dog ventricular muscle measured. We have determined that the muscarinic receptor can to a different degree accommodate either a halogen in the ortho, meta, or para position of one phenyl ring or the replacement of one phenyl ring with an alkyl group. Our in vitro competition studies show that the affinities lie within a 270-fold range, from the highest affinity compound, 3-quinuclidinyl alpha-hydro
已经合成了许多3-奎宁环烷基苯磺酸盐(QNB)的类似物,并测量了它们与来自大鼠或狗心室肌的毒蕈碱受体的亲和力。我们已经确定毒蕈碱受体可以在不同程度上容纳一个苯环的邻位,间位或对位中的卤素或一个烷基取代一个苯环。我们的体外竞争研究表明,亲和力处于270倍范围内,从亲和力最高的化合物3-奎宁环烯基α-羟基-α-环戊基苯基乙酸酯(2)到亲和力最低的化合物3-奎宁环烷基α-羟基- α-2-炔丙基苯基乙酸酯(11)。
