ring retain gastric activity. Of these 2-substituted compounds, the 2 alpha, 9a alpha isomer has potent selective gastric prokinetic activity with only weak dopamine antagonist properties. Spectroscopic data show that the quinolizidine ring preferentially adopts a trans chair-chair conformation with an axial benzamide moiety. However, energy calculations indicate that, at nondopaminergic receptors controlling
甲氧氯普胺的胃促运动作用可能主要不是由于其多巴胺拮抗剂活性。本发明的目的是通过构象限制胃复安的侧链来获得缺乏多巴胺拮抗剂活性的选择性胃动力药。在一系列喹oli嗪基苯甲酰胺中,只有在喹oli啶环的2位具有苯甲酰胺部分的化合物才能保持胃活性。在这些2-取代的化合物中,2α,9aα异构体具有有效的选择性胃促胃功能,仅具有弱的多巴胺拮抗剂性质。光谱数据表明,喹喔啉环优先采用具有轴向苯甲酰胺部分的反式-椅构象。但是,能量计算表明,在控制胃动力的非多巴胺能受体上,
