Compounds of Formula 1
where X is S and the variables have the meaning defined in the specification are specific or selective to alpha
2B
and/or alpha
2C
adrenergic receptors in preference over alpha
2A
adrenergic receptors, and as such have no or only minimal cardivascular and/or sedatory activity. These compounds of Formula 1 are useful as medicaments in mammals, including humans, for treatment of diseases and or alleviations of conditions which are responsive to treatment by agonists of alpha
2B
adrenergic receptors. Compounds of Formula 1 where X is O also have the advantageous property that they have no or only minimal cardivascular and/or sedatory activity and are useful for treating pain and other conditions with no or only minimal cardivascular and/or sedatory activity.
化合物1的公式中,其中X为S且变量的含义在规范中定义,具有特异性或选择性作用于α2B和/或α2C
肾上腺素受体,而不是α2A
肾上腺素受体,因此具有无或仅极小的心血管和/或镇静作用。这些化合物的1的公式在哺乳动物中,包括人类,用于治疗对α2B
肾上腺素受体激动剂敏感的疾病和/或缓解条件,具有用途。其中X为O的化合物1的公式也具有优越的特性,即它们无或仅极小的心血管和/或镇静作用,并可用于治疗无或仅极小的心血管和/或镇静作用的疼痛和其他病症。
