摘要:
Compounds are disclosed of general formula ##STR1## wherein R.sub.1 represents a hydrogen atom or C.sub.1-4 alkyl or C.sub.2-4 alkenyl group, or the group COANH.sub.2, CSANH.sub.2, or COANHCOCH.sub.2 NH.sub.2 in which A is methylene optionally substituted by a C.sub.1-3 alkyl group; andR.sub.2 represents a hydrogen atom or a C.sub.1-4 alkyl group; or NR.sub.1 R.sub.2 forms a piperidino, piperazino or N-methylpiperazino group;R.sub.3 represents a C.sub.1-4 alkyl group or a benzyl group;R.sub.4 represents a hydrogen or halogen atom; andR.sub.5 represents a hydrogen atom or a C.sub.1-4 alkyl or C.sub.1-4 alkoxy group, with the proviso that one of R.sub.4 and R.sub.5 is a hydrogen atomand physiologically acceptable salts and bioprecursors thereof.The compounds exert effects on the central nervous system and, in particular exhibit anxiolytic and anti-convulsant activity. The compounds may be formulated with pharmaceutically acceptable carriers or diluents for administration in conventional manner.
