1
or a pharmaceutically acceptable salt thereof, wherein
X is O or H,H
A is S, NH, N(R
6
), O or a bond;
R
1
is (1-4C)alkyl, (2-4C)alkenyl, phenyl or (2-5C)heteroaryl, the phenyl or heteroaryl ring optionally being substituted with one or more of the group of substituents: hydroxy, halogen, nitro, trifluoromethyl, cyano, amino or (1-4C)(di)alkylamino and
R
2
is H, (1-4C)alkyl, (1-4C)alkoxy(2-4C)alkyl or hydroxy(2-4C)alkyl;
R
3
and R
4
can be independently selected from H and hydroxy(1-4C)alkyl;
R
5
is H or (1-4C)alkyl;
R
6
can be selected from the same groups as described for R
