  Bitriazolyl acyclonucleosides synthesized via Huisgen reaction using internal alkynes show antiviral activity against tobacco mosaic virus

  摘要：

  A family of novel bitriazolyl acyclonucleosides were synthesized using a simple and convenient one-step synthetic procedure via the Huisgen reaction by addition of NaN3 onto triazole nucleosides bearing internal alkynyl groups introduced at the 5-position of the triazole ring. Some of the compounds exhibited interesting antiviral activity against tobacco mosaic virus, demonstrating the importance of the bitriazolyl motif for the observed antiviral activity.

  Arylethynyltriazole acyclonucleosides inhibit hepatitis C virus replication

  摘要：

  Novel acyclic triazole nucleosides with various ethynyl moieties appended on the triazole nucleobase were synthesized efficiently using a convenient one-step Sonogashira reaction in aqueous solution and under microwave irradiation. One of the compounds, 1f, inhibited HCV subgenomic replication with a 50% effective concentration (EC50) of 22 mu g/ml and did not inhibit proliferation of the host cell at a concentration of 50 mu g/ml. A preliminary SAR study suggests that the appended phenyl ring as well as the rigid triple bond linker contributes importantly to the anti-HCV activity. (C) 2008 Elsevier Ltd. All rights reserved.
