“…These results have drawn the attention of both pharmaceutical and natural product chemists. In our search for new bioactive natural products from marine fungi in the South China Sea, we have found several bioactive compounds, including anthraquinone derivatives, cytochalasins, lumazine peptides, benzopyrans, stemphol sulfates, triterpenes, and α -pyrone derivatives [7,8,9,10,11,12,13]. Our previous investigation on the endophytic fungus Penicillium citrinum has resulted in the discovery of one new benzopyran derivative (2 R *,4 R *)-3,4-dihydro-5-methoxy-2-methyl-2H-1-benzopyran-4-ol [10].…”
