  • Beschreibung: <jats:title>Abstract</jats:title><jats:p>The synthesis and biological evaluation of novel guanidino sugars as isonucleoside analogs is described. 5‐Guanidino xylofuranoses containing 3‐<jats:italic>O</jats:italic>‐saturated/unsaturated hydrocarbon or aromatic‐containing moieties were accessed from 5‐azido xylofuranoses <jats:italic>via</jats:italic> reduction followed by guanidinylation with <jats:italic>N</jats:italic>,<jats:italic>N</jats:italic>′‐bis(<jats:italic>tert</jats:italic>‐butoxycarbonyl)‐<jats:italic>N</jats:italic>′′‐triflylguanidine. Molecules comprising novel types of isonucleosidic structures including 5‐guanidino 3‐<jats:italic>O</jats:italic>‐methyl‐branched <jats:italic>N</jats:italic>‐benzyltriazole isonucleosides and a guanidinomethyltriazole 3′‐<jats:italic>O</jats:italic>‐dodecyl xylofuranos‐5′‐yl isonucleoside were accessed. The guanidinomethyltriazole derivative and a 3‐<jats:italic>O</jats:italic>‐dodecyl (<jats:italic>N</jats:italic>‐Boc)guanidino xylofuranose were revealed as selective inhibitors of acetylcholinesterase (<jats:italic>K</jats:italic><jats:sub>i</jats:sub>=22.87 and 7.49 μM, respectively). The latter also showed moderate antiproliferative effects in chronic myeloid leukemia (K562) and breast cancer (MCF‐7) cells. An aminomethyltriazole 5’‐isonucleoside was the most potent molecule with low micromolar GI<jats:sub>50</jats:sub> values in both cells (GI<jats:sub>50</jats:sub>=6.33 μM, 8.45 μM), similar to that of the drug 5‐fluorouracil in MCF‐7 cells. Moreover, the most bioactive compounds showed low toxicity in human fibroblasts, further indicating their interest as promising lead molecules.</jats:p>
