The syntheses of benzamides containing azabicyclo[x.y.z] side chains and their 5-HT4 receptor agonist and 5-HT3 receptor antagonist properties are described. These compounds were designed to mimic higher energy conformations of quinolizidine and indolizidine. High potency was achieved for both activities although an exactly paralleling SAR was not apparent. Introduction of O and S resulted in only
描述了含氮杂双环[xyz]侧链的苯甲酰胺的合成及其5-HT4受体激动剂和5-HT3受体拮抗剂的性质。这些化合物被设计为模拟喹oli嗪和吲哚并idine啶的更高能构象。两种活动均获得了很高的效价,尽管尚不存在完全平行的SAR。O和S的引入仅导致效力的边际差异,这对于5-HT 3拮抗作用更为明显。将甲基α引入碱性氮导致5-HT 4受体激动剂效力降低。鉴定了伦扎必利(5f)进行进一步评估,两种对映体均具有相同的药理学特征,氮杂三环9b也具有相同的药理学特征,其中三者分别包含两种独立对映体的空间体积。
