Mangiferin is a Nrf2 activator. Mangiferin suppresses nuclear translocation of the NF-κB subunits p65 and p50. Mangiferin exhibits antioxidant, antidiabetic, antihyperuricemic, antiviral, anticancer and antiinflammatory activities.

Mangiferin is glucosylxanthone extracted from plants of the Anacardiaceae and Gentianaceae families. Mangiferin (50 μM) significantly increases Nrf2 protein accumulation in HL-60 cells, particularly in the nucleus. Mangiferin also enhances the binding of Nrf2 to an antioxidant response element (ARE), significantly up-regulates NAD(P)H:quinone oxidoreductase 1 (NQO1) expression and reduces intracellular ROS in HL60 cells. Mangiferin alone dose-dependently inhibits the proliferation of HL-60 cells. In mononuclear cells (MNCs), Mangiferin significantly relieves oxidative stress, but attenuates etoposide-induced cytotoxicity. Mangiferin is a natural phytopolyphenol that exhibits various pharmacological properties. Mangiferin is present in several plant species such as Mangifera indica, Iris unguicularis, and Anemarrhena asphodeloides. Mangiferin downregulates TNF-α-induced MMP-9 mRNA and protein expression by suppressing NF-κB activity, consequently suppressing the invasion of LNCaP cells.To assess whether Mangiferin influences the viability of LNCaP cells, MTT assay is performed 24 h after treatment with different concentrations of Mangiferin in the presence or absence of TNF-α in serum and serum-free conditions. There are no cytotoxic evident in LNCaP cells treated with up to 400 μM of Mangiferin alone under both serum and serum-free conditions. Additionally, in the presence of TNF-α (20 ng/mL), Mangiferin does not affect cell viability. Mangiferin (400 μM) treatment significantly decreases the NF-κB luciferase activity in TNF-α-stimulated LNCaP cells. Pretreatment with Mangiferin (400 μM) for 1 h significantly decreases TNF-α-induced NF-κB activity. The RT-PCR shows that Mangiferin (400 μM) significantly suppresses the TNF-α-induced MMP-9 expression in LNCaP cells.
