Trans isomers of 1-piperazino-1,2-dihydroindene compounds having formula (I), ##STR1## wherein X and Y are hydrogen, halogen, trifluoromethyl, alkyl, alkylthio, trifluoromethylthio, alkoxy, hydroxy, alkylsulfonyl, amino, alkylamino, nitro or cyano; Ar is a phenyl, thienyl or furyl group, each optionally substituted; R.sub.1 is hydrogen, or optionally hydroxy substituted alkyl, alkenyl, cycloalkyl or cycloalkylalkyl; R.sub.2 is alkyl, alkenyl, cycloalkyl, or cycloalkylalkyl; or R.sub.1 and R.sub.2 together form a 5 to 7-membered heterocyclic ring fused with the piperazine ring, which ring may be substituted with hydroxy; R.sub.3 is hydrogen, alkyl, alkenyl, cycloalkyl or cycloalkylalkyl; or R.sub.2 and R.sub.3 together form a 3 to 7-membered carbocyclic ring which is spiro-fused to the piperazine ring; and R.sub.4 is hydrogen or alkyl. The compounds of the invention have potent antagonist action on dopamine D.sub.1 receptors and are useful in the treatment of diseases of the central nervous system, such as psychoses, schizophrenia (positive as well as negative symptoms), anxiety, depression, sleep disturbances, migraine, Parkinson's disease or cocaine abuse.
公式(I)的1-哌嗪基-1,2-二氢吲哚化合物的反式异构体,其化学式为:##STR1## 其中X和Y为氢、卤素、三氟甲基、烷基、烷基硫、三氟甲基硫、烷氧基、羟基、烷基磺酰基、氨基、烷基氨基、硝基或氰基;Ar为苯基、噻吩基或呋喃基,每个基团均可选择地被取代;R.sub.1为氢,或者是可选择地被羟基取代的烷基、烯基、环烷基或环烷基烷基;R.sub.2为烷基、烯基、环烷基或环烷基烷基;或者R.sub.1和R.sub.2共同形成一个与哌嗪环融合的5至7成员杂环,该环可能被羟基取代;R.sub.3为氢、烷基、烯基、环烷基或环烷基烷基;或者R.sub.2和R.sub.3共同形成一个与哌嗪环螺合的3至7成员碳环;R.sub.4为氢或烷基。本发明的化合物在多巴胺D.sub.1受体上具有强效的拮抗作用,并可用于治疗中枢神经系统疾病,如精神病、精神分裂症(正性和负性症状)、焦虑、抑郁、睡眠障碍、偏头痛、帕金森病或可卡因滥用。
