A compound or a salt or solvate thereof, of formula (I):
1
in which:
R
1
is hydrogen, alkenyl or alkyl;
R
2
is hydrogen or one or more alkyl groups;
R
5
is hydrogen or alkyl;
R
x
is hydrogen or alkyl; or R
x
together with R
3
represent a bond;
when R
x
is hydrogen or alkyl, then R
z
is hydrogen or alkyl; and
R
3
is selected from hydrogen, optionally substituted alkyl, aryl, aryl-alkyl, cycloalkyl and heterocyclyl; or from hydrogen or an optionally substituted alkyl, aryl, aryl-alkyl, cycloalkyl or heterocyclic group linked to the piperidine ring via>C═O, —O—CO—, —O—CO—NH—, —CO—NH—, —NH—CO— or >SO
2
; and
R
4
is selected from hydrogen, alkyl, —CN, —COR
1
and —OR
1
(where R
1
is as defined above) or a —NR
6
R
7
group, where R
6
and R
7
are selected independently from hydrogen and alkyl, or R
6
is —COR
8
where R
8
is hydrogen, alkyl or optionally substituted aryl, aryl-alkyl, cycloalkyl or heterocyclyl;
or R
3
and R
4
together form a spiro-cyclylalkyl, spiro-heterocyclyl or an unsaturated spiro-carbocyclyl group;
when R
x
together with R
3
represent a bond then:
R
4
is a group R
4x
and R
z
is a group R
3x
;
wherein R
3x
and R
4x
are independently selected from hydrogen or optionally substituted alkyl, aryl, aryl-alkyl, cycloalkyl or heterocyclyl;
