    • DIR 0482 The invention relates to compounds having anti-ischaemic activity, memory enhancing activity and anti-convulsive activity of the formulae 1A and 1B (1A) (1B) wherein -R1 + R2 together form an alkylene group having 1-3 C-atoms which may be substituted with one or more alkyl group(s) having 13 C-atoms; -Z is methylene optionally substituted with one alkyl group having 1-3 C-atoms, or with one phenylalkyl group with 1-3 C-atoms in the alkyl group, which phenyl group may be substituted with a group (R5)p wherein. R6 is halogen, hydroxy, alkyl or hydroxyalkyl having 1-5 C-atoms, alkoxy having 1-3 C-atoms, S-alkyl, S(O)-alkyl or S(O)2-alkyl having 1-3 Catoms, amino, mono- or dialkylamino having 1-3 C-atoms per alkyl group, trifluoromethyl, trifluoromethoxy, a sulphonylamido group SO2NHR or a carbalkoxy group COOR wherein R is alkyl having 1-4 C-atoms, the group COOH, SO3H,CONH2, the amidino group or cyano group, and p has the value 0-3; -R3 and R4 independent of each other represent hydrogen, alkyl having 1-10 C-atoms, alkenyl or alkynyl having 3-10 Catoms, cycloalkyi having 3-8 C-atoms, cycloalkyl-alkyl having 3-8 ring atoms and 1-5 C-atoms in the alkyl group, phenylalkyl or heteroaryl-alkyl having 1-5 C-atoms in the alkyl group, phenylalkenyl, heteroaryl-alkenyl, phenylalkynyl or heteroaryl-alkynyl group having 3-5 C-atoms in the alkenyl group or alkynyl group, which groups R3 and R4 may be substituted with a group (R8)p wherein R6 and p have the above mentioned meanings, or wherein R3+R4 together with DIR 0482 the nitrogen atom form a saturated or unsaturated heterocyclic group of 5-7 ring atoms, which may contain a second hetero-atom from the group consisting of oxygen, sulphur and nitrogen, which ring may be substituted with a group (R5)p wherein R6 and p have the above mentioned meanings, or with phenylalkyl, heteroarylalkyl, phenylalkenyl, heteroaryl-alkenyl, phenylalkynyl or heteroaryl-alkynyl having at most 3 C-atoms in the alkyl, alkenyl or alkynyl part, which groups may be substituted with a group (R6)p wherein R6 and p have the above-mentioned meanings, or which ring may be annelated with a phenyl group; -R5 is alkyl having 1-12 C-atoms, alkenyl or alkynyl having 3-12 C-atoms, cycloalkyl having 3-8 C-atoms, cycloalkyl-alkyl having 3-8 ring atoms and 1-5 C-atoms in the alkyl group, phenylalkyl or heteroaryl-alkyl having 1-5 C-atoms in the alkyl sub-group, phenylalkenyl, heteroaryl-alkenyl, phenylalkynyl or heteroaryl-alkynyl having 3-5 C-atoms in the alkenyl subgroup or alkynyl sub-group, which groups may be substituted with a group (R6)p, wherein R6 and p have the abovementioned meanings, and which alkyl sub-groups, alkenyl sub-groups and alkynyl sub-groups may contain a group -O-, S- or CO, or a pharmacologically acceptable salt thereof
