Copper(II)nitrate catalyzed regioselective protection of primary alcohols with 4,4′-dimethoxytrityl and 2,7-dimethyl-9-phenyl xanthen-9-yl groups in nucleosides and carbohydrates

Regioselective protection of primary hydroxyl group in nucleoside and carbohydrate analogs was accomplished using dimethoxytrityl alcohol (DMTr-OH) or dimethylpixyl alcohol (DMPx-OH) in presence of copper(II)nitrate as a Lewis acid catalyst. Excellent selectivity was observed for the protection of primary hydroxyl group over secondary while glycosidic bond remain unaffected. Utility of this methodology was further exemplified via DMTr- and DMPx-protection of alipahtic acyclic and cyclic diols.

Anti-flavivirus Activity of Different Tritylated Pyrimidine and Purine Nucleoside Analogues

A series of tritylated and dimethoxytritylated analogues of selected pyrimidine and purine nucleosides were synthesized and evaluated for their in vitro inhibitory activity against two important members of the genus Flavivirus in the Flaviviridae family, the yellow fever (YFV) and dengue viruses (DENV). Among all compounds tested, the 5′-O-tritylated and the 5′-O-dimethoxytritylated 5-fluorouridine derivatives exerted potency against YFV. Interestingly in the series of purine analogues, the 5′O, N-bis-tritylated fludarabine derivative revealed strong inhibitory activity against DENV at μm concentrations, however significantly weaker potency against YFV.

Discovery of 4′-chloromethyl-2′-deoxy-3′,5′-di- O -isobutyryl-2′-fluorocytidine (ALS-8176), A first-in-class RSV polymerase inhibitor for treatment of human respiratory syncytial virus infection

Respiratory syncytial virus (RSV) is a leading pathogen of childhood and is associated with significant morbidity and mortality. To date, ribavirin is the only approved small molecule drug, which has limited use. The only other RSV drug is palivizumab, a monoclonal antibody, which is used for RSV prophylaxis. Clearly, there is an urgent need for small molecule RSV drugs. This article reports the design, synthesis, anti-RSV activity, metabolism, and pharmacokinetics of a series of 4′-substituted cytidine nucleosides. Among tested compounds 4′-chloromethyl-2′-deoxy-2′-fluorocytidine (2c) exhibited the most promising activity in the RSV replicon assay with an EC50 of 0.15 μM. The 5′-triphosphate of 2c (2c-TP) inhibited RSV polymerase with an IC50 of 0.02 μM without appreciable inhibition of human DNA and RNA polymerases at 100 μM. ALS-8176 (71), the 3′,5′-di-O-isobutyryl prodrug of 2c, demonstrated good oral bioavailability and a high level of 2c-TP in vivo. Compound 71 is a first-in-class nucleoside RSV polymerase inhibitor that demonstrated excellent anti-RSV efficacy and safety in a phase 2 clinical RSV challenge study.
