7,8-Dihydroxy-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepines having a halo substituent at the 6-position have potent dopaminergic activity. The 6-chloro congeners are most active.
3-Furylmethyl-6-halo-7,8-dihydroxy-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzaze pines have potent dopaminergic activity. As such they have utility as antihypertensive and especially anti-Parkinsonism agents.
3-Furylmethyl- and thienylmethyl-6-halo-7,8-dihydroxy-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzaz epines have potent dopaminergic activity. As such they have utility an antihypertensive and anti-Parkinsonism agents.
