Benzoquinone and furopyridinone derivatives from the marine-derived fungus Talaromyces sp. MCCC 3A01752

Two new compounds, compounds 1 and 2, were obtained from the culture of a marine-derived fungus Talaromyces sp. MCCC 3A01752, together with 13 known compounds (3-15). Their structures were elucidated based on detailed analysis of NMR, HRESIMS, ECD spectra and OR value. Compound 1 exhibited antibacterial potential against Staphylococcus aureus with a MIC value of 100 μM and cytotoxic activity against gastric cancer cell line MKN1 with a IC₅₀ value of 78.0 μM.
