Novel triazoloquinazolinones of the formula ##STR1## wherein X is selected from the group consisting of hydrogen, halogen, --NO.sub.2, methyl, methoxy and --CF.sub.3, n is an integer from 2 to 5, R.sub.1 and R.sub.2 are individually selected from the group consisting of hydrogen and alkyl and hydroxyalkyl of 1 to 5 carbon atoms and taken together with the nitrogen atom to which they are attached form a saturated heterocycle optionally containing another heteroatom and optionally substituted with at least one member of the group consisting of hydroxy, alkyl and hydroxyalkyl of 1 to 5 carbon atoms, cycloalkyl of 3 to 6 carbon atoms, acyl of an aliphatic carboxylic acid of 1 to 5 carbon atoms, alkoxycarbonyl of 2 to 6 carbon atoms and aryl optionally substituted with a halogen or --CF.sub.3 and their non-toxic, pharmaceutically acceptable acid addition salts having antihistaminic and bronchospasmolytic activity and their preparation.
本发明涉及一种新型三唑喹唑啉类化合物,其化学式为##STR1##其中X选自氢、卤素、--NO.sub.2、甲基、甲氧基和--CF.sub.3的群组,n为2至5的整数,R.sub.1和R.sub.2分别选自氢和1至5个碳原子的烷基和羟基烷基的群组,并与它们所附着的氮原子一起形成饱和的杂环,该杂环可以选择地含有另一个杂原子,并且可以被至少一个羟基、1至5个碳原子的烷基和羟基烷基、3至6个碳原子的环烷基、1至5个碳原子的脂肪酸酰基、2至6个碳原子的烷氧基羰基和苯基取代,以及其非毒性、药学上可接受的酸盐,具有抗组胺和支气管痉挛活性,并且还涉及其制备方法。
