Polyketide and Sesquiterpenediol Metabolites from a Marine-Derived Fungus

Bulletin of the Korean Chemical Society, 2004
Marine microorganisms such as bacteria and fungi inhabit virtually any environment in the sea, and they are rich sources of chemically and biologically diverse compounds. In our search for bioactive compounds in marine microorganisms, two new halogenated alkenoates, methyl 2,4dibromo-5-oxo-2-decenoate (1) and methyl 2,4-dibromo-5oxo-3-decenoate (2 ...

Citrinin Derivatives from the Marine-Derived Fungus Penicillium citrinum

Chemical and Pharmaceutical Bulletin, 2011
Three new citrinin derivatives, penicitrinols C, D, and E (1-3), along with two known compounds, citrinin (4) and decarboxydihydrocitrinone (5), were isolated from Penicillium citrinum. Their structures were determined by spectroscopic methods and X-ray diffraction analysis. Compounds 1 and 3 demonstrated weak cytotoxicity against the HL-60 cell line.
