Derivatives of tetrahydroquinoline of the formula I ##STR1## and acid addition salts thereof, wherein n denotes 2, 3, 4, 5 or 6, R.sup.1 denotes, for example, alkyl, phenyl or pyridyl, R.sup.2 denotes the radical ##STR2## R.sup.3 and R.sup.4 independently of one another denote, for example, hydrogen, alkyl or cycloalkyl and R.sup.5 denotes, for example, hydrogen, alkyl or phenyl, have useful pharmacological properties.
摘要:
Tetrahydropyridazinones of the formula I ##STR1## wherein R denotes an optionally substituted carbocyclic or heterocyclic radical, R.sup.1 denotes hydrogen; alkyl; aralkyl, which is optionally substituted in the aryl part; or acyl, and R.sup.2 denotes hydrogen; alkyl, which can optionally be substituted; or optionally substituted phenyl; and their acid addition compounds, if these can be prepared.The tetrahydropyridazinone derivatives of the formula I according to the invention and their physiologically acceptable salts exhibit useful pharmacological actions.
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.
摘要:
Substituted benzenesulfonylureas and -thioureas of the formula I in which R1, R2, E, X, Y and Z have the meanings described herein, show effects on the autonomous nervous system. The invention relates to the use of the compounds of the formula I in the treatment and prophylaxis of dysfunctions of the autonomous nervous system, in particular of vagal dysfunctions, for example in the case of cardiovascular diseases. The invention also relates to the use of compounds of the formula I in combination with beta-receptor blockers and to products and pharmaceutical preparations which comprise at least one compound of the formula I and at least one beta-receptor blocker, and to novel compounds.
