Novel compounds useful as antihistamine agents, antiallergy agents, and bronchodilators are represented by the following formula ##STR1## wherein R and R.sup.1 each represent 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; Y represents --CH.dbd.CH--, or ##STR2## with the proviso that when each of R and R.sup.1 represents hydrogen, Y represents --CH.dbd.CH, and when Y represents --CH.dbd.CH, n is equal to 1 or 2; and 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 geometric isomers of compounds of the above formula are also included as a part of this invention.
新颖的化合物可用作抗组胺剂、抗过敏剂和支气管扩张剂,其化学式如下所示:其中R和R.sup.1分别代表氢原子;或者R和R.sup.1一起形成连接R和R.sup.1碳原子的第二键;n是从1到3的正整数;Y代表--CH.dbd.CH--,或者如下所示:在R和R.sup.1分别代表氢原子时,Y代表--CH.dbd.CH;当Y代表--CH.dbd.CH时,n等于1或2;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连接在苯环的邻位、间位或对位,并且可以选择的取代基包括卤素、由1到4个碳原子组成的直链或支链低碳链烷基、由1到4个碳原子组成的低碳氧基基团、二(低)烷基胺基,或饱和的单环杂环基团,例如吡咯啉基、哌啶基、吗啉基或N-(低)烷基哌嗪基。此发明还包括上述化学式化合物的药学上可接受的酸盐和各种立体异构体。
