, an optionally substituted aryl or an optionally substituted aralkyl, and a hydroxy group that may undergo a C═O tautomeric rearrangement; and Y comprises an unsubstituted or substituted 4- to 8-membered carbocyclic or heterocyclic ring, optionally forming part of a larger fused ring structure, or consists of an optionally substituted linear or branched hydrocarbon chain. These purine derivatives are potential chemotherapeutic agents and, accordingly, the present invention also relates to the use of these compounds in the treatment of tumours or other cell proliferation disorders and pharmaceutical compositions comprising these compounds.
