GRAPHICAL ABSTRACT

ABSTRACT

Chemical investigation of the EtOAc extract of a deep-sea-derived fungus Penicillium thomii Maire YPGA3 cultured on rice solid medium led to the isolation of three new chromone analogs, named penithochromones U-W (1-3), along with six known compounds (4-9). The structures were determined by extensive analyses of spectroscopic data (NMR and HRESIMS data). Compounds 1-3 are 5,7-dioxygenated chromone analogs bearing an aliphatic acid side chain. All isolated compounds were inactive toward the a-glucosidase at the concentration of 200 mM.
