Isosulochrin xanthone and isosulochrin depsidone heterodimers from the endophytic fungus Colletotrichum sp. NF02092
In this study, we isolated and characterized two polyketides (1 and 2), along with reported depsidone derivative (3) from fermentation broth of the marine fish-derived endophytic fungus Colletotrichum sp. NF02092. The structures of 1 and 2 were deduced on the basis of comprehensive analysis of HRESIMS and NMR spectroscopic data. Both compounds are heterodimers formed by the fusion of the core structure isosulochrin with a xanthan (1) and a depsidone (2), respectively. However, neither 1 nor 2 exhibited significant antimicrobial activity or cytotoxic activities.
