摘要	Five new diterpenes, including four new hydroazulenes, (8R,11R)-8, 11- diacetoxypachydictyol A (1), (8R,11R) -6-O-acety1-8- acetoxy-11-hydroxypachydictyol A (2), (8R,11S)-8-acetoxy-11-hydroxypachydictyol A (3), and (8R,11S)-6-O-acety1-8,11-dihydroxypachydictyol A (4), and a secohydroazulene derivative, named 7Z-7,8-seco-7,11-didehydro-8-acetoxypachydictyol A (5), were isolated from a South China Sea collection of a Dictyota sp. nov. brown alga, together with five known analogues (6-10). Structure elucidation was achieved by extensive spectroscopic analysis and comparison with reported data. All compounds showed potent antioxidant effects against H2O2-induced oxidative damage in neuron-like PC12 cells at a low concentration of 2 mu M. The antioxidant property of dictyol C (9) was associated with activation of the Nrf2/ARE signaling pathway; it also showed neuroprotective effects against cerebral ischemia-reperfusion injury (CIRI) in a rat model of transient middle cerebral artery occlusion. As such, hydroazulene diterpenes could serve as lead structures for the development of novel neuroprotective agents against CIRI.
