Sažetak

An efficient approach to reversed nucleosides which enables their synthesis in gram quantities is
described. N-1′-Pyrimidine reversed nucleosides were prepared by treating of the sodium salt of pyrimidine
bases with protected 5-tosyl ribose. Additionally, N-1′,N-3′-disubstituted reversed nucleosides were
isolated in the condensation reactions with the 5-halogen pyrimidines. Using the Sonogashira coupling of
5′-iodouracil reversed nucleoside with ethynyltrimethyl silane gave 5′-ethynyl derivative which was further
transformed into 5′-acetyl reversed nucleoside. Biological activity of deprotected reversed nucleosides
was validated on the panel of six human carcinoma cell lines (HeLa, MIAPaCa2, Hep2, NCI-H358,
CaCo-2, and HT-29). 5′-Iodouracil derivative displayed moderate growth inhibition activity against human
colon carcinoma (CaCo-2) cells.
