Isolation, structural determination, and antiviral activities of metabolites from vanitaracin A-producing Talaromyces sp.

Vanitaracin A, an anti-hepatitis B virus polyketide, has been previously isolated from Talaromyces sp. In the present study, we searched for novel compounds in the culture broth obtained from a vanitaracin A-producing fungus under various conditions. Three novel compounds (vanitaracin C, vanitaraphi...

description Vanitaracin A, an anti-hepatitis B virus polyketide, has been previously isolated from Talaromyces sp. In the present study, we searched for novel compounds in the culture broth obtained from a vanitaracin A-producing fungus under various conditions. Three novel compounds (vanitaracin C, vanitaraphilone A, and 2-hydroxy-4-(hydroxymethyl)-6-methylbenzaldehyde) were isolated, and their structures were determined using spectroscopic methods (1D/2D NMR and MS). In addition, the antiviral spectrum of vanitaracin A was examined by measuring its antiviral activities against rabies virus, Borna disease virus 1, and bovine leukemia virus. This compound exhibited antiviral activity against bovine leukemia virus, which is the causative agent of enzootic bovine leukosis. The anti-bovine leukemia virus effects of other compounds isolated from the vanitaracin A-producing fungus, namely, vanitaracins B and C, vanitaraphilone A, and 2-hydroxy-4-(hydroxymethyl)-6-methylbenzaldehyde, were also evaluated. Vanitaracin B, vanitaraphilone A and 2-hydroxy-4-(hydroxymethyl)-6-methylbenzaldehyde were also found to exhibit activity against bovine leukemia virus. These findings reveal the broad-spectrum antiviral activity of the vanitaracin scaffold and suggest several candidates for the development of anti-bovine leukemia virus drugs.
