Neuroleptic activity of 10-(4-methyl-1-piperazinyl)-thieno[3,2-b] [1,5]benzoxazepine and benzothiazepine derivatives.
Two series of compounds, structurally related to clozapine (CAS 5786-21-0), were tested for their neuroleptic activity. The derivatives 7-chloro-10-(4-methyl-1-piperazinyl)-thieno[3,2-b][1,5]benzoxazepine and 7-chloro-10-(4-methyl-1-piperazinyl)-thieno[3,2-b][1,5]benzothiazepine at high doses were not cataleptogenic and only very weakly antagonized the amphetamine-or apomorphine-induced stereotyped behaviour in the rat, whereas at low doses they antagonized the amphetamine-induced hypermotility in mice. Thus these compounds might be efficient neuroleptics with little propensity to cause extrapyramidal side effects. On the other hand, the unsubstituted compound 10-(4-methyl-1-piperazinyl)-thieno[3,2-b][1,5]benzothiazepine appeared to be an efficient neuroleptic agent with a greater propensity to cause these side effects.
