Carneic Acids from an Endophytic Phomopsis sp. as Dengue Virus Polymerase Inhibitors
Résumé
Thirteen carneic acids were isolated from the fungal endophyte Phomopsis sp. SNB-LAP1-7-32. Their structures were identified by mass spectrometry and extensive one- and two-dimensional NMR spectroscopy and through comparison with data reported in the literature. Compounds 1-13 were investigated for their antipolymerase activities against DENV polymerase and Zika NS5. Five of them exhibited significant inhibition of dengue polymerase with IC50 values in the 10 to 20 mu M range without cytotoxicity. None inhibited Zika virus NS5 protein.
