has been joined with furoxan NO-donor moieties to give new NO-donor beta2-agonists. The furazan analogues, devoid of the property to release NO, were also synthesized for comparison. All the compounds retained beta2-agonistic activity at micromolar or submicromolar concentration when tested on guinea pig tracheal rings precontracted with carbachol. Among the furoxan derivatives, the NO contribution
非诺特罗(一种用于治疗的β2肾上腺素受体激动剂)的结构已与呋喃喃的NO供体基团结合在一起,得到了新的NO供体β2受体激动剂。还合成了不具有释放NO的性质的呋喃赞类似物以进行比较。当在与卡巴胆碱预收缩的豚鼠气管环上进行测试时,所有化合物在微摩尔或亚微摩尔浓度下均保持β2激动活性。在呋喃喃衍生物中,在微摩尔浓度的产物15b中,NO对气管舒张的作用是明显的。所有这些新的NO供体杂种都能够扩张与去氧肾上腺素预收缩的大鼠主动脉条。呋喃喃和呋喃山衍生物均显示出比非诺特罗更大的抗氧化活性。
