The present invention relates to new aromatic derivatives of formula: ##STR1## wherein: Alk is an alkylene group with 1 to 10 carbon atoms, R.sub.1 is hydrogen or an alkyl with 1 to 6 carbon atoms, R.sub.2 and R.sub.3 are similar or different and represent a cycloalkyl with 3 to 6 carbon atoms or a striaght or branched alkyl with 1 to 6 carbon atoms, either substituted or non-substituted by a phenyl or methyl phenyl group, or R.sub.2 and R.sub.3 form, together with the atom of nitrogen to which they are bonded, a mono-nitrogenous heterocycle containing no other heteroatom, such as pyrrolidino, piperidino, azepino, hexamethylene-imino, 4-methyl-piperidino, 4-phenyl-piperidino, 1,2,3,4-tetrahydro-2-isoquinolyl, 4-benzyl-piperidino; R.sub.4 is hydrogen, halogen, methyl or phenyl, R.sub.5 is hydrogen, halogen or methyl, or R.sub.4 and R.sub.5 together with the benzene ring to which they are bonded, constitute a 1-naphthyl or 2-naphthyl group, and the pharmaceutically acceptable salts with mineral or organic acids. The invention compounds possess interesting antimicrobial properties.
本发明涉及公式为:##STR1##的新芳香衍生物,其中:Alk是具有1到10个碳原子的烷基,R.sub.1是氢或具有1到6个碳原子的烷基,R.sub.2和R.sub.3相似或不同,代表具有3到6个碳原子的环烷基或直链或支链的具有1到6个碳原子的烷基,可以是取代或非取代的苯基或甲基苯基基团,或R.sub.2和R.sub.3与它们结合的氮原子一起形成不含其他杂原子的单氮杂环,例如吡咯啉基,哌啶基,氮杂二环己烷基,己烷亚甲基,4-甲基哌啶基,4-苯基哌啶基,1,2,3,4-四氢-2-异喹啉基,4-苄基哌啶基;R.sub.4是氢,卤素,甲基或苯基,R.sub.5是氢,卤素或甲基,或R.sub.4和R.sub.5与它们结合的苯环一起构成1-萘基或2-萘基基团,以及与矿物质或有机酸形成的药物可接受的盐。本发明化合物具有有趣的抗微生物活性。
