摘要:
The invention relates to new pyridine-pyrimidinone derivatives corresponding to the following general formula ##STR1## wherein R.sup.1 represents linear C.sub.1-6 alkyl or cycloalkyl and R.sup.2 represents linear C.sub.1-6 alkyl or R.sup.1 and R.sup.2 together with the nitrogen atom form a pyrrolidine or piperidine ring;Alk represents a linear alkylene chain C.sub.1-6 ;Q represents a benzene ring, furan ring, thiophene ring or thiazole ring;X represents oxygen, Y is a single bond and m is 2, 3 or 4 when Q represents benzene;X represents methylene, Y represents sulfur and m is 2 or 3 when Q is furan, thiophene or thiazole; andR.sup.3 represents a hydrogen atom or a lower alkyl group.These compounds show improved H.sub.2 -antagonistic activity.
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:
Alkanol derivatives corresponding to the general formula IR.sup.1 R.sup.2 N--(CH.sub.2).sub.m --Q--CH.sub.2 X--CH.sub.2 --Y--(CH.sub.2).sub.n --NHR.sup.3 (I)which have a highly selective action on histamine-H.sub.2 receptors are described. Due to this action, these compounds may advantageously be used for treatment of diseases caused by raised gastric secretion.
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.
摘要:
The invention relates to new propan-2-ol derivatives corresponding to the following general formula ##STR1## in which R represents ##STR2## and to salts thereof with pharmacologically acceptable acids. These compounds have a selective effect on histamine-H.sub.2 -receptors.
摘要:
1,3,4-Thiadiazole derivatives corresponding to the general formula I ##STR1## which constitute highly effective inhibitors for histamine-H.sub.2 receptors are described. These compounds in addition have a cytoprotective action.
摘要:
The invention relates to special heterocyclic compounds corresponding to general tautomeric formula I which are distinguished by improved antagonistic activity on histamine-H.sub.2 -receptors. The invention also relates to a process for producing these compounds and to medicaments containing them.
摘要:
The invention provides compounds of the formula (I) in which the substituents and symbols are as defined in the description. The compounds inhibit the secretion of gastric acid.
