The present invention relates to novel compounds corresponding to the formula: ##STR1## in which: n represents an integer between 1 and 8 and optimally 2 or 3; (CH.sub.2).sub.n --N can also form a ring or a heterocycle, for example having 5 to 7 atoms and preferably 6 atoms; R.sub.1 and R.sub.2 can represent hydrogen or a lower alkyl having 1 to 5 carbon atoms or can form, together with the nitrogen, a ring such as pyrrolidine, piperidine, morpholine, thiomorpholine, phenyltetrahydropyridine, piperazine or piperazine N-substituted by an alkyl, a phenyl or a heterocycle; in the case of the phenyltetrahydropyridines and the phenylpiperazines or heteroarylpiperazines, the phenyl or the heterocycle may or may not be substituted by halogens or methoxy, thiomethyl, hydroxyl, nitro, amino, cyano, lower alkyl, trifluoromethyl or trichloromethyl groups; and R.sub.3, R.sub.4 and R.sub.5 can represent hydrogen, a lower alkyl, a hydroxyalkyl or hydroxybenzyl group, a halogen, a trifluoromethyl, a methoxy, a thiomethyl or a nitro or two of them can form a ring, in particular a phenyl in the case of the triazoloquinolines or the triazoloisoquinolines; and the non-toxic acid addition salts. These products are useful as drugs and possess analgesic properties, acting especially on the central nervous system as minor tranquilizers.
本发明涉及通式为##STR1##的新颖化合物,其中:n代表1至8之间的整数,最优选2或3;(CH.sub.2).sub.n --N也可以形成环或杂环,例如具有5至7个原子,优选6个原子;R.sub.1和R.sub.2可以代表氢或具有1至5个碳原子的低级烷基,或者可以与氮一起形成环,如吡咯烷、哌啶、吗啉、硫代吗啉、苯并四氢吡啶、哌嗪或由烷基、苯基或杂环取代的哌嗪N;在苯并四氢吡啶和苯基哌嗪或杂环哌嗪的情况下,苯基或杂环可以被卤素、甲氧基、硫甲基、羟基、硝基、氨基、氰基、低级烷基、三氟甲基或三氯甲基取代或不取代;R.sub.3、R.sub.4和R.sub.5可以代表氢、低级烷基、羟基烷基或羟基苄基、卤素、三氟甲基、甲氧基、硫甲基或硝基,其中两个可以形成环,特别是在三唑并喹啉或三唑并异喹啉的情况下形成苯环;以及无毒的酸加成盐。这些产品作为药物有用,并具有镇痛特性,特别作用于中枢神经系统作为轻度镇静剂。
