  Bicyclic nucleoside inhibitors of Varicella–Zoster virus: The effect of branching in the p-alkylphenyl side chain

  摘要：

  Further to the discovery of bicyclic furanopyrimidine nucleoside analogues (BCNAs) as potent anti-VZV agents, a branched series of this family of compounds was synthesised. The aim was to study the impact of the geometry and steric hindrance in the side chain as well as lipophilic role of this moiety on biological activity. The results showed a detrimental effect of branching on antiviral activity, with a different magnitude depending on the position of branching in the side chain. This study again showed the importance of this moiety for biological activity, as well as the limited efficacy of the ClogP value as a tool for predicting the potency of BCNAs, while suggesting an alternative rationale behind the design of future series.

  Reactions of 5-alkynyl-2'-deoxyuridines with dicobalt octacarbonyl Co2(CO)8 in THF at room temperature gave hexacarbonyl dicobalt nucleoside complexes (77-93%). The metallo-nucleosides were characterized, including an X-ray structure of a 1-cyclohexanol derivative. In crystalline form, the Co-Co bond is perpendicular to the plane of the uracil base, which is found in the anti position. The level of

  Starting with 5-iodo-2'-deoxyuridine, a series of 5-alkynyl-2'-deoxyuridines (with n-propyl, cyclopropyl, 1-hydroxycyclohexyl, p-tolyl, p-tert-butylphenyl, p-pentylphenyl, and trimethylsilyl alkyne substituents) have been synthesized via the palladium-catalyzed (Sonogashira) coupling reaction followed by a simplified isolation protocol (76-94% yield). The cytotoxic activity of modified nucleosides
