Thiophene derivatives represented by the following general formula (I) or pharmaceutically acceptable salts thereof. Said compounds act as an anti-PCP agonist and therefore are useful as psychotropic or antischizophrenic agents and so on. ##STR1## (In the above formula, R.sub.1 is a formula --A.sub.1 --X.sub.1 --R.sub.3 ; R.sub.2 is a formula --A.sub.2 --X.sub.2 --R.sub.4 or does not exist; B ring is a 7- to 10-membered nitrogen-containing cycloalkyl ring; Ar ring is an aryl or heteroaryl ring; A.sub.1, A.sub.2 and A.sub.3 may be the same or different from one another and each represents a bond or a lower alkylene group; X.sub.1 and X.sub.2 may be the same or different from each other and each represents a bond or a formula --O--, --S--or the like; R.sub.3 and R.sub.4 may be the same or different from each other and each represents a hydrogen atom, a cyclic imido group or a lower alkyl group, a cycloalkyl group, an aryl group or an aralkyl group; with the proviso that, when Ar ring is thiazole ring, either one of A.sub.1 and A.sub.2 is a lower alkylene group. Also, when Ar ring is a benzene ring, a case in which one of R.sub.1 and R.sub.2 is methyl group or a halogen group and the other is a hydrogen atom is excluded.)
以下是由下列通式(I)表示的噻吩衍生物或其药学上可接受的盐。这些化合物作为抗PCP激动剂,因此可用作精神药物或抗精神分裂症药物等。##STR1##(在上述式中,R.sub.1是一个公式--A.sub.1--X.sub.1--R.sub.3; R.sub.2是一个公式--A.sub.2--X.sub.2--R.sub.4或不存在; B环是一个7至10成员的含氮环烷基环; Ar环是一个芳基或杂环基环; A.sub.1,A.sub.2和A.sub.3可能相同也可能不同,每个代表一个键或较低的烷基链; X.sub.1和X.sub.2可能相同也可能不同,每个代表一个键或公式--O--,--S--或类似物; R.sub.3和R.sub.4可能相同也可能不同,每个代表氢原子,环状亚酰基或较低的烷基,环状烷基,芳基或芳基烷基; 前提是,当Ar环为噻唑环时,A.sub.1和A.sub.2中的任一一个是较低的烷基链。此外,当Ar环为苯环时,排除一种情况,即R.sub.1和R.sub.2中的一个是甲基基团或卤素基团,另一个是氢原子。
