The synthesis of a novel series of smooth muscle relaxants which have been shown to act via the opening or activation of potassium channels is described. Compounds have been evaluated for their ability to inhibit spontaneous tone in guinea pig isolated trachealis and structure-activity relationships are discussed. One compound in particular, 1,1-dimethyl-5-nitro-3-(2-pyridon-1-yl)indan-2-ol, (16) was
描述了一系列新的平滑肌松弛剂的合成,所述平滑肌松弛剂已显示出通过钾通道的开放或激活起作用。已经评估了化合物抑制豚鼠分离的气管中自发音的能力,并讨论了结构-活性关系。一种化合物,特别是1,1-二甲基-5-硝基-3-(2-吡啶-1-基)茚满-2-醇(16)被确定为体外气道平滑肌的有效缓和剂,IC50 =攻击前30-45分钟口服0.15 microM,可显着抑制清醒豚鼠的组胺诱导的呼吸困难。
