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.
