This invention relates to indole-7-carboxamide derivatives of the formula ##STR1## where R.sub.1 through R.sub.6 are independently H, loweralkyl, aryl, and aralkyl; and in addition R.sub.3 and R.sub.5 can be joined together to form a piperazine ring of the formula ##STR2## where R.sub.7 is H, loweralkyl, aryl, arylloweralkyl, pyrimidyl; and R.sub.4 and R.sub.5 can be joined together to form a pyrrolidine ring of the formula ##STR3## where R.sub.8 is H, loweralkyl, aryl, arylloweralkyl; X is H, loweralkyl, halogen, NO.sub.2, CF.sub.3, NH.sub.2, and OR.sub.9 ; where R.sub.9 is loweralkyl, arylloweralkyl and n is an integer of 1 to 3; and the pharmaceutically acceptable acid addition salts thereof and the optical isomers thereof where such isomers exist.
这项发明涉及公式为##STR1##的吲哚-7-羧酰胺衍生物,其中R.sub.1到R.sub.6分别为H、低烷基、芳基和芳基烷基;另外R.sub.3和R.sub.5可以结合在一起形成公式为##STR2##的哌嗪环,其中R.sub.7为H、低烷基、芳基、芳基低烷基、嘧啶基;而R.sub.4和R.sub.5可以结合在一起形成公式为##STR3##的吡咯烷环,其中R.sub.8为H、低烷基、芳基、芳基低烷基;X为H、低烷基、卤素、NO.sub.2、CF.sub.3、NH.sub.2和OR.sub.9;其中R.sub.9为低烷基、芳基低烷基,n为1到3的整数;以及其药用可接受的酸盐和光学异构体,如果存在这样的异构体。
