Compounds

A compound of formula (I):

• or a pharmaceutically acceptable salt or solvate thereof, wherein:
• Q is selected from O or S;
• R1 is a monovalent group comprising an aryl or a heteroaryl group;
• R2 is a fused phenyl or a fused 6-membered heteroaryl group, wherein a cycloalkyl, cycloalkenyl, non-aromatic heterocyclic, aryl or heteroaryl ring is fused to the phenyl or the 6-membered heteroaryl group across the 2,3-positions, relative to the point of attachment of the phenyl or the 6-membered heteroaryl group to the remainder of the molecule, wherein the phenyl or the 6-membered heteroaryl group is further substituted at the 4-position, and wherein R2 may optionally be further substituted;
• m is 0, 1, 2, 3 or 4;
• each R3 is independently a halo, —OH, —NO2, —NH2, —N3, —SH, —SO2H, —SO2NH, or a saturated or unsaturated hydrocarbyl group, wherein the hydrocarbyl group may be straight-chained or branched, or be or include cyclic groups, wherein the hydrocarbyl group may optionally be substituted, and wherein the hydrocarbyl group may optionally include one or more heteroatoms N, O or S in its carbon skeleton;
• and
• wherein optionally any R3, and any two adjacent carbon atoms of ring A, may together form a 4- to 12-membered saturated or unsaturated cyclic group fused to ring A, wherein the cyclic group fused to ring A may optionally be substituted.
