2-(β-d-xylofuranosyl)thiazole-4-carboxamide (2) and two new tiazofurin analogues with 5-hydroxymethyl-2-methyl-tetrahydro-furo[2,3-d][1,3]dioxol-6-ol moiety as a sugar mimic (27 and 28) have been synthesized and evaluated for their in vitro antitumour activity against a panel of human tumour cell lines (K562, HL 60, Jurkat, Raji and HeLa). In contrast to previous literature reports, a metabolic MTT assay revealed remarkable cytotoxicity of 2 against K562 (IC50 = 0.15 μM) and HL-60 (IC50 = 0.13 μM) cells. Flow cytometry data suggest that cytotoxic effects of analogue 2 in the culture of K562 cells might be mediated by apoptosis, in opposite to tiazofurin, which did not induce apoptosis of K562 cells after 24 h, thus suggesting a different mechanism of action. All three analogues 2, 27 and 28 were also active against Jurkat, Raji and HeLa cells, with IC50 values in the range from 0.06 to 5.61 μM, but were completely inactive against the normal foetal lung fibroblasts (MRC-5).

This work describes the synthesis of certain nucleoside synthons which are necessary in order to obtain oligoxylonucleotides.The utilization of a non-symmetrically substituted xyloside substituted at the 2-position permits one to obtain, in satisfactory y
