Guo Z, Cheng F, Zou K, Wang J, She Z, Lin Y. Secondary metabolites from the mangrove endophytic fungus Penicillium sp. (SBE-8). Nat Prod Commun. 2009;4(11):1481-3.
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.
