生物活性

3',4'-Dimethoxyflavone is a lipophilic flavone, can be isolated from the leaves of Primula veris. 3',4'-Dimethoxyflavone can reduce the synthesis and accumulation of PARP and protect cortical neurones against cell death induced by Parthanatos. 3',4'-Dimethoxyflavone is also an aryl hydrocarbon receptor antagonist in human breast cancer cells. 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].

體外研究
(In Vitro)

3',4'-Dimethoxyflavone (10 and 20 μM) has protection against the reduction in SH-SY5Y viability induced by Methylnitronitrosoguanidine (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 to NMDA (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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
