This paper describes the design, syntheses, and biological evaluations of novel ATP-sensitive potassium channel (K(ATP)) openers, benzopyranyl indoline and indole derivatives. Among those, two enantiomers of indoline-2-carboxylic ethyl esters (14, 18) showed the best cardioprotective activities both in vitro and in vivo, while their vasorelaxation potencies were very low (concentration for 50% inhibition
本文介绍了新型ATP敏感钾通道(K(ATP))开环剂,苯并吡喃基吲哚和吲哚衍生物的设计,合成和生物学评估。其中,二氢吲哚-2-羧酸乙酯的两种对映体(14、18)在体外和体内均显示出最佳的心脏保护活性,而它们的血管舒张效力却非常低(50%抑制血管舒张的浓度> 30 microM)。14的心脏保护作用被选择性的线粒体K(ATP)阻滞剂5-羟基癸酸酯完全逆转,表明其通过线粒体K(ATP)的开放可证明的保护机制。此外,我们使用2D-NMR,X射线晶体学和分子模型进行了构象分析,以研究该系列化合物的构效关系。
