Two new secondary metabolites from the marine-derived fungusNigrospora sphaerica

Two new secondary metabolites, (2S)-5-acetamidopentyl-2-hydroxypropanoate (1) and 2, 5, 7-trihydroxy-4-(3′-methylbut-2′-en-1′-yl) oxy-2H-naphtho [1, 8-b c] furan-9-one (2) were isolated from the marine-derived fungus Nigrospora sphaerica. The structures were established on the basis of their spectroscopic data, including 1D NMR and 2D NMR, HR-TOF-MS, and the absolute configuration of compound 1 was determined by the Mosher method.
