imidazoline ring and its replacement by isosteric heterocycles were carried out, proceeding from PMS 812, to evaluate their influence on the antidiabetic activity. The importance of the distance between the imidazoline ring and the piperazine skeleton was studied third. Finally, the influence of the N-benzyl moiety was also analyzed compared to a direct N-phenyl substitution. The pharmacological evaluation
哌嗪衍生物已被鉴定为新的抗糖尿病化合物。一系列1-苄基-4-烷基-2-(4',5'-二氢-1'H-咪唑-2'-基)哌嗪的结构活性关系研究确定了1-甲基-4 -(2',4'-二氯苄基)-2-(4',5'-二氢-1'H-咪唑-2'-基)哌嗪,PMS 812(S-21663),作为一种高效的抗糖尿病药糖尿病大鼠模型,其独立于α2肾上腺素受体阻滞,是由胰岛素分泌的重要增加所介导的。扩展了这些研究以发现这些系列中具有改进性能的其他化合物。以这种方式,首先通过使用各种烷基(支链与否)和苄基来优化两个哌嗪N原子的取代。第二,从PMS 812开始,对咪唑啉环进行了一些修饰并被等位杂环取代,以评估其对降糖活性的影响。第三,研究了咪唑啉环与哌嗪骨架之间距离的重要性。最后,与直接的N-苯基取代相比,还分析了N-苄基部分的影响。使用葡萄糖耐量试验对II型糖尿病大鼠模型进行体内药理学评估。活性最高的化合物是1,4-
