The present invention relates to quinoline derivatives of the formula
wherein Z is an amino group or a halogen atom,
in which R1 is a hydrogen atom, a lower alkyl or haloalkyl group, R2 is a hydrogen atom or a lower alkyl group, R3 is a lower alkyl or haloalkyl group, R4 is a hydrogen atom or a lower alkyl group, R5 and R6 are the same or different and each represents a hydrogen atom or a lower alkyl group, or R5 and Rs, together with the nitrogen atom to which they are attached, form a heterocyclic ring, and n is 0 or 1, with the proviso that when Z is an amino group R is (B);
and esters thereof and salts thereof and processes for preparation thereof. These compounds show excellent ant- bacterial activity and are useful antibacterial agents.
本发明涉及式中 Z 为氨基或卤素原子的喹啉衍生物,其中 R1 为氢原子、低级烷基或卤代烷基,R2 为氢原子或低级烷基,R3 为低级烷基或卤代烷基,R4 为氢原子或低级烷基,R5 和 R6 相同或不同,且各自代表氢原子或低级烷基,或 R5 和 Rs 与它们所连接的氮原子一起形成杂环,且 n 为 0 或 1,但当 Z 为氨基时,R 为(B);以及其酯和盐及其制备工艺。 这些化合物显示出优异的抗菌活性,是有用的抗菌剂。
