Abstract
This invention concerns tetrahydropyridoindoles of the formula: ##STR1## wherein Q represents ##STR2## in which R.sub.3 is hydrogen, C.sub.1-4 alkyl, C.sub.1-4 alkoxy, or --COO(C.sub.1-2) alkyl, and n is an integer from 1 to 7; R.sub.1 is hydrogen, halogen, hydroxy, or C.sub.1-3 alkyl; and R.sub.2 is hydrogen, C.sub.1-4 alkyl or --(CH.sub.2).sub.m --A where A is --N(CH.sub.3).sub.2,--N(C.sub.2 H.sub.5).sub.2, ##STR3## in which Ar is 2-pyrimidinyl, 2-pyrazinyl, phenyl, or phenyl substituted by a methyl, ethyl, methoxy, ethoxy, or trifluoromethyl group; and m is an integer from 1-4, or physiologically acceptable salts thereof, providing however that when n is 1, Q may not be quinolinyl. These compounds exhibit antihypertensive properties. Four of the disclosed compounds also exhibit antipsychotic properties. Also disclosed are compounds of Formula XX in which Q of Formula I is replaced by Q.sub.1, wherein Q.sub.1 is 2- or 3-pyridinyl, and R.sub.2 of Formula I is restricted to hydrogen. The compounds of Formula XX exhibit antipsychotic properties.
