Novel compounds useful as antihistamine agents, antiallergy agents, and bronchodilators are represented by the following formula ##SPC1## Wherein R.sup.1 represents cyclohexyl, phenyl, or substituted phenyl wherein the substituent on the substituted phenyl is selected from halogen, a straight or branched lower alkyl group of from 1 to 4 carbon atoms, or a lower alkoxy group of from 1 to 4 carbon atoms; R.sup.2 represents hydrogen or hydroxy; R.sup.3 represents hydrogen, or R.sup.2 and R.sup.3 taken together form a second bond between the carbon atoms bearing R.sup.2 and R.sup.3 ; n is an integer of from 1 to 3; Z represents thienyl, naphthyl, phenyl, or substituted phenyl wherein the substituent on the substituted phenyl may be attached at the ortho, meta or para position of the phenyl ring and is selected from halogen, a straight or branched alkyl group of from 1 to 6 carbon atoms, an alkoxy group of from 1 to 6 carbon atoms, a cycloalkyl group of from 3 to 6 carbon atoms, di(lower)alkylamino, or a saturated monocyclic heterocyclic group such as pyrrolidino, piperidino, morpholino, or N-(lower)-alkylpiperazino with the proviso that when R.sup.1 is phenyl, Z is naphthyl or phenyl substituted with a straight or branched alkyl group of 5 or 6 carbon atoms, a lower alkoxy group of 5 or 6 carbon atoms, or a cycloalkyl group of from 3 to 6 carbon atoms. Pharmaceutically acceptable acid addition salts and individual optical and geometric isomers of compounds of the above formula are also included as a part of this invention.
以下式子所代表的新化合物可用作抗组胺剂、抗过敏剂和支气管扩张剂:##SPC1## 其中,R.sup.1代表环己基、苯基或取代苯基,其中取代苯基上的取代基从卤素、1至4个碳原子的直链或支链低烷基或1至4个碳原子的低烷氧基中选择;R.sup.2代表氢或羟基;R.sup.3代表氢,或R.sup.2和R.sup.3共同形成连接R.sup.2和R.sup.3所在碳原子之间的第二键;n为1至3的整数;Z代表噻吩基、萘基、苯基或取代苯基,其中取代苯基上的取代基可以连接在苯环的邻、间或对位,选择自卤素、1至6个碳原子的直链或支链烷基、1至6个碳原子的烷氧基、3至6个碳原子的环烷基、二(低)烷基氨基或饱和的单环杂环基,例如吡咯烷基、哌啶基、吗啉基或N-(低)烷基哌嗪基,但当R.sup.1为苯基时,Z为萘基或取代苯基,取代基为5或6个碳原子的直链或支链烷基、5或6个碳原子的低烷氧基或3至6个碳原子的环烷基。本发明还包括药学上可接受的酸加盐和上述式子化合物的各个光学和几何异构体。
