Various 2-benzodioxinylaminoethanol derivatives were synthetized and investigated for beta-adrenergic blocking activity. Most compounds demonstrated a beta-blocking activity of a competitive type when evaluated in guinea pig atrial and tracheal preparations. Three compounds were more potent than practolol and propranolol. All compounds demonstrated antihypertensive properties in spontaneously hypertensive
合成了各种2-苯并二氧甲基氨基乙醇衍生物,并研究了其对β-肾上腺素的阻断活性。当在豚鼠心房和气管制剂中评估时,大多数化合物都表现出竞争型的β阻滞活性。三种化合物比普萘洛尔和普萘洛尔更有效。所有化合物在自发性高血压大鼠中均表现出降压作用。活性最高的化合物是1-(1,4-苯并二恶英-2-基)-2- [N4-(2-甲氧基苯基)哌嗪基]乙醇(11),以2.5 mg / kg iv的血压可使血压降低41%。
