关键词: Diphenyl ethers Phomopsis fukushii anti-MRSA activity

摘要:
Three new diphenyl ethers (1-3), together with four known isopentylated diphenyl ethers derivatives (4-7), were isolated from the fermentation products of an endophytic fungus Phomopsis fukushii. Their structures were elucidated by spectroscopic methods, including extensive 1D and 2D NMR techniques. Compounds 1-3 were evaluated for their anti-methicillin-resistant Staphylococcus aureus (anti-MRSA) activity. The results revealed that compounds 1 and 2 showed strong inhibitions with inhibition zone diameters (IZD) of 20.2 +/- 2.5mm and 17.9 +/- 2.2mm, respectively. Compound 3 also showed good inhibition with IZD 15.2 +/- 1.8mm. The IZD data of compound 1 is close to that of positive control with IZD 21.9 +/- 2.1mm.
