3-Aminocycloalkanespiro-5-hydantoins were synthesized and their biological activity was studied. In contrast to hydantoins, these compounds failed to induce either anticonvulsive effects in the central nervous system or inhibitory effects on cholinergic contractions in the enteric nervous system. However, they exerted well pronounced, atropinsensitive, contractile effects on the guinea-pig ileum longitudinal
合成了3-氨基环烷螺螺-5-乙内酰脲,并对其生物学活性进行了研究。与乙内酰脲相反,这些化合物既不能在中枢神经系统中诱导抗惊厥作用,也不能对肠神经系统中的胆碱能收缩产生抑制作用。但是,它们对豚鼠回肠纵向肌肉制剂产生了明显的,对促肌动蛋白敏感的收缩作用。建立的构效关系可以假设:(i)螺旋乙内酰脲分子中环尺寸的减小导致相应类似物诱导收缩作用的效力增加;(ii)在位置3引入-NH2可提高所有研究的化合物产生收缩的能力;(iii)戒指的扩大导致:(1)制剂的脱敏度增加;(2)降低(除1a以外)类似物发挥收缩作用的能力。
