development of novel benzamides which are orally active, highly potent, specific antagonists of 5-HT3 receptors. Described in this first report are the structure-activity relationships that led to novel structures with improved potency and selectivity. From this series of compounds, (S)-28 was identified and selected for further evaluation as a 5-HT3 receptor antagonist. Compared with 5-HT3 antagonists such
该报告描述了新型的苯甲酰胺的开发,这些新型的苯甲酰胺是口服活性,高效的5-HT3受体特异性拮抗剂。在该第一份报告中描述的是结构-活性关系,该关系导致了具有改进的效价和选择性的新型结构。从这一系列化合物中,鉴定并选择了(S)-28作为5-HT3受体拮抗剂进行进一步评估。与5-HT3拮抗剂(例如GR 38032F,BRL 43694和甲氧氯普胺)相比,(S)-28在(a)抑制大鼠内嗅皮质中与5-HT3受体结合位点的结合中最活跃,Ki值为0.19 nM,并且(b)用确定为9微克/千克po的ED50值阻断雪貂中顺铂引起的呕吐。
