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.
公式1的化合物,其中X为S,变量的含义在规范中定义,对alpha2B和/或alpha2C
肾上腺素受体具有特异性或选择性,而对alpha2A
肾上腺素受体的优先性较低,因此没有或仅有最小的心血管和/或镇静活性。这些公式1的化合物在哺乳动物,包括人类中作为药物治疗对alpha2B
肾上腺素受体激动剂响应性疾病和/或缓解症状非常有用。当X为O时,公式1的化合物也具有无或仅有最小的心血管和/或镇静活性的优越特性,并且对于治疗无或仅有最小心血管和/或镇静活性的疼痛和其他症状也非常有用。
