surprisingly discovered to have neuroprotective activities and σ1 binding in vitro. A highly diverse set of Esaprazole analogues 2–5 was prepared in order to increase blood–brain barrier penetration. The analogues showed a structure–activity relationship at the σ1 receptor closely matching already published pharmacophores. Many of the analogues were shown to have neuroprotective properties in two assays using
Esaprazole,分子先前承认,以防止胃和肠道溃疡惊奇地发现有神经保护活动和σ 1体外结合。高度多样化Esaprazole的类似物2 - 5是为了提高血脑屏障渗透制备。所述类似物表现出在σ的结构-活性关系1紧密匹配的已公开的药效受体。在使用暴露于谷氨酸和过氧化氢的皮层神经元的原代培养物的两种测定中,许多类似物被证明具有神经保护特性。但是,无法针对这两种测定法开发出明显的SAR。还研究了类似物的代谢稳定性,并研究了R的结构图1对化合物的ADME性能有重要影响,产生了两个系列的化合物。R 1为H或酰基的化合物在RLM中具有良好的代谢稳定性,但BBB渗透性较差,而R 1为环或双环烷基的化合物具有较弱的代谢稳定性,但BBB渗透性良好。
