Kinetoplastid parasites are the causative agents of neglected tropical diseases with an unmet medical need. These parasites are unable to synthesize the purine ring de novo, and therefore rely on purine salvage to meet their purine demand. Evaluating purine nucleoside analogs is therefore an attractive strategy to identify antikinetoplastid agents. Several anti-Trypanosoma cruzi and anti-Trypanosoma brucei 7-deazapurine nucleosides were previously discovered, with the removal of the 3′-hydroxyl group resulting in a significant boost in activity. In this work we therefore decided to assess the effect of the introduction of a 3′-fluoro substituent in 7-deazapurine nucleosides on the anti-kinetoplastid activities. Hence, we synthesized two series of 3′-deoxy-3′-fluororibofuranosyl and 3′-deoxy-3′-fluoroxylofuranosyl nucleosides comprising 7-deazaadenine and -hypoxanthine bases and assayed these for antiparasitic activity. Several analogs with potent activity against T. cruzi and T. brucei were discovered, indicating that a fluorine atom in the 3′-position is a promising modification for the discovery of antiparasitic nucleosides.

Synthesis of different 3,5-diazidofuranoses: A new and general synthesis pathway

Diamino- and diazidofuranoses represent useful precursors, for example, for the synthesis of substituted nucleosides and metal complexes, respectively. Known procedures for their synthesis lack the availability of cheap starting materials, adequate yields, and the access to all possible diastereomeres. Therefore, 3,5-diazido-3,5-dideoxy- and -2,3,5-trideoxyfuranoses both with ribo- and xylo-configuration were prepared using different approaches.
