A series of 8'-substituted N-(endo-8-azabicyclo[3.2.1]oct-3-yl)-1-isopropyl-2-oxo-1, 2-dihydro-3-quinolinecarboxamides were synthesized. The 5-HT4 receptor agonistic activity was evaluated using the isolated guinea pig ileum preparation. Of the compounds synthesized, N-(endo-8-(3-hydroxypropyl)-8-azabicyclo[3.2.1]oct-3-yl)-1-isopropyl-2-oxo-1, 2-dihydro-3-quinolinecarboxamide (15a, TS-951) exhibited the most potent serotonin 5-HT4 receptor agonistic activity. This compound had a high affinity for the serotonin 5-HT4 receptor althought it had no affinities for other broad spectrum receptors. Furthermore, it remarkably enhanced gastrointestinal motility in conscious fed dogs without unfavorable effects that non-selective serotonin 5-HT4 receptor agonist has. TS-951 may be useful in improving gastrointestinal dysfunction.
合成了一系列 8'-取代的 N-(内-8-氮杂双环[3.2.1]辛-3-基)-1-异丙基-2-氧代-1, 2-二氢-3-喹啉甲酰胺。利用离体豚鼠回肠制备物评估了 5-HT4 受体激动活性。在合成的化合物中,N-(内-8-(3-羟基丙基)-8-氮杂双环[3.2.1]辛-3-基)-1-异丙基-2-氧代-1,2-二氢-3-喹啉甲酰胺(15a,TS-951)表现出最强的血清素 5-HT4 受体激动活性。该化合物对血清素 5-HT4 受体有很高的亲和力,但对其他广谱受体没有亲和力。此外,它还能显著增强有意识喂养的狗的胃肠道蠕动,而不会产生非选择性血清素 5-HT4 受体激动剂所具有的不利影响。TS-951 可能有助于改善胃肠功能紊乱。
