This article describes the synthesis of 4, 4-diphenyl-2-cycloalkenylamines (3, 5a) including FK584 (S(-)-3a) and 3, 3- or 4, 4-diphenylcycloalkylamines (2, 4, 5b), and their inhibitory activities against detrusor contraction. The order of inhibitory activity (i.v.) of the N-tert-butylamine derivatives against urinary bladder rhythmic contraction in rats was as follows : S(-)-4, 4-diphenyl-2-cyclopentenylamine (FK584, S(-)-3a)>4, 4-diphenylcyclohexylamine (5b)=R(-)-3, 3-diphenylcyclopentylamine (R(-)-4)≥3, 3-diphenylcyclobutylamine (2)≥terodiline hydrochloride (HCl)(1)=RS(±)-4, 4-diphenyl-2-cyclohexenylamine (5a)>R(+)-4, 4-diphenyl-2-cyclopentenylamine (R(+)-3a)≥S(+)-3, 3-diphenylcyclopentylamine (S(+)-4). Although the inhibitory activity of FK584 and compounds R(-)-4 and 5b against detrusor contraction in vitro induced with KCl in guinea-pigs was less potent than that of terodiline HCl, their inhibitory activities against detrusor contractions in vitro induced by electrical field stimulation and carbachol were more potent than those of terodiline HCl.
本文介绍了 4,4-二苯基-2-环烯胺(3,5a)(包括 FK584(S(-)-3a)和 3,3-或 4,4-二苯基环烯胺(2,4,5b))的合成及其对逼尿肌收缩的抑制活性。N- 叔丁基胺衍生物对大鼠膀胱节律性收缩的抑制活性(静脉注射)顺序如下 :S(-)-4,4-二苯基-2-环戊烯胺(FK584,S(-)-3a)>4,4-二苯基环己胺(5b)=R(-)-3,3-二苯基环戊胺(R(-)-4)≥3、3-二苯基环丁基胺 (2)≥ 盐酸特罗地林 (HCl)(1)=RS(±)-4,4-二苯基-2-环己烯胺 (5a)>R(+)-4,4-二苯基-2-环戊烯胺 (R(+)-3a)≥S(+)-3,3-二苯基环戊胺 (S(+)-4)。虽然 FK584 及化合物 R(-)-4 和 5b 对豚鼠体外氯化钾诱导的逼尿肌收缩的抑制活性不及盐酸特罗地林,但它们对体外电场刺激和卡巴胆碱诱导的逼尿肌收缩的抑制活性却强于盐酸特罗地林。
