Abstract:
New mesoionic 1,3,4-thiadiazolimino-(5) derivatives and their salts which have an aromatic substituent in the 2-position and an acyl radical as substituent on an external nitrogen. The compounds have a central nervous system depressant activity.
Abstract:
P-aminophenol-bis-carbamate derivatives which are suitable as active ingredients in drugs, particularly for inhibiting inflammation, the production of such active ingredients, and drug formulations containing the active ingredients.
Abstract:
Biologically active imidazolino-(1,2-d)-benzo-1,4-thiazepines, their production and their acid addition salts. These compounds, especially as the pharmacologically compatible salts, are useful to dilate coronary vessels of guinea pigs and rabbits and exhibit analgesic, spasmolytic and blood pressure changing properties.
Abstract:
New 1-aminomethylindans and methods of producing them. The compounds are distinguished by their pharmacological effectiveness, particularly by their actions of lowering blood pressure and inhibiting inflammation and by their parasympathicolytic and central nervous system stimulating effects.
Abstract:
The present invention relates to new pyridazinium compounds of the general formula (I): (I) where R1 is hydrogen, R2 denotes -NH2, R3 is hydrogen, R4 denotes the radical -SR6, R6 being an alkyl of 1 to 12 carbon atoms or the radical , the individual radicals R11 being identical or different and denoting hydrogen,alkyl of 1 to 6 carbon atoms, or both radicals R11, together with the nitrogen atom, denoting a pyrrolidine, piperidine or morpholine ring, R5 is phenyl or a lower alkyl, particularly methyl or trifluoromethyl, and ye is an anion of a pharmaceutically acceptable strong inorganic or organic acid; and their production. These compounds have valuable pharmacological properties.
Abstract:
