α-胺基苄基膦酸酯的合成及其生物活性

Synthesis and bioactivity of substituted α-aminobenzylphosphonate

    摘要
  • 摘要: 目的寻找具有内皮依赖性舒张血管活性的新结构胺基膦酸酯类化合物。方法运用一种新型的类Mannich反应，以生物电子等排体原理设计合成了一系列α-胺基苄基膦酸酯类化合物，并运用离体大鼠血管环和离体豚鼠回肠收缩实验观察其舒张血管活性及其对M受体的激动作用。结果共合成了7个新的α-胺基苄基膦酸酯类目标化合物，其结构经IR，1H NMR和元素分析确定。初步离体血管环实验和离体豚鼠回肠收缩实验结果显示，化合物2a，2b和2c有一定的舒张血管活性且不激活平滑肌M受体。结论在浓度为1×10-5 mol·L-1时，化合物2b和2c有较强的舒张血管活性，其舒张率分别为(67±21)%，(82±18)%，而且不激动M受体，其中，化合物2b有内皮依赖性的舒张血管反应。

     

    Abstract: AimTo search for some substituted α-amino phosphonates as leading compounds with the vasodilator effects. MethodsTarget compounds were prepared from benzyl aldehyde, piperazine and diethyl phosphite using alcohol as solvent via Mannich-type reaction. In isolated rat aorta and in isolated guinea pig ileum, the vasodilator effects of compounds were investigated and evaluated whether they activated muscarine receptor. ResultsSeven compounds of substituted α-amino phosphonates have been synthesized and identified by IR, 1H NMR and elemental analysis. Three of them, compound 2a, 2b and 2c have vasodilator activity and do not activate M receptor. ConclusionTwo (2b and 2c) of them were found to have the notable vasodilator effect, and the rates of relaxing are (67±21)% and (82±18)%, separately. But they did not activate M receptors on ileum.
