We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Dibenzo-alpha-pyrones from the endophytic fungus Alternaria sp. Samif01: isolation, structure elucidation, and their antibacterial and antioxidant activities.[Pubmed:27388053]
Nat Prod Res. 2017 Feb;31(4):387-396.
The EtOAc extract of the liquid fermentation of Alternaria sp. Samif01, an endophytic fungus obtained from Salvia miltiorrhiza Bunge, showed antibacterial activity against several tested bacterial pathogens. Fractionation of this extract led to the isolation of seven dibenzo-alpha-pyrones (1-7), including one new compound, 2-acetoxy-2-epi-altenuene (1) and one new natural product, 3-epi-dihydroaltenuene A (2). The structures of the new metabolites were elucidated by comprehensive analysis of the spectroscopic data including (1D, 2D) NMR and HRESIMS, while the absolute configuration of 1 was determined by TDDFT-ECD computation. Altenuisol (5), 4-hydroxyalternariol-9-methyl ether (6), and alternariol (7) showed inhibitory activities against the tested bacteria with minimum inhibitory concentration values in the range of 86.7-364.7 muM. A preliminary structure-antibacterial activity relationship was discussed. In addition, compounds 2, 5 and 6 displayed promising antioxidant effects using DPPH and hydroxyl radical assays. The cytotoxicity of the isolated compounds was evaluated as well.
