已在大鼠心脏,大鼠脑以及m1或m3转染的CHO细胞中确定了具有2-烷基-2-氮杂双环[2.2.1]庚烷环系统的四种新毒蕈碱拮抗剂和六种潜在毒蕈碱激动剂的放射性配体结合亲和力膜制剂以检查毒蕈碱受体亚型的选择性。潜在毒蕈碱激动剂的功效由对[3H] QNB和[3H] Oxo-M的结合亲和力之比确定。在C5(5-endo或5-exo)或C6(6-endo或6-exo)位置具有2,2-二苯丙酸侧链的四种毒蕈碱拮抗剂不能区分毒蕈碱受体的亚型。2,2-二苯丙酸5-内酯取代的化合物最有效,在大鼠心脏,大鼠大脑中的亲和力介于4.23 x 10(-10)和1.18 x 10(-9)M之间。和m1或m3转染的CHO细胞膜制剂。酯效价的等级顺序为:5-endo大于5-exo大于6-endo大于6-exo。基于为阿扎普芬开发的药效基团进行的分子建模研究被用于解释这些拮抗剂的相对效力。六种潜在的毒蕈碱激动剂在C5或C

cycloaddition sequence instead of a 1,3-diaza-Claisenrearrangement. Competition experiments between isocyanates and isothiocyanates with limiting azanorbornene indicate that isothiocyanates react faster to give the rearrangement product. Since isocyanates are shown to be more electrophilic, these data are consistent with a fast addition step and a rate-determining rearrangement step.
