Novel compounds useful as antihistamine agents, antiallergy agents, and bronchodilators are represented by the following formula ##SPC1## Wherein R represents hydrogen or hydroxy; R.sup.1 represents hydrogen; or R and R.sup.1 taken together form a second bond between the carbon atoms bearing R and R.sup.1 ; n is a positive whole integer of from 1 to 3; Z represents thienyl, phenyl, or substituted phenyl wherein the substituents on the substituted phenyl may be attached at the ortho, meta, or para positions of the phenyl ring and are selected from halogen, a straight or branched lower alkyl chain of from 1 to 4 carbon atoms, a lower alkoxy group of from 1 to 4 carbon atoms, di(lower)alkylamino, or a saturated monocyclic heterocyclic group such as pyrrolidino, piperidino, morpholino, or N-(lower)alkylpiperazino. Pharmaceutically acceptable acid addition salts and individual optical isomers of compounds of the above formula are also included as a part of this invention.
以下式子代表了作为抗组胺剂、抗过敏剂和支气管扩张剂有用的新化合物:##SPC1## 其中,R代表氢或羟基;R.sup.1代表氢;或者R和R.sup.1共同形成连接R和R.sup.1的碳原子之间的第二个键;n是1到3的正整数;Z代表噻吩基、苯基或取代苯基,其中取代苯基上的取代基可以附加在苯环的邻位、间位或对位,所选取代基来自卤素、1到4个碳原子的直链或支链低烷基链、1到4个碳原子的低烷氧基、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。药学上可接受的酸盐和上述式子化合物的单一光学异构体也包括在本发明的范围内。
