摘要:
New benzimidazoles corresponding to the general formula I ##STR1## are described, in which the pyridazinone ring is attached in the 5- or 6- position of the benzimidazole ring and R.sup.1 denotes a hydrogen atom or a straight chained or branched C.sub.1 to C.sub.4 alkyl group, R.sup.2 denotes a hydrogen atom, a straight chained or branched C.sub.1 to C.sub.4 alkyl group, a C.sub.1 to C.sub.4 alkoxy group, a hydroxy group, a halogen atom, an amino group or a nitro group, A denotes a hydrogen atom, a group of the formula ##STR2## wherein R.sup.3 denotes a hydrogen atom, an optionally substituted C.sub.1 to C.sub.4 alkyl group or a C.sub.1 to C.sub.4 alkoxy group and B denotes a cyano group, a benzoyl group or a phenylsulphonyl group, or A denotes a group of the formula ##STR3## in which m has the value of 2 or 3 and n represents an integer from 1 to 6, and the physiologically acceptable salts thereof as well as processes for their preparation and pharmaceutical preparations containing these compounds. These compounds are new, effective, positive inotropic substances which do not act by the mechanism of phosphodiesterase inhibition.
摘要:
New dihydropryidazinone derivatives corresponding to the following formula ##STR1## and a process for their preparation and pharmaceutical preparations containing these compounds are described. These compounds are effective positively inotropic substances with an improved therapeutic profile.
摘要:
New 6-oxo-pyridazine derivatives corresponding to the general formula I ##STR1## which represent new, positive inotropic compounds having a higher and more selective inotropy-increasing activity are described.A process of preparation and the medical use of these substances or of a medicament containing these substances are also described.
摘要:
New 6-phenyldihydro-3(2H)-pyridazinones corresponding to the following general formula ##STR1## are described. These compounds are readily prepared in a form suitable for oral administration and are distinguished by a high positive inotropic action and have only a slight effect on blood pressure and cardiac frequency. A process for their preparation and pharmaceutical preparations containing these compounds are also described.
摘要:
New guanidine carboxylic acid esters corresponding to the general formula I ##STR1## and a process for the preparation of these compounds are described. The compounds according to the invention are H.sub.2 -agonists optionally having an additional H.sub.1 -antagonistic component. They are distinguished by their improved oral activity. The use of the above-mentioned guanidine carboxylic acid esters and of pharmaceutical preparations containing these esters is also described.
摘要:
The invention relates to a method for characterizing a sample, having the following steps: providing at least one analysis result having a plurality of values, wherein the analysis result was generated by the analysis of a sample by at least one analysis method; determining the value of at least one mathematic relation between at least two values of the plurality of values; generating a characterizing signature of the sample on the basis of the value of the at least one mathematic relation. The invention further relates to a method for characterizing a system in which method the preceding method is used.
