    摘要: A compound of general formula ##STR1## wherein X represents a radical selected from the group consisting of one of the formulae ##STR2## in which R.sup.1 represents a radical selected from the group(a) a hydrogen atom,(b) an amino group, when X represents an --OR.sup.1 moiety,(c) an alkyl group having from 1 to 6 carbon atoms(d) an at most binuclear aryl group being unsubstituted or substituted by at most 3 substituents of the group halogen atoms, alkyl, alkoxy, halogenalkyl groups each having up to 4 carbon atoms, cycloalkyl groups having 3 to 6 carbon atoms, nitro and cyano groups; andR.sup.2 and R.sup.3, which may be the same or different, each represents a radical selected from the group(a) a hydrogen atom,(b) an alkyl group having from 1 to 6 carbon atoms, an unsubstituted cycloalkyl group having from 3 to 7 carbon atoms, such cycloalkyl group substituted by at most 3 substituents of the group hydroxy groups and alkoxycarbonyl groups having 1 to 4 carbon atoms,(c) an aralkyl group, a diaralkyl group each having 1 to 4 carbon atoms in the alkyl moiety and being unsubstituted or substituted in at least one of the radicals in the alkyl moiety by hydroxy groups, and in the aryl moieties by at most 3 substituents selected from the group consisting of alkoxy groups having from 1 to 4 carbon atoms and halogen atoms,(d) an at most binuclear aryl group being unsubstituted or substituted by at most 3 substituents selected from the group consisting of alkyl, alkoxy, halogenoalkyl groups each having up to 4 carbon atoms and halogen atoms,(e) a hydroxy group when the other of R.sup.2 and R.sup.3 is hydrogen,(f) R.sup.2 and R.sup.3, together with the nitrogen atom to which they are attached, represent a 5- to 7-membered ring selected from the group consisting of an unsubstituted ring, a ring being substituted by an alkyl group having from 1 to 4 carbon atoms, and a ring being interrupted by a heteroatom selected from the group consisting of oxygen, sulphur and further nitrogen atom, and(g) R.sup.2 and R.sup.3 together with the nitrogen atom to which they are attached, represent a ring from the group a 5-membered heteroaromatic ring containing up to 4 nitrogen atoms and such a ring being anelled to a benzene- or uracil-ring, and physiologically acceptable acid addition salts thereof, a process for their preparation and a pharmaceutical composition containing them.

    摘要: Compounds of general formula ##STR1## wherein one of the groups R.sub.1 and R.sub.3 is a straight-chain or branched oxoalkyl group consisting from 5 to 8 carbon atoms and the oxygen atom is attached to a non-terminal carbon atom and is separated from the nearest ring nitrogen atom by at least 3 carbon atoms in (.omega.-1)-oxoalkyl groups and by at least 4 carbon atoms in oxoalkyl groups in which the oxygen atom is separated from the terminal carbon atom by more than one carbon atom, R.sub.2 and the other one of groups R.sub.1 and R.sub.3 are straight chain or branched alkyl groups containing from 1 to 12 carbon atoms but wherein that group R.sub.1 or R.sub.3 which is other than an oxoalkyl group may also be hydrogen, one nitrogen-bound substituent being hydrogen or alkyl containing more than 1 carbon atom, and physiologically acceptable acid addition salts thereof, a process for their preparation and pharmaceutical compositions containing said compounds.
