R₃ and R₄ independent of each other represent hydrogen, alkyl having 1-10 C-atoms, alkenyl or alkynyl having 3-10 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 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 (R₆)p wherein R₆ and p have the above mentioned meanings, or wherein R₃ + R₄ together with 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 (R₆)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 above-mentioned 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.
