examined on normotensive and spontaneously hypertensive rats by comparison with dihydralazine (I). 6-Imidazol-1-yl derivatives have proved particularly active. Of these derivatives, 3-hydrazino-6-(2-methylimidazol-1-yl)pyridazine (7c) achieves 4.9 times the activity of dihydralazine when administered orally to spontaneously hypertensive rats. The LD50 values of 7c and dihydralazine are very similar.
描述了具有抗高血压作用的新型6-杂芳基-3-肼基哒嗪的合成和药理活性。通过三种不同的合成方法将吡咯,吡唑,咪唑,三唑,四唑,噻吩,吲哚和咔唑杂环引入到哒嗪核的6位。通过与二肼苯哒嗪(I)进行比较,对降压和自发性高血压大鼠的降压作用进行了检查。已证明6-咪唑-1-基衍生物具有特别的活性。在这些衍生物中,当对自发性高血压大鼠口服时,3-肼基-6-(2-甲基咪唑-1-基)哒嗪(7c)的活性是二肼苯哒嗪的4.9倍。7c和二肼苯哒嗪的LD50值非常相似。
