Abstract: Disclosed herein are compounds of the formula ##STR1## in which Ar is l-naphthyl; R.sup.1 and R.sup.2 are either the same or different selected from the group consisting of hydrogen or lower alkyl, or R.sup.1 and R.sup.2 together with the nitrogen atom to which they are joined form a heterocyclic amine radical selected from the group consisting of 1-pyrrolidinyl, piperidine, morpholine and 4-(lower alkyl)-1-piperazinyl; and R.sup.3 and R.sup.4 are either the same or different selected from the group consisting of hydrogen or lower alkyl, or R.sup.3 and R.sup.4 together with the nitrogen to which they are joined represent a heterocyclic amine radical selected from the group consisting of 1-pyrrolidinyl, piperidino, morpholino and 4-(lower alkyl)-1-piperazinyl; or a therapeutically acceptable acid addition salt thereof. The compounds are antidepressant agents and methods for their preparation and use also are disclosed.

Abstract: This invention relates to 3-(phenyl/naphthyl)benz[d]isothiazole-1,1-dioxides wherein the phenyl or naphthyl substituent possesses an N-heterocyclic moiety in the para position. These compounds are useful as intermediates in the synthesis of certain 3,3-disubstituted-2,3-dihydrobenz[d]isothiazole-1,1-dioxide dyes which find utility as, for example, photographic optical filter agents and filter agent precursors.

Abstract: This invention relates to certain derivatives of phenylalanine having interesting pharmaceutical properties, in particular, a lipid-lowering activity.

Abstract: Novel 3-amino-2-OR-propoxyaryl substituted imidazoles and methods for their preparation are disclosed. These imidazoles, and their salts, exhibit pharmacological activity which includes antihypertensive activity and .beta.-adrenergic blocking activity.

Abstract: N.sup.2 -arylsulfonyl-L-argininamides and the pharmaceutically acceptable salts thereof have been found to be effective as pharmaceutical agents for the inhibition and suppression of thrombosis in mammals.

Abstract: Compounds having the formula ##STR1## and the pharmaceutically acceptable salts thereof, wherein n is 0, 1 or 2; R.sub.1 is alkanoyl; and R.sub.2 is ##STR2## R.sub.3 is alkyl; R.sub.4 is cyano or hydroxy; R.sub.5 is hydroxy or alkanoyloxy; R.sub.6 is hydrogen or alkanoyl; and m is 2, 3 or 4; have useful hypotensive properties.

Abstract: N.sup.2 -naphthalenesulfonyl-L-arginine esters and amides and the pharmaceutically acceptable salts thereof have been found to be effective as pharmaceutical agents for the inhibition and suppression of thrombosis.
