Dopamine agonist compounds useful in the treatment of hypertension and congestive heart failure in mammals are disclosed. The dopamine agonist compounds include racemic and non-racemic mixtures of chiral compounds as well as optically pure R,R; R,S and S,S stereoisomers which are all intended to be schematically described by the following general formula (I)
wherein:
R₁ is independently hydrogen, lower alkyl, -C(O)R₃, or -C(O)NR₃R₄, wherein
R₃ and R₄ are independently lower alkyl, optionally substituted phenyl or phenyl lower alkyl;
R₂ is hydrogen or lower alkyl-,
X is -(CH₂)m- or -(CH₂)nY(CH₂)n-, where
m is an integer from 1 to 10, n is an integer of 1 to 3, and Y is oxygen or sulfur;
All of R₁, and R₂ are most preferably hydrogen, X is most preferably -(CH₂)m- and the preferred optically pure R stereoisomer (most preferably R,R stereoisomer) of the dopamine agonist is preferably in the form of a pharmaceutically acceptable salt, preferably included in a dosage form with a suitable carrier.
本发明公开了可用于治疗哺乳动物高血压和充血性心力衰竭的多巴胺激动剂化合物。多巴胺激动剂化合物包括手性化合物的外消旋和非外消旋混合物,以及光学纯的 R,R;R,S 和 S,S 立体异构体,它们均按下式(I)示意描述
其中
R₁ 独立地为氢、低级烷基、-C(O)R₃ 或 -C(O)NR₃R₄ ,其中
R₃ 和 R₄ 独立地是低级烷基、任选取代的苯基或苯基低级烷基;
R₂ 是氢或低级烷基、
X 是-(CH₂)m- 或-(CH₂)nY(CH₂)n-,其中
m 是 1 至 10 的整数,n 是 1 至 3 的整数,Y 是氧或硫;
所有 R₁和 R₂ 最优选为氢,X 最优选为-(CH₂)m-,多巴胺激动剂的优选光学纯 R 立体异构体(最优选 R,R 立体异构体)优选为药学上可接受的盐的形式,最好与合适的载体一起包含在剂型中。
