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 isomers of compounds of the above formula are also included as a part of this invention.
以下化合物公式代表着可用作抗组胺剂、抗过敏剂和支气管扩张剂的新化合物:##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被选择为卤素、1至4个碳原子的直链或支链低碳基,或1至4个碳原子的低碳氧基;R.sup.2代表氢或羟基;R.sup.3代表氢;或R.sup.2和R.sup.3在一起形成连接R.sup.2和R.sup.3所处碳原子之间的第二个键;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位、间位或对位,并被选择为卤素、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,但是当R.sup.1为苯基时,Z为萘基或取代苯基,所述取代苯基被选择为5或6个碳原子的直链或支链烷基、5或6个碳原子的低碳氧基,或3至6个碳原子的环烷基。本发明还包括上述公式化合物的药学上可接受的酸加盐和个体光学异构体。
