Compounds represented by the formula: ##STR1## wherein ring A is benzene; Ar is aromatic group; R.sup.1, R.sup.2 and R.sup.3 each stands for H, acyl, hydrocarbon or heterocyclic, or R.sup.2 and R.sup.3, taken together, may form non-aromatic cyclic hydrocarbon; X is methylene or carbonyl; ......... is single bond or double bond; when ......... is single bond, Y is --NR.sup.4 -- (R.sup.4 is H, acyl, hydrocarbon or heterocyclic), when ......... is double bond, Y is N; n is 1-3, provided that, X is carbonyl and, at the same time, R.sup.2 and R.sup.3, taken together, form non-aromatic cyclic hydrocarbon, ......... is double bond or R.sup.4 is a heterocyclic or --Z(CH.sub.2).sub.m --W (Z is methylene or carbonyl, W is optionally substituted amino, and m denotes 0-5), or salts thereof have an excellent GnRH receptor antagonistic action and/or an action of improving sleep disturbances.
该公式代表的化合物为:##STR1## 其中环A为苯;Ar为芳香族基团;R.sup.1、R.sup.2和R.sup.3分别代表H、酰基、碳氢化合物或杂环;或R.sup.2和R.sup.3一起形成非芳香族环烃;X为亚甲基或羰基;.........为单键或双键;当.........为单键时,Y为--NR.sup.4--(R.sup.4为H、酰基、碳氢化合物或杂环);当.........为双键时,Y为N;n为1-3,前提是,X为羰基且同时R.sup.2和R.sup.3一起形成非芳香族环烃,.........为双键或R.sup.4为杂环或--Z(CH.sub.2).sub.m--W(Z为亚甲基或羰基,W为可选择取代的氨基,m表示0-5),或其盐具有出色的GnRH受体拮抗作用和/或改善睡眠障碍的作用。
