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:
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:
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:
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:
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:
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:
Pharmaceutical preparations having an antiphlogistic action are described. The preparations contain, as active ingredient, a benzazole derivative corresponding to the general tautomeric formulae I ##STR1## wherein X represents a sulphur or oxygen atom and R.sup.1 represents a hydrogen atom and R.sup.2 a hydroxymethyl, formyl, lower carbalkoxy or lower acyl group or R.sup.1 and R.sup.2 together represent the group ##STR2## wherein R.sup.3 and R.sup.4 denote, independently of one another, a hydrogen atom or a C.sub.1 -C.sub.6 -alkyl group, or they contain a physiologically acceptable salt thereof. These pharmaceutical preparations are suitable in particular for the treatment of inflammatory conditions and for inhibiting the lipoxygenase and/or cyclooxygenase route of arachidonic acid metabolism.
摘要:
Thiomethylpyridine derivatives having bronchosecretolytic and mucolytic activity according to the formula: ##STR1## wherein R is a group attached in the 2-, 3- or 4-position of the pyridine ring which corresponds to the following general formula:Q--S--CH.sub.2 -- (II)wherein Q is a substituted or unsubstituted aryl group or a 5- or 6-membered heterocyclic group which may optionally contain one or more substituents and/or which may be condensed with an optionally substituted phenyl group or with an optionally substituted heterocycle; R' is a lower alkyl group, a halogen atom or an aminoalkyl group; and n is 0 or an integer of from 1 to 4; and the therapeutically-acceptable acid addition salts thereof.The new compounds are distinguished by surprising activity compared with known compounds, such as "Ambroxol".
