| 产品描述: | 3',4'-Dihydroxyflavone 是一种口服有效的抗氧化剂。3',4'-Dihydroxyflavone 抑制 NF-κB、JAK1/STAT1、AP-1、IRF3 及 MAPK/MEK/ERK 通路,同时激活 Nrf2 并减少 Keap1,发挥抗炎与抗氧化作用。3',4'-Dihydroxyflavone 抑制 NO、PGE2、促炎细胞因子和 ROS 生成,上调 GSH,并激活 KATP 通道、腺苷 A3 和 GABAA 受体。3',4'-Dihydroxyflavone 抑制 PPARγ 表达与脂肪生成分化,诱导成骨分化;同时抑制 5-脂氧合酶 (5-lipoxygenase) 和黄嘌呤氧化酶 (xanthine oxidase),弱抑制 PARP1,清除 DPPH 和超氧自由基。3',4'-Dihydroxyflavone 可用于周围神经损伤、感染性休克、肥胖、甲型流感病毒感染、不孕症和糖尿病并发症的研究。 |
