compounds may be considered as furan analogs of dialkylaminoethyl benzilate alkiodides. The pA2 values of these compounds as antagonists of acetylcholine were determined on rat jejunum preparation. All four compounds were significantly less potent than the analogous ester antimuscarinic lachesine. The furan ring cannot be substituted for the ester moiety of typical antimuscarinics. Possible modes of binding
制备了5-(二甲基氨基甲基)-和5-(二乙基氨基甲基)-α,α-二苯基糠醇的甲硫醇盐和乙硫醇盐,这些化合物可以被认为是苯甲酸二烷基氨基乙基酯的呋喃类似物。在大鼠空肠制备中测定这些化合物作为乙酰胆碱拮抗剂的pA2值。所有四种化合物的效力均明显低于类似的酯类抗毒蕈碱水ches碱。呋喃环不能取代典型抗毒蕈碱药物的酯部分。认为拮抗剂与先前提出的受体结合的可能模式可能解释了这种抗预期毒蕈碱活性低于预期的原因。
