Abstract: New amine derivatives of 4-hydroxy-2,1,3-benzthiadiazoles of the formula: ##STR1## wherein R is straight-chained or branched alkyl and the pharmacologically compatible salts thereof, that are markedly effected as inhibitors of adrenogenic .beta.-receptors and thus useful for the treatment and prophylaxis of cardiac and circulatory diseases.

Abstract: A 2-cyanoaziridinyl-(1)-2-substituted-aziridinyl-(1)-methane ##STR1## wherein R is a nitrile or carbamoyl group, andR.sub.1 and R.sub.2 each independently is a hydrogen atom, an aliphatic hydrocarbon radical containing up to 10 carbon atoms optionally substituted by hydroxyl, alkoxy, amino, alkylamino, dialkylamino, alkoxycarbonyl, cyano, 1, 2 or 3 halogens, cycloalkyl, phenyl or phenoxy; nitrile, carboxyl, alkoxycarbonyl or optionally hydrogenated monocyclic heteroaryl or phenyl optionally substituted by alkyl, alkoxy, hydroxy, alkoxcarbonyl, dialkylamino, alkylthio, trifluoromethyl, nitro, carbamoyl, nitrile, sulphonamido, hydroxyalkyl, methylenedioxy, or halogen; or R.sub.1 and R.sub.2, together with the carbon atom to which they are attached, form a ring containing up to 8 ring members of which at least one may be oxygen, sulphur, SO, SO.sub.

Abstract: Adenosine-5'-carboxylic acid derivatives of the general formula: ##STR1## wherein Z is two hydrogen atoms or a divalent lower alkylidene radical, ##STR2## R is an aliphatic or arylaliphatic radical, and R.sub.1 and R.sub.2 are independently a hydrogen, hydroxyl, amino, lower alkyl, lower alkenyl, optionally N-alkylated lower aminoalkyl, cycloalkyl, hydroxyalkyl or piperidinyl radical, orR.sub.1 and R.sub.2 taken together are a divalent ethylene radical containing 4-7 carbon atoms optionally interrupted by an oxygen or sulfur atom or by an imino, alkylimino or arylimino radical or a pharmacologically compatible salt thereof.The esters surprisingly can be prepared by esterifying the acid in the presence of sulfuric acid without hydrolyzing the sugar group. While the esters have some activity, they can be used to make the amides which are characterized by marked coronary activity.

Abstract: N(6)-disubstituted adenosine compounds of the formula: ##STR1## wherein R.sub.1 is alkenyl, cycloalkenyl or cycloalkenyl-alkyl; andR.sub.2 is alkenyl, cycloalkenyl, straight or branched-chain alkyl, cycloalkyl, bicycloalkyl, alkyl-cycloalkyl, or alkyl-bicycloalkyl;And the pharmacologically compatible salts thereof; exhibit outstanding anti-lipolytic, anti-hyperlipaemic and anti-hypercholesterolaemic action.

Abstract: New 4-hydroxy-benzimidazole compounds of the formula: ##EQU1## wherein R.sub.1 is straight-chained or branched alkyl andR.sub.2 is hydrogen atom or lower alkylAnd the pharmacologically compatible salts thereof; are outstandingly effective in the treatment and prophylaxis of cardiac and circulatory diseases, and provide substantially greater margins of safety than prior art adrenergic .beta.-receptor inhibitors.

Abstract: New N(6)-disubstituted adenosine compound of the formula ##SPC1##WhereinR.sub.1 is lower alkyl substituted by at least one of hydroxyl, alkoxy or acyloxy; or is cycloalkyl or straight-chained or branched lower alkenyl;R.sub.2 and R.sub.3 are hydrogen, halogen, or nitro or lower alkyl, alkoxy or alkylthio andR.sub.4 is hydrogen or acyl; when R.sub.4 is acyl, R.sub.1 can also be lower alkyl;And the pharmacologicaly compatible salts thereof; exhibits shown anti-lipolytic, anti-hyperlipaemic and anti-hypercholesterolaemic action.
