A compound of formula (1), wherein: X is an oxygen or sulfur atom; R1 is an aliphatic, cycloaliphatic or cycloalkyl-alkyl- group; R2 is an optionally substituted heteroaromatic group or a -CN group; R3 is a group -(Alk1)mL1(AIk2)nR4 in which m and n, which may be the same or different, is each zero or the integer 1, Alk1 and AIk2, which may be the same or different, is each an optionally substituted aliphatic or heteroaliphatic chain, L1 is a covalent bond or a linker atom or group and R4 is a hydrogen atom or an optionally substituted cycloaliphatic, heterocycloaliphatic, aromatic or heteroaromatic group; A is an optionally substituted cycloaliphatic or heterocycloaliphatic group optionally fused to an optionally substituted aryl or heteroaryl group; R5, which may be attached to any available C or N atom present in the cycloaliphatic or heterocycloaliphatic, or where fused, aryl or heteroaryl group, is a group -(AIk3)tL2(AIk4)vR6 in which t and v, which may be the same or different, is each zero or the integer 1, Alk3 and AIk4, which may be the same or different, is each an optionally substituted aliphatic or heteroaliphatic chain, L2 is a covalent bond or a linker atom or group and R6 is a hydrogen or halogen atom or a -CN group or an optionally substituted cycloaliphatic, heterocycloaliphatic, aromatic or heteroaromatic group; and the salts, solvates, hydrates, tautomers, isomers or N-oxides thereof. The compounds of the present invention are potent inhibitors of IMPDH.
