Abstract: There are disclosed cardiovascularly active compounds possessing antihypertensive properties, and pharmaceutical compositions containing these agents and a method of treating cardiovascular disorders with the compounds. The active components of the pharmaceutical compositions are compounds of formula I ##STR1## wherein R.sub.1 and R.sub.2 are independently chosen from straight chain and branched chain alkyl and olefinic groups, which may be unsubstituted or substituted; or R.sub.1 and R.sub.2 together with the nitrogen atom they are bonded to form a heterocyclic group; and R.sub.3 is a pharmaceutically acceptable organic group selected from alkyl and olefinic groups which may be unsubstituted or substituted, acyl, a sulfonyl, sulfinyl, sulfenyl, carbonate, or carbamate derivative; or R.sub.3 is a group of the formula--(CH.sub.2).sub.n ONN(O)NR.sub.1 R.sub.2, wherein n is 2-8, and R.sub.1 and R.sub.2 are as described above. Novel compounds are disclosed wherein at least one of R.sub.1, R.sub.2 and R.sub.

Abstract: This invention concerns antihypertensive compositions and a method of lowering blood pressure in mammals. The active component of the compositions is a compound of the formula: ##STR1## wherein J is an organic or inorganic moiety, M.sup.+x is a pharmaceutically acceptable cation and the compound decomposes under physiological conditions to release nitric oxide (NO).

Abstract: There are disclosed anti-hypertensive compositions and a method of lowering blood pressure in mammals. The active component in the anti-hypertensive compositions is a compound of the formula ##STR1## wherein R.sub.1 and R.sub.2 are independently selected from straight chain and branched chain C.sub.1 -C.sub.12 alkyl groups and benzyl, with the proviso that no branch occur on the alpha carbon atom of the alkyl group; or R.sub.1 and R.sub.2 together with the nitrogen atom they are bonded to form a heterocyclic ring; M.sup.+X is a pharmaceutically acceptable cation, wherein x is the valence of the cation.
