Secondary metabolites from the mangrove endophytic fungus Penicillium sp. (SBE-8).
A new metabolite, 7-hydroxyjanthinone (1), was isolated from the mangrove endophytic fungus Penicillium sp. (SBE-8), together with two known compounds, janthinone (2) and citrinin (3). The structures of these compounds were identified by spectroscopic methods. Compounds 1 and 2 showed no cytotoxicity against KB and KBv cell lines when tested by the MTT method, but compound 3 was weakly active.
