  • Substituted 3-aminosydnonimines, processes for their preparation and their use
    Patent number: 5006540
    Abstract: Substituted 3-aminosydnonimines of the formula I ##STR1## and their pharmacologically acceptable acid addition salts, wherein R.sup.1 denotes, for example, alkyl having 1 to 8 C atoms, R.sup.2 denotes hydrogen or the radical --COR.sup.3 and R.sup.3 denotes, for example, an aliphatic radical having 1 to 4 C atoms, are prepared, for example, by cyclization of a compound of the formula II ##STR2## and if appropriate subsequent acylation and have useful pharmacological properties.
