Biological properties of 3-benzyl-1,2-benzisothiazole compounds

By reaction of 3-chloro-1,2-benzisothiazole with phenylacetonitrile, 3-benzyl-1,2-benzisothiazole derivatives can be obtained. These compounds seem to mimic the benzylisoquinoline structure so they can exhibit spasmolytic activities. Both antimuscarinic and direct muscle-relaxant properties have been found with N,N-dimethyl-3-phenyl-3-(1,2-benzisothiazol-3-yl) propylamine hydrochloride.
