摘要:
Disclosed are hydrates and polymorphs of 4-[[(7R)-8-cyclopentyl-7-ethyl-5,6,7,8-tetrahydro-5-methyl-6-oxo-2-pteridinyl]amino]-3-methoxy-N-(1-methyl-4-piperidinyl)-benzamide, processes for preparing them and their use as pharmaceutical compositions.
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:
Diamine derivatives corresponding to the general formula IR.sup.1 R.sup.2 N--(CH.sub.2).sub.m --Q--A--NH--R--NH--B--Q'--(CH.sub.2).sub.n NR.sup.3 R.sup.4 (I)which have a highly selective action on histamine-H.sub.2 receptors and are therefore suitable for use as anti-ulcerative agents are described. Processes for the preparation of these compounds and pharmaceutical preparations containing these compounds are also described.

摘要:
New diazine derivatives corresponding to the general formula I ##STR1## and the physiologically acceptable salts thereof are described. The compounds according to the invention are new positive inotropic compounds having a higher and/or more selective action than compounds hitherto known and are therefore suitable for the treatment and prevention of diseases of the heart and circulation.
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 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:
An improved double acting diaphragm pump utilizes at least one supplemental diaphragm and associated pressure chamber arranged coaxially with the connecting shaft of the main diaphragms. The supplemental chambers are connected via parallel pressure lines or conduits to the pressure source for the main diaphragms and associated pressure chambers.
摘要:
Special pyrazole derivatives corresponding to the general formula I which have a highly selective action on histamine-H.sub.2 receptors are described. Compared with other drugs known to be effective in their action on histamine-H.sub.2 receptors, these compounds have improved pharmacological properties. A method of preparation of these compounds is also described.
