摘要:
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.
摘要:
Pharmacologically-active 3-aminosydnonimines (which are optionally substituted in the N.sup.6 -position) and their physiologically-acceptable acid-addition salts are compounded into standard dosage-form medicament compositions and are useful for prophylaxis for and treatment of cardiovascular-system disorders, such as high blood pressure and angina pectoris. The 3-aminosydnonimines are 3-[4-(lower alkoxy)carbonylpiperazin-1-yl]sydnonimines and 3-[N-(lower alkyl)-N-(tetrahydro-3-thienyl S,S-dioxide)]-sydnonimines.
