Their access involved N-glycosylation of uracil and 2-acetamido-6-chloropurine with 5′/6′-azido-1,2-di-O-acetyl glycosyl donors and subsequent Staudinger-phosphite reaction of the resulting azido nucleosides. The coupling of the purine derivative with the pyranosyl donor furnished N 9 A nd N 7linked nucleosides in 1:1 ratio, whereas with the furanosyl donor, the N 9nucleoside was the major regioisomer formed. When using uracil, only 5′/6′-azido N 1linked nucleosides were obtained. The purine 5′/6′-azido nucleosides were converted into corresponding phosphoramidates in good yields. The antiproliferative effects of the nucleoside phosphoramidates and those of the azido counterparts on cancer cells were evaluated. While the nucleoside phosphoramidates did not show significant activities, the purine 5′/6′-azido nucleosides displayed potent effects against K562, MCF-7 and BT474 cell lines. The 5′-azidofuranosyl N 9 and N 7linked purine nucleosides exhibited highest activity towards the chronic myeloid leukemia cell line (K562) with GI 50 values of 13.6 and 9.7 μM, respectively. Among pyranosyl nucleosides, the N 7linked nucleoside was the most active compound with efficacy towards all cell lines assayed and a highest effect on K562 cells (GI 50 =6.8 μM). Cell cycle analysis of K562 and MCF-7 cells showed that the most active compounds cause G2/M arrest.
