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.
化合物的化学式表示为:##STR1## 其中环A是苯环;Ar是芳香族基团;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结合在一起可以形成非芳香族环状碳氢化合物;X是亚甲基或羰基;.........是单键或双键;当.........是单键时,Y是--NR.sup.4--(R.sup.4是H,酰基,碳氢化合物或杂环),当.........是双键时,Y是N;n为1-3,前提是X是羰基且同时R.sup.2和R.sup.3结合在一起形成非芳香族环状碳氢化合物,.........是双键或R.sup.4是杂环或--Z(CH.sub.2).sub.m--W(Z是亚甲基或羰基,W是可选取代的氨基,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。
