Metabolomics of the wild mushroom Gymnopilus imperialis (Agaricomycetes, Basidiomycota) by UHPLC-HRMS/MS analysis and molecular network
2022, Fungal BiologyCitation Excerpt :Thus, the crude methanolic extract, partitions phases, and fractions of the wild mushrooms G. imperialis were dereplicated. According to the literature, some species of Gymnopilus can biosynthesize styrylpyrones such as hispidin and bisnoryangonin with reported antioxidant and antitumor activities (Hatfield and Brady, 1969; I.-K. Lee et al., 2008). In addition to styrylpyrones, the occurrence of oligoisoprenoids, molecules that contain between 45 and 60 atoms of carbon, were also reported as major metabolites in G. spectabilis s. auct (I.-K. Lee et al., 2008).
Drimane sesquiterpenoids from cultures of the basidiomycete Gymnopilus sp. BCC 19384
2020, Phytochemistry LettersCitation Excerpt :Gymnopilus is a genus of gilled mushroom within the fungal family Hymenogastraceae. Although over 250 species have been described, extensive chemical investigations have been done only for the big-laughter mushroom, Gymnopilus spectabilis (currently named as G. junonius): polyisoprenepolyols such as gymnoprenols and gymnopilins (Aoyagi et al., 1983; Nozoe et al., 1983a,b; Tanaka et al., 1993), and styryl 2-pyranones (Hatfield and Brady, 1969; Lee et al., 2008). There are many other chemically unexplored or rarely investigated species.

2009, TetrahedronCitation Excerpt :Two known styryl-pyran-2-ones, 5,6-dehydrokawain73 (62), and 4′-hydroxy-5,6-dehydrokawain74 (68), have been isolated from ethanolic extracts of the seeds of Alpinia blepharocalyx, and the latter (68) has shown significant antiproliferative activity against murine colon 26-L5 carcinoma (ED50: 20.7 μM) and human HT-1080 fibrosarcoma (ED50: 20.1 μM) cells.75 Two new dihydrostyrylpyrones (70 and 71) and a styrylpyrone (72), together with a known styrylpyrone (69), have been isolated from the ethyl acetate-soluble fraction of an aqueous ethanol (1:4) extract of the herb Polygala sabulosa,76 which is used as a topical anaesthetic in folk medicine. 5,6-Dihydro-2-pyranones, dihydromethysticin 73 and methysticin 74, have been reported from the root extracts of Kava.77
