support of this hypothesis, bicyclic and tricyclic ergoline partial structures 6, 11, 25, and 35 have been synthesized. In addition, some pyrazole isosters (37, 38, 40, and 45) of these rigid pyrroleethylamines have been made. All of the classes show dopaminergic activity in prolactin inhibition and in lesioned rat turning assays. The most potent drugs, the linear tricyclic pyrazoles 38 (R = Pr) and
根据与阿扑吗啡的比较,提出麦角灵的刚性吡咯乙胺部分是负责多巴胺激动剂活性的分子部分。为了支持该假设,已经合成了双环和三环麦角灵部分结构6、11、25和35。另外,已经制备了这些刚性吡咯乙乙胺的一些吡唑等排体(37、38、40和45)。所有这些类别在催乳激素抑制和病变大鼠转弯试验中均显示出多巴胺能活性。最有效的药物是线性三环吡唑38(R = Pr)和40(R = Pr),其功效与高活性麦角灵高培高利特相当(41)。
