The antipurines comprise a group of structural analogues of naturally occurring purine bases and nucleosides which exhibit cell growth inhibitory properties. A large number of purine and purine nucleoside analogues have been investigated for antitumour activity, but of these only a few have proved of sufficient interest as potentially useful clinical anticancer agents to warrant detailed studies of resistance. Such compounds include: 8-azaguanine (AzaG), 6-mercaptopurine (MP), 6-thioguanine (TG), 6-methylthioinosine (MMPR) and 9-β-d-arabinofuranosyladenine (AraA). The chemical structures of these drugs are presented in Fig. 1. The 6-thiopurines, MP and TG, are the only antipurines to achieve widespread routine clinical use in cancer chemotherapy, and consequently they have received considerable attention in the laboratory.
