Abstract: This invention provides a method of inducing cognition enhancement in a mammal by administering to the mammal experiencing a cognition impairment an effective amount of a hydroxycycloalkanephenethyl amine compound of the following structural formula: ##STR1## in which A is a moiety of the formula ##STR2## wherein the dotted line represents optional unsaturation;R.sub.1 is hydrogen or alkyl;R.sub.2 is alkyl;R.sub.4 is hydrogen, alkyl, formyl, or alkanol;R.sub.5 and R.sub.6 are, independently, hydrogen, hydroxyl, alkyl, alkoxy, alkanoyloxy, cyano, nitro, alkylmercapto, amino, alkylamino, dialkylamino, alkanamido, halo, trifluoromethyl, or taken together, methylene dioxy;R.sub.7 is hydrogen or alkyl; andn is 0, 1, 2, 3, or 4;or a pharmaceutically acceptable salt thereof.

Abstract: This application discloses certain substituted phenylacetamides of the formula: ##STR1## in which the dotted line represents optional unsaturation, R.sub.1 is alkyl;R.sub.2 is alkyl;R.sub.4 is hydrogen or alkyl; R.sub.5 and R.sub.6, one of which may be hydrogen, are independently, hydroxyl, alkyl, alkoxy, aralkoxy, alkanoyloxy, alkylmercapto, N-protected amino, halo or trifluoromethyl;R.sub.7 is hydrogen or alkyl; andn is one of the integers 0, 1, 2, 3 or 4;which are useful in the production of antidepressant agents.

Abstract: The compounds ##STR1## in which R.sup.1 is 3-hydroxy, 4-hydroxy, 3-methoxy, 4-methoxy or 3,4-methylenedioxy; n is 1 or 2; and R.sup.2 is ##STR2## where R.sup.3 is hydrogen, alkoxy of 1 to 6 carbon atoms, halo or trifluoromethyl; or a pharmaceutically acceptable salt thereof possess anxiolytic and antidepressant activity and are useful in treating psychiatric disorders involving anxiety and/or depression.

Abstract: This application discloses certain substituted phenylacetonitriles of the formula: ##STR1## in which the dotted line represents optional unsaturation, and R.sub.4 is hydrogen or alkyl;R.sub.5 and R.sub.6, one of which may be hydrogen, are ortho or para substituents, independently selected from the group consisting of hydroxyl, alkyl, alkoxy, aralkoxy, alkanoyloxy, alkylmercapto, halo or trifluoromethyl;R.sub.7 is hydrogen or alkyl; andn is one of the integers 0, 1, 2, 3 or 4;which are useful in the production of antidepressant agents.

Abstract: This invention provides a group of hydroxycycloalkanephenethyl amine antidepressant derivatives of the following structural formula: ##STR1## in which A is a moiety of the formula ##STR2## where the dotted line represents optional unsaturation;R.sub.1 is hydrogen or alkyl;R.sub.2 is alkyl;R.sub.4 is hydrogen, alkyl, formyl or alkanoyl;R.sub.5 and R.sub.6 are, independently, hydrogen, hydroxyl, alkyl, alkoxy, alkanoyloxy, cyano, nitro, alkylmercapto, amino, alkylamino, dialkylamino, alkanamido, halo, trifluoromethyl or, taken together, methylenedioxy;R.sub.7 is hydrogen or alkyl; andn is 0, 1, 2, 3 or 4;or a pharmaceutically acceptable salt thereof.
