synthesized and evaluated for dopaminergic activity. A number of these partial ergoline analogues possess substituents that could mimic the C-8 substituent of the dopaminergic ergolines. Of the unsymmetrically substituted amine series 7a-k, the (monopropylamino)tetrahydroindazole 7b was most interesting as it was found to selectively activate the dopamine (DA) autoreceptor at a dose of 5 mg/kg in rats.

合成了两个系列的四氢吲唑并评估了多巴胺能活性。这些部分麦角灵碱类似物中的许多具有可模仿多巴胺能麦角灵碱的C-8取代基的取代基。在不对称取代的胺系列7a-k中,(单丙基氨基)四氢吲唑7b最令人感兴趣,因为它在大鼠中以5 mg / kg的剂量选择性激活多巴胺(DA)自身受体。如大鼠中血清皮质酮水平的升高所测量,双取代胺7g-k具有明显的DA突触后活性。发现6-取代的5-氨基四氢吲唑10a-d仅具有边缘的多巴胺能活性。
