  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.

  Novel ethynyltriazole ribonucleosides were synthesized using a simple and efficient two-step procedure involving Sonogashira coupling and subsequent ammonolysis. Compounds 2f and 3o inhibited hepatitis C virus (HCV) replication efficiently, whereas compound 3f demonstrated potent apoptosis-induced antiproliferative activity against pancreatic cancer MiaPaCa-2 cells both in vitro and in vivo. Most interestingly, the notable selective antiviral and antiproliferative activities were achieved respectively for 2f and 3f by modulating the ribose sugar moiety into deprotected and protected forms while retaining a similar trifluoromethylphenylethynyltriazole as the nucleobase. Preliminary structure-activity relationship study revealed that not only the ribose moiety but also the CF3 group at the p-position of the phenyl ring and the rigid triple bond functionality contributed critically to the observed antiviral activity of 2f against HCV and antiproliferative activity of 3f against pancreatic cancer. These two compounds constitute therefore promising leads in the search for new antiviral and anticancer candidates.
