The synthesis and antihypertensive activity of a series of novel 4-(substituted-carbonylamino)-2H-1-benzopyran-3-ols, administered orally to conscious spontaneously hypertensive rats, are described. Optimum activity was observed for compounds with alkyl, amino, or aryl groups flanking the carbonyl group. Of the alkyl and amino series the most potent compounds contained the methyl and methylamino groups
描述了口服给予有意识的自发性高血压大鼠的一系列新型4-(取代-羰基氨基)-2H-1-苯并吡喃-3-醇的合成和降压活性。对于具有在羰基侧翼的烷基,氨基或芳基的化合物,观察到最佳活性。在烷基和氨基系列中,最有效的化合物分别包含甲基和甲基氨基。已使用-86作为标记物,将几种类似物与cromakalim(1)对兔肠系膜动脉钾离子外流的作用进行了比较。每种化合物增强rub 86流出的能力与其降血压活性大致平行,因此这些类似物(如化合物(1))属于已归类为钾通道激活剂的一系列药物。
