Novel dodecyl-containing azido and glucuronamide-based nucleosides exhibiting anticancer potential

Popis výsledku v původním jazyce

The synthesis and anticancer evaluation of new series of nucleosides constructed on 5/6-azidoglycosyl or glucuronamide moieties and containing an O- or an N-dodecyl chain, respectively, are disclosed. Based on our previous results, their structures were planned to preclude them to act via a similar metabolic pathway than that of clinically used nucleoside antimetabolites, against which cancer cells frequently acquire resistance. Xylo and gluco-configured 5/6-azido-1,2-di-O-acetyl furanosyl and pyranosyl donors containing a 3-O-dodecyl group were synthesized from diacetone-d-glucose and were subsequently coupled with silylated uracil or 2-acetamido-6-chloropurine. N-Dodecyl glucuronamide-based nucleosides were accessed from acetonide-protected glucofuranurono-6,3-lactone, which was converted in few steps into O-benzylated 1,2-di-O-acetyl furanuronamide or pyranuronamide derivatives to undergo further N-glycosylation. Both types of nucleosides demonstrated notorious antiproliferative effects in chronic myeloid leukemia (K562) and in breast cancer (MCF-7) cells. The most potent molecules were a 6′-azidoglucopyranosyl N7-linked purine nucleoside and glucofuranuronamide derivatives comprising N1-linked uracil and N7-linked purine units with activities in the single-digit micromolar order of concentration against both cell lines. Their GI50 values in MCF-7 cells were similar or ca. 3-fold lower than that of the standard drug 5-fluorouracil. Cell cycle studies and immunoblotting analysis of apoptosis-associated proteins in treated K562 cells indicated that the antiproliferative effect of the most effective nucleosides is based on apoptosis induction.
