effects of 21 2- and 3-substituted quinuclidines and some quaternary ammonium derivatives are described. The 2-substituted quinuclidines 2-8 were prepared by alkylation of 2-methylene-3-quinuclidinone. The Wittig reaction with 3-quinuclidinone afforded the 3-substituted derivative 9, which was subsequently converted to 10 and 11. The electrophysiological profiles of the compounds were determined in
描述了21 2和3-取代的奎宁环烷和一些季铵衍生物的合成和心脏电生理作用。通过2-亚甲基-3-奎宁环酮的烷基化制备2-取代的奎宁环烷2-8。与3-奎宁环酮的Wittig反应得到3-取代的衍生物9,其随后转化为10和11。化合物的电生理特性在犬心脏浦肯野纤维和心室肌条中测定。3-[(取代的苯基)烷基]喹核苷选择性地增加了动作电位的持续时间(Vaughan Williams III类活性)。在2-取代的系列中,某些化合物既增加了动作电位的持续时间,又降低了传导速度(I类活性)。对于某些2-取代的奎宁环烷,苯环的适当取代被证明是重要的III类电生理活性的必要条件。所选化合物在麻醉狗的程序化电刺激模型中有效。
