Both 2‐nitrooxymethyl‐4‐phenyl‐ (2) and 4‐nitrooxymethylphenyl‐1,4‐dihydropyridines (3) represent new combinations of two different vasodilating structures. 2 could not be isolated due to its spontaneous lactonization. Derivatives of 3 were obtained via Hantzsch synthesis using nitrooxymethylated benzaldehydes. The inotropic potency in isolated porcine trabecular muscles and the vasodilator activity
2-硝基氧甲基-4-苯基-(2)和4-硝基氧甲基苯基-1,4-二氢吡啶(3)都代表了两种不同血管舒张结构的新组合。2由于其自发内酯化而无法分离。使用硝基氧甲基化苯甲醛通过 Hantzsch 合成获得 3 的衍生物。测定了离体猪小梁肌中的正性肌力效力和四种硝基氧苯基二氢吡啶在离体猪冠状动脉中的血管扩张活性。尼群地平 (NTD) 和三硝酸甘油酯 (GTN) 用作参考。3 是负性肌力,然而,小于 NTD 并且 - 除了二氰基衍生物 3d - 大于 GTN。血管扩张剂的特性不如尼群地平和 GTN 明显。血管选择性低。
