  摘要：

  This paper describes the design, synthesis, and biological evaluation of a novel anti-ischemic compound, (2S,3S,4R)-N-(6-amino-3,4-dihydro-2-dimethoxymethyl-3-hydroxy-2-methyl-2H-benzopyranyl)-N'-benzyl-N " -cyanoguanidine (33), and the structure-activity relationships leading to the discovery of this compound. Compound 33 significantly reduced the myocardial infarct zone to area at risk (IZ/AAR) in the ischemic myocardium rat model with high cardioselectivity. Since the cardioprotective effect of compound 33 is reversed by ATP-sensitive potassium channel (K-ATP) blockers, its anti-ischemic effect appears to be at least mediated by K-ATP opening. In addition, compound 33 shows good protective activity on neuronal cells against oxidative stress, and therefore it is suggested that compound 33 may have therapeutic potential both in cardio- and in neuroprotection.

  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。
