从海洋海绵真菌Aspergillus sp.SCSIOXWS02F40中分离得到两个新的海星毒素(asteltoxin),命名为海星毒素E(2)和F(3),一个新的色原酮(4),以及四个已知化合物。化合物(1-7)的结构通过广泛的1D-NMR和2D-NMR谱和HRESIMS谱确定。测试所有化合物的抗病毒(H1N1和H3 N2)活性。化合物2和3显示出显著的抗H3 N2活性,其突出的IC 50值分别为6.2 ± 0.08和8.9 ± 0.3 μM。此外,化合物2还表现出对H1N1的抑制活性,IC 50值为3.5 ± 1.3 μM。
Two new asteltoxins named asteltoxin E (2) and F (3), and a new chromone (4), together with four known compounds were isolated from a marine sponge–derived fungus, Aspergillus sp. SCSIO XWS02F40. The structures of the compounds (1–7) were determined by the extensive 1D- and 2D-NMR spectra, and HRESIMS spectrometry. All the compounds were tested for their antiviral (H1N1 and H3N2) activity. Compounds 2 and 3 showed significant activity against H3N2 with the prominent IC50 values of 6.2 ± 0.08 and 8.9 ± 0.3 μM, respectively. In addition, compound 2 also exhibited inhibitory activity against H1N1 with an IC50 value of 3.5 ± 1.3 μM.
