Secondary metabolites of Aspergillus fumigatus ZNM2-3 from karst cave sediment
摘要
Abstract
The secondary metabolites of Aspergillus fumigatus ZNM2-3 isolated from the sediment of Nali Karst Cave in Shangsi County,Fangchenggang,Guangxi were studied.The secondary metabolites were isolated and purified by normal phase silica gel column chromatography and high-performance liquid chromatography.The structures were identified by electrospray ionization mass spectrometry(ESI-MS),NMR and other methods.The cytotoxic activity and α-glucosidase inhibitory activity of the compounds were determined,and the active compounds were verified by molecular docking.In total,13 compounds were isolated from Aspergillus fumigatus ZNM2-3.Of which compound 6 had cytotoxic activity;compounds 8 and 12 had certain inhibitory effects on α-glucosidase,with IC50 values of 9.46 μmol/L and 10.17 μmol/L,respectively.Molecular docking results showed that both of these two compounds could bind α-glucosidase in the form of hydrogen bonds,thereby inhibiting the degradation of the substrate by the enzyme.关键词
