modified, was prepared. These compounds were examined for potential bronchodilator activity in an in vitro test that measures relaxation of guinea pig tracheal smooth muscle. Potential cardiac stimulant activity was evaluated in vitro by monitoring changes in the rate of contraction of spontaneously beating guinea pig right atria. Although many of these compounds retained a high degree of potency, all were
沙丁胺醇是一种对气管支气管和心肌具有选择性的肾上腺素能受体激动剂,与儿茶酚胺N-叔丁基去甲肾上腺素的不同之处在于它在间位具有一个羟甲基而不是酚基。为了寻找具有最小的心血管副作用的新的支气管扩张剂,制备了一系列衍生物,其中该间羟甲基被修饰。在一项测量豚鼠气管平滑肌松弛的体外试验中,检查了这些化合物的潜在支气管扩张剂活性。通过监测自发跳动的豚鼠右心房收缩率的变化,在体外评估了潜在的心脏刺激活性。尽管这些化合物中的许多化合物都具有很高的效力,但在气管试验中,所有这些化合物的疗效均不如沙丁胺醇。
