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 cardiovascular 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 cardiovascular and/or sedatory activity and are useful for treating pain and other conditions with no or only minimal cardiovascular and/or sedatory activity.
化学式为1的化合物,其中X为S且变量的含义在说明书中定义,具有选择性作用于alpha2B和/或alpha2C
肾上腺素受体,优先于alpha2A
肾上腺素受体,因此几乎没有心血管和/或镇静作用。这些化合物可用作哺乳动物,包括人类,治疗对alpha2B
肾上腺素受体激动剂有反应的疾病和/或缓解条件的药物。
化学式为1且X为O的化合物还具有无或仅极小心血管和/或镇静活性的优点,可用于治疗疼痛和其他无或仅极小心血管和/或镇静活性的疾病。
