This invention relates to 3-(1-substituted-4-piperazinyl)-1H-indazoles having the following formula ##STR1## wherein R.sub.1 is hydrogen, lower alkyl, arylloweralkyl, acyl, cycloalkylloweralkylene, and phenylsulfonyl: and R.sub.2 is hydrogen, lower alkyl, hydroxyloweralkyl of the formula ##STR2## where Z is selected from hydrogen, halogen, loweralkoxy, CF.sub.3, NO.sub.2, and NH.sub.2 ; ##STR3## where Z is as defined above; ##STR4## where Z is as defined above; ##STR5## where R.sub.3 and R.sub.4 are each independently hydrogen and loweralkyl; ##STR6## where Z is as defined above; ##STR7## where R' and R" are each independently hydrogen and loweralkyl; X is hydrogen, loweralkyl, hydroxyl, halogen, loweralkoxy, CF.sub.3, NO.sub.2 and amino; n is an integer of 1 to 4, with the further proviso that R.sub.2 is not loweralkyl when R.sub.1 is hydrogen or acyl and X is chloro; the pharmaceutically acceptable acid addition salts thereof and where appropriate the geometric isomers, the stereoisomers and racemic mixtures thereof. The compounds of this invention display utility as analgesic and antipsychotic agents.
本发明涉及具有以下通式结构的3-(1-取代-4-哌嗪基)-1H-吲唑类化合物:##STR1## 其中R1为氢、低级烷基、芳基低级烷基、酰基、环烷基低级亚烷基和苯磺酰基;R2为氢、低级烷基、羟基低级烷基,其结构式为##STR2## 其中Z选自氢、卤素、低级烷氧基、CF3、NO2和NH2;##STR3## 其中Z如上定义;##STR4## 其中Z如上定义;##STR5## 其中R3和R4各自独立为氢和低级烷基;##STR6## 其中Z如上定义;##STR7## 其中R'和R"各自独立为氢和低级烷基;X为氢、低级烷基、羟基、卤素、低级烷氧基、CF3、NO2和氨基;n为1至4的整数,但当R1为氢或酰基且X为氯时,R2不应当为低级烷基;其药学上可接受的酸加成盐,以及适当时的几何异构体、立体异构体和外消旋混合物。本发明的化合物显示出作为镇痛剂和抗精神病药物的效用。
