serotonin and serotonin3 (5-HT3) antagonists using a two-dimensional grid template composed of regular hexagons, we deduced structural modification patterns from agonists to antagonists, and designed new 5-HT3 antagonist prototypes. Among them, 2-(4-methyl-1-piperazinyl)-1-butylbenzimidazole (6) was identified as a lead compound which has potent 5-HT3 antagonistic activity comparable to that of granisetron
通过使用由规则六边形组成的二维网格模板对5-羟色胺和5-羟色胺(5-HT3)拮抗剂进行结构比较研究,我们推导了从激动剂到拮抗剂的结构修饰方式,并设计了新的5-HT3拮抗剂原型。其中,将2-(4-甲基-1-哌嗪基)-1-丁基苯并咪唑(6)鉴定为具有与格拉司琼相当的强5-HT3拮抗活性的先导化合物。我们使用定量构效关系方法优化了6的结构并选择了6-氨基-5-氯-1-异丙基-2-(4-甲基-1-哌嗪基)苯并咪唑二马来酸酯(69,KB-6933),最有效和长效的5-HT3拮抗剂之一,作为候选药物。
