Abstract
Tricyclic nitrogen containing compounds, having central nervous system activity of the following structural formula: ##STR1## and pharmaceutically acceptable salts thereof wherein R.sub.1, R.sub.2, and R.sub.3 are independently hydrogen, C.sub.1-6 alkyl, alkenyl, or alkynyl, C.sub.3-10 cycloalkyl, or R.sub.1 and R.sub.2 are joined to form a C.sub.3-7 cyclic amine which can contain additional heteroatoms; X is hydrogen, C.sub.1-6 alkyl halogen, hydroxy, alkoxy, cyano, carboxamide, carboxyl, or carboalkoxyl; A is SO.sub.2, N, CH, CH.sub.2, CHCH.sub.3, C.dbd.O, C.dbd.S, C-SCH.sub.3, C.dbd.NH, C-NH.sub.2, C-NHCH.sub.3, C--NHCOOCH.sub.3, or C--NHCN. B is CH.sub.2, CH, C.dbd.O, N, NH or N--CH.sub.3 ; n is 0 or 1; and D is CH, CH.sub.2, C.dbd.O, O, N, NH or N--CH.sub.3. These new compounds are suitable for treating schizophrenia, Parkinson's disease, anxiety, depression or as compounds for lowering blood pressure in animal or human hosts.
