factor 2 (Nrf2) activation. However, it remains unclear whether cyclobakuchiols A-C induce anti-influenza A virus activity. In this study, cyclobakuchiols A, B, and C along with cyclobakuchiol D, a new artificial compound derived from cyclobakuchiol B, were synthesized and examined for their anti-influenza A virus activities using Madin-Darby canine kidney cells. As a result, cyclobakuchiols A-D were found
需要用于流感的新型抗病毒剂,其对人类构成重大威胁。环ob草酚A和B已从大叶补骨脂(Psoralea glandulosa)中分离出来,而环b草酚C已从番石榴(P. corylifolia)中分离出。环爆酚A和C之间的结构差异是由于异丙基的氧化态而引起的,这些化合物可以衍生自(+)-(S)-爆酚,一种存在于紫花苜蓿种子中的酚类异戊二烯化合物。我们以前曾报道爆裂酚诱导对映体特异性抗甲型流感病毒活性,涉及核因子红系2相关因子2(Nrf2)激活。然而,尚不清楚环爆酚AC是否诱导抗甲型流感病毒活性。在这项研究中,环爆酚A,B和C以及环爆酚D(一种由环爆酚B衍生的新型人工化合物)合成并使用Madin-Darby犬肾细胞检查其抗甲型流感病毒活性。结果,发现环爆酚AD抑制甲型流感病毒感染细胞中甲型流感病毒的感染,生长以及病毒mRNA和蛋白质表达的减少。此外,这些化合物显着降低了宿主细胞甲型流感病毒诱导的免
