Novel imidazoquinolines of the formula ##STR1## wherein X and Y are individually selected from the group consisting of hydrogen, halogen and alkoxy of 1 to 5 carbon atoms, Z is selected from the group consisting of hydrogen, alkyl of 1 to 5 carbon atoms optionally substituted with at least two hydroxyls or protected hydroxyls and ##STR2## n is an integer from 1 to 6 and R.sub.1 and R.sub.2 are individually alkyl of 1 to 5 carbon atoms and taken together with the nitrogen to which they are attached form a saturated heterocyclic ring containing 4 to 6 carbon atoms and optionally interrupted by another heteroatom which further heteroatom is optionally substituted with alkyl of 1 to 5 carbon atoms and non-toxic, pharmaceutically acceptable salts thereof having antiallergic and bronchodilatory activity and their preparations.
新型咪唑喹啉的化学式为##STR1##其中X和Y分别选自氢、卤素和1至5个碳原子的烷氧基组成的群,Z选自氢、1至5个碳原子的烷基,可选地被至少两个羟基或保护羟基取代,并且##STR2##n是1至6的整数,R.sub.1和R.sub.2分别是1至5个碳原子的烷基,并与它们连接的氮一起形成含有4至6个碳原子的饱和杂环环,可选地被另一个杂原子中断,该另一个杂原子可选地被1至5个碳原子的烷基取代,以及其无毒、药学上可接受的盐,具有抗过敏和支气管扩张活性以及它们的制备。
