产品介绍
3',4'-Dimethoxyflavone 是一种亲脂性黄酮,可分离自黄花九轮草 (Primula veris) 的叶子。3',4'-Dimethoxyflavone 可减少PARP的合成和积累,保护皮质神经元免受Parthanatos 通路诱导的细胞死亡。3',4'-Dimethoxyflavone 在人乳腺癌细胞中也是一种芳香烃受体 (aryl hydrocarbon receptor) 拮抗剂。3',4'-Dimethoxyflavone 能促进人体造血干细胞增殖。具有多种生物活性,包括抗氧化、抗癌、抗炎、抗动脉粥样硬化、降血脂和神经保护或神经营养作用。
生物活性

3',4'-Dimethoxyflavone is a lipophilic flavone, can be isolated from the leaves ofPrimula veris. 3',4'-Dimethoxyflavone can reduce the synthesis and accumulation ofPARPand protect cortical neurones against cell death induced by Parthanatos. 3',4'-Dimethoxyflavone is also anaryl hydrocarbon receptorantagonist in human breastcancercells. 3',4'-Dimethoxyflavone can promote the proliferation of human hematopoietic stem cells. 3',4'-Dimethoxyflavone has various biological activities, including antioxidant, anti-cancer, anti-inflammatory, anti-atherogenic, hypolipidaemic, and neuroprotective or neurotrophic effects[1][2][3][4].

体外研究
(In Vitro)

3',4'-Dimethoxyflavone (10 and 20 μM) has protection against the reduction in SH-SY5Y viability induced byMethylnitronitrosoguanidine(MNNG) (HY-128612)[2].
3',4'-Dimethoxyflavone (6.25-25 μM) decreases the levels of PAR induced by MNNG in HeLa cells[2].
3',4'-Dimethoxyflavone (12.5, 25, 50 and 100 μM; 15-20 h) reduces cortical neuronal death induced by exposure toNMDA(HY-17551)[2].
3',4'-Dimethoxyflavone (0.1-10 μM; 24 h) exhibits significant inhibition of 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD)-induced EROD activity in MCF-7 and T47D cells[3].
3',4'-Dimethoxyflavone inhibits AhR-dependent CYP1A1 induction and AhR-mediated inhibition of estrogen-induced gene expression in T47D and MCF-7 breast cancer cells[3].
3′,4′-Dimethoxyflavone (2.5 μM; 7 days) promotes the proliferation of human hematopoietic stem cells[4].
