, wherein R3 and R4 represent hydrogen respectively; R5 is a methyl group; and B is an amino group or a lower alkyl group substituted amino group.
