  • Title: Three new polyketides from marine-derived fungus Aspergillus glaucus HB1-19.
    Author: Sun SW, Ji CZ, Gu QQ, Li DH, Zhu TJ.
    Journal: J Asian Nat Prod Res; 2013 Sep; 15(9):956-61. PubMed ID: 23947932.
    Abstract:
    Two new benzyl derivatives, aspergentisyl A (1) and aspergentisyl B (2), as well as one new naphthoquinone derivative, aspergiodiquinone (3), together with seven known prenylated benzaldehyde derivatives (4-10) were isolated from the marine-derived fungus Aspergillus glaucus HB1-19. The structures of these compounds were characterized based on 1D and 2D NMR spectra analyses and comparison with those reported in the literature. In addition, each isolate was tested for its 1,1-diphenyl-2-picrylhydrazyl radical-scavenging property and all these compounds except compound 3 exhibited strong radical-scavenging activity.
