A comparison of the more active polyether toxins which are selective activators of voltage-sensitive sodium channels (VSSC), indicate that these molecules are mostly flat, with a hinge part around the middle of the molecules and a large curvature at one of the ends. Assuming that the receptor is topographically complementary to the active molecules, from the result reported here we could conclude,
比较作为电压敏感钠通道(VSSC)的选择性活化剂的更具活性的聚醚毒素,可以看出这些分子大部分是扁平的,铰链部分围绕着分子的中部,并且在末端之一处具有较大的曲率。假设受体与活性分子在地形上互补,从此处报道的结果可以得出结论,受体区域的特定要求可以通过基于氧烷/氧杂环丁烷部分的完全参与的合成聚醚模型来实现。探索了一种新的收敛方法,该方法通过双还原甲基二缩醛生成氧杂环戊烯环。在寻找生物学模型以进一步表征Na +通道时,我们的研究表明,不同的电压依赖性Na +通道在大鼠子宫中表达,并被短毒素B激活。但是,在这项工作中合成的选定化合物模型未能抑制或激活Na +通道功能。
