A compound, or a solvate or salt thereof, of formula (I):
in which:
RCO is an acyl group in which the group R contains a substituted or unsubstituted carbocyclic aromatic or heterocyclic aromatic ring and R₁ and R₂ are independently hydrogen, C₁₋₆ alkyl, C₂₋₆ alkenyl, C₃₋₆ cycloalkyl or C₄₋₁₂ cycloalkylalkyl groups or together form a C₂₋₈ branched or linear polymethylene or C₂₋₆ alkenylene group optionally substituted with a hetero-atom;
R₃ is hydrogen, C₁₋₆ alkyl, preferably methyl or ethyl, or phenyl, or R₃ together with R₁ forms a -(CH₂)₃- or -(CH₂)₄-, group;
R₄ and R₅ are identical and are hydrogen or C₁₋₆ alkyl, or together form a C₂₋₅ linear polymethylene group;
R₆ and R₇ are identical and are hydrogen or C₁₋₆ alkyl, or together form a C₂₋₅ linear polymethylene group;
or R₅ and R₆ are together -CH₂- when each of R₄ and R₇ is hydrogen or C₁₋₆ alkyl;
with the proviso that R₄, R₅, R₆ and R₇ are not simultaneously hydrogen
R₈ and R₉, which may be the same or different, are each hydrogen, C₁₋₆ alkyl, -CH₂OR₁₀, halogen, hydroxy, C₁₋₆ alkoxy, C₁₋₆ alkoxycarbonyl, thiol, C₁₋₆ alkylthio,
-OR₁₁, -NHCOR₁₂, -NHSO₂R₁₃, -CH₂SO₂NR₁₄R₁₅, in which each of R₁₀ to R₁₅ is independently hydrogen, C₁₋₆ alkyl, aryl or aralkyl, is useful for the treatment of pain, and or hyponatraemic disease states and/or cerebral ischaemia.
