从海绵真菌Trichoderma sp. HPQJ-34的培养物中分离到一个新的环戊烯酮5-羟基环戊烯酮(1),以及三个已知化合物ar-turmerone(2),citreoisocoumarin(3)和6-O-甲基-citreoisocoumarin(4)。化合物1-4的结构用综合光谱分析进行了表征。1的绝对构型通过将电子圆二色性(ECD)光谱与用于报道的类似物环青霉酮(5)的文献值进行比较来确定,环青霉酮(5)在本研究中未分离。化合物1具有清除2,2-二苯基-1-苦肼基自由基和降低β-淀粉样蛋白(Aβ)的作用。此外,1显着降低过氧化氢诱导的神经毒性在SH-SY 5 Y细胞。化合物1为新发现的环戊烯酮,具有一定的抗氧化、抗A β纤维化和神经保护作用,可能是一种良好的自由基清除剂。
A new cyclopentenone, 5-hydroxycyclopeni cillone (1), was isolated together with three known compounds, ar-turmerone (2), citreoisocoumarin (3), and 6-O-methyl-citreoisocoumarin (4), from a culture of the sponge-derived fungus Trichoderma sp. HPQJ-34. The structures of 1–4 were characterized using comprehensive spectroscopic analyses. The absolute configuration of 1 was determined by comparison of electronic circular dichroism (ECD) spectra with literature values used for the reported analogue, cyclopenicillone (5), which was not isolated in this research. Compound 1 was shown to scavenge 2,2-diphenyl-1-picrylhydrazyl free radicals, and decrease β-amyloid (Aβ) fibrillization in vitro. Moreover, 1 significantly reduced H2O2-induced neurotoxicity in SH-SY5Y cells. These findings suggested that compound 1, a newly discovered cyclopentenone, has moderate anti-oxidative, anti-Aβ fibrillization properties and neuroprotective effects, and might be a good free radical scavenger.
