Some pharmacological properties of perhydro-1,4-thiazepine and perhydro-1,2,5-dithiazepine derivatives.

Some newly synthesized perhydro-1,2,5-dithiazepine derivatives have antihistaminic, anticholinergic and spasmolytic properties. One perhydro-1,4-thiazepine derivative, compound 3, produces also a weak local anesthetic effect. The activity of the investigated compounds is lower than that of reference compounds; diphenhydramine, antazoline and papaverine.
