Two series of compounds having the general structure of C6H5CRR'COOCH2CH2NEt2 were synthesized and examined for their antispasmodic activities. These compounds were selected as structural probes for exploring the nature of muscarinic cholinergic receptor binding sites that interact with atropine-like anticholinergics. These studies indicate a rather strict size limitation for the hydrophobic region
合成了具有C6H5CRR'COOCH2CH2NEt2的一般结构的两个系列的化合物,并研究了它们的解痉活性。选择这些化合物作为结构探针,以探索与阿托品样抗胆碱能药物相互作用的毒蕈碱胆碱能受体结合位点的性质。这些研究表明,对于受体的疏水区域存在相当严格的尺寸限制,并建议分子内氢键作为解释观察到的立体选择性的可能手段。
