Abstract:
A new chromone derivative, aspergione A (1), along with seven known metabolites, was isolated from a mangrove endophytic fungus, Aspergillus sp. GXNU-B1, which was collected from mangrove Acanthus ilicifolius L. Their structures and the absolute configuration of 1 were elucidated based on the analysis of HR-ESI-MS, NMR, and ECD calculation. Compounds 1-8 were evaluated for their anti-inflammatory effects on the production of nitricoxide (NO). Compounds 1 and 8 have potent inhibitory effects against NO production in activated macrophages with IC50 values of 38.26 and 44.30 μM, respectively.
