  A series of 2-(2-aminoethyl) pyridines derived by the modification of the amine moiety in betahistine, 2-(2-methylaminoethyl) pyridine, was synthesized and evaluated for antivertigo action in terms of inhibitory activity against spontaneous nystagmus in cats. The structure-activity relationships between the amine moieties and antivertigo activities were investigated. The effects of substituents on the phenyl ring of the 4-phenylpiperazine moiety were investigated by means of quantitative regression analysis using various physicochemical parameters. The following equation gave the best correlation. log 1/ID30=-0.417 (±0.322) π+0.166 (±0.048) MR-1.473 (±0.237) (n=15, s=0.239, r=0.910, F212=28.887). In this series of compounds, 1-(2-methoxyphenyl)-4-[2-(2-pyridyl) ethyl] piperazine, 1-(2-methoxyphenyl)-4-[2-[2-(6-methyl) pyridyl] ethyl]-piperazine, and 1-(2-methoxyphenyl)-4-[2-[2-(5-ethyl) pyridyl] ethyl] piperazine were found to show more potent activity than betahistine. Thus, the 4-(2-methoxyphenyl) piperazine group was found to be the most effective amine moiety for activity against spontaneous nystagmus.

  通过修改倍他司汀中的胺部分，合成了一系列2-(2-氨基乙基)吡啶，并将其合成的2-(2-甲基氨基乙基)吡啶，就其对猫自发性眼球震颤的抑制活性，评估了它们的抗眩晕作用。研究了胺部分与抗眩晕活性之间的构效关系。通过利用各种物理化学参数进行定量回归分析，研究了4-苯基哌嗪部分苯环上取代基的影响。以下方程给出了最佳相关性。log 1/ID30=-0.417 (±0.322) π+0.166 (±0.048) MR-1.473 (±0.237) (n=15, s=0.239, r=0.910, F212=28.887).在这一系列化合物中，发现1-(2-甲氧基苯基)-4-[2-(2-吡啶基)乙基]哌嗪，1-(2-甲氧基苯基)-4-[2-[2-(6-甲基)吡啶基]乙基]-哌嗪，和1-(2-甲氧基苯基)-4-[2-[2-(5-乙基)吡啶基]乙基]哌嗪的活性强于倍他司汀。因此，发现4-(2-甲氧基苯基)哌嗪部分是对抗自发性眼球震颤活性最有效的胺部分。
