A series of 4'-thio-D-arabinofuranosylpurine nucleosides was prepared and evaluated as potential anticancer agents. The details of a convenient and high-yielding synthesis of the carbohydrate precursor 1-O-acetyl-2,3,5-tri-O-benzyl-4-thio-D-arabinofuranose (6) are presented. Proof of structure and configuration at all chiral centers of the nucleosides was obtained through an X-ray crystal structure

Patients suffering from cancer are treated by being administered a compound represented by the following formula:
wherein
each R individually is H or an aliphatic or aromatic acyl group;
A is selected from the group consisting of
wherein X is selected from the group consisting of hydrogen, fluorine, alkoxy, alkyl, haloalkyl, alkenyl, haloalkenyl, alkynyl, amino, monoalkylamino, dialkylamino, cyano and nitro. The above compounds also inhibit DNA replication in mammalian cells,
