A thiopyran derivative represented by the following formula (I) or (I'), or the salt thereof.
wherein A is S or -CH=CH-; the dotted line indicates that the bond may be either present or absent; Z and Z' are typically
L is an ethylene or trimethylene group; Y is CH or N; n is 2; B is a carbonyl group; m is 0 or 1; D is a phenyl group; and E1 and E2 are hydrogen atoms. These compounds exhibit a strong serotonin-2 blocking action and highly safe. Some compounds also exhibit an α1-blocking action and therefore are useful as an antihypertensive agent with less side effects. Thus, the thiopyran derivatives are useful as drugs for the treatment of circulatory diseases in general such as hypertension, ischemic heart disease, cerebrovascular disturbance, and peripheral circulatory disturbance.
下式(I)或(I')代表的
噻喃衍
生物或其盐。
其中 A 是 S 或-CH=CH-;虚线表示键可以存在或不存在;Z 和 Z'通常是
L 是
乙烯基或三亚甲基;Y 是 CH 或 N;n 是 2;B 是羰基;m 是 0 或 1;D 是苯基;E1 和 E2 是氢原子。这些化合物具有很强的
血清素-2 阻断作用,安全性很高。有些化合物还具有α1阻断作用,因此可用作副作用较小的降压药。因此,
