| 目的 合成一系列2-[1-(2-吡啶) 乙氧基]乙酸2-[4-取代哌嗪]乙酯类化合物,对其促小鼠学习记忆作用进行研究。方法 将2-乙基吡啶进行NBS溴代反应,得到α-溴代2-乙基吡啶(2),化合物2与α-羟基乙酸乙酯反应得到芳氧乙酸乙酯(3),化合物3与1-取代-4-羟乙基哌嗪(5a-5g)进行酯交换得到目标化合物2-[1-(2-吡啶)乙氧基]乙酸2-[4-取代哌嗪]乙酯(6a-6g)。 挑选两个化合物6a和6d,对其进行小鼠水迷宫实验,评价其促小鼠学习记忆活性。结果 合成了一系列含哌嗪基团的芳氧乙酸酯类化合物,通过1H-NMR和红外光谱确证了其结构。结论 小鼠水迷宫实验结果表明化合物6a和6d对乙醇所致小鼠学习记忆再现困难具有明显改善作用(P <0.05)。 |

| Objective: To synthesize a series of 2-(4-(4-substituted) piperazin-1-yl) ethyl 2-(1-(pyridin-2-yl) ethoxy) acetates, and study its effects on learning and memory facilitation in mice. Methods: The compounds 2-(4-(4-substituted)piperazin-1-yl)ethyl 2-(1-(pyridin-2-yl)ethoxy)acetates (6a-6g) were prepared by using 2-ethylpyridine as the starting material, which reacted with NBS to obtain compound 2. Compound 2 treated by 2-hydroxyacetic acid ethyl ester to give compound 3. The reaction of intermediate 3 and compounds 5a-5g produced the targets 6a-6g. The effects of compounds 6a and 6d on learning and memory in mice were tested by using swimming maze test. Results: A series of piperazine-contained aryloxy acetates were designed and synthesized, and the structures of these compounds were confirmed by IR and 1H-NMR spectrum. Conclusion:The pharmacological results showed that compound 6a and 6d could significantly improve the aquired dysmnesia of mice caused by 400 mL/L ethanol (P<0.05). |
