6-substituted or 2-alkyl substituted indole or 2,3-dihydroindole derivatives having the general formula
where Ar is optionally substituted phenyl, or a hetero aromatic group ; X is hydrogen, halogen, alkyl, alkoxy, hydroxy, alkylthio, alkylsulfonyl, alkyl- or dialkylamino, cyano, trifluoromethyl, or trifluoromethylthio ; X' is a substituent taken from the X-substituents ; or X and X' are linked to constitute a 5-7 membered carbocyclic ring ; R1 is hydrogen or optionally hydroxy substituted lower alkyl, provided that when X is hydrogen or fluoro, R1 cannot be hydrogen ; Y is nitrogen or carbon ; the dotted lines indicate optional bonds, provided that the two dotted lines may not at the same time indicate bonds ; R is hydrogen, alkyl, alkenyl, cycloalkyl, or cycloalkylmethyl optionally substituted with hydroxy, or R is a group taken from structures 1a and 1b :
wherein n is an integer from 2 to 6 ; W is oxygen or sulfur ; U is nitrogen or carbon ; Z is an optionally substituted 2 or 3 membered divalent carbon chain ; V is oxygen, sulfur, CH2, or NR2, wherein R2 is hydrogen, optionally hydroxy substituted alkyl or alkenyl, or a cycloalkyl or cycloalkylmethyl group ; Vl is oxygen, sulfur, CH2 or N- R5, R5 being defined as R2 above ; R3 is hydrogen, optionally hydroxy substituted alkyl or alkenyl, or a cycloalkyl group ; and R4 is one or two groups taken from the R3-substituents, have long lasting serotonin activity with specific binding to the 5-HT2 receptors in the CNS, thus being suitable for therapeutical treatment of CNS disorders such as anxiety, depression, sleep disturbances, migraine, negative symptoms of schizophrenia, and Parkinson's disease.
6-取代或 2-烷基取代的吲哚或 2,3-二氢吲哚衍生物,其通式为
其中 Ar 是任选取代的苯基或杂芳基;X 是氢、卤素、烷基、烷氧基、羟基、烷硫基、烷基磺酰基、烷基或二烷基氨基、氰基、三氟甲基或三氟甲基硫代;X' 是取自 X 取代基的取代基;或 X 和 X' 连接构成 5-7 位碳环;R1是氢或任选被羟基取代的低级烷基,但当X是氢或氟时,R1不能是氢;Y是氮或碳;虚线表示任选键,但两条虚线不能同时表示键;R是氢、烷基、烯基、环烷基或任选被羟基取代的环烷基甲基,或R是取自结构1a和1b的基团:
其中 n 是 2 到 6 的整数;W 是氧或硫;U 是氮或碳;Z 是任选取代的 2 或 3 位二价碳链;V 是氧、硫、CH2 或 NR2,其中 R2 是氢、任选被羟基取代的烷基或烯基或环烷基或环烷基甲基;Vl 是氧、硫、CH2 或 N-R5,R5 的定义与上述 R2 相同;R3 是氢、任选被羟基取代的烷基或烯基或环烷基;R4 是取自 R3 取代基的一个或两个基团,具有持久的血清素活性,能与中枢神经系统中的 5-HT2 受体特异性结合,因此适用于治疗中枢神经系统疾病,如焦虑症、抑郁症、睡眠障碍、偏头痛、精神分裂症的阴性症状和帕金森病。
