Inhibition of microglial activation using phytochemicals may be a potential candidate for the prevention of neurodegenerative diseases caused by neuroinflammation and oxidative stress. The goal of this study was to investigate the protective role of Biochanin A on lipopolysaccharide (LPS)-stimulated BV2 microglial cells. BV2 microglial cells were treated with LPS in the presence and absence of Biochanin A.For this aim, nitric oxide production, nuclear factor kappa B (NF-κB), tumor necrosis factor alpha (TNF-α), interleukin-1 beta (IL-1β), IL-6, Prostaglandin E2 (PGE2), and reactive oxygen species (ROS) levels, inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), myeloid differentiation factor-88 (MyD88), and toll like receptor-4 (TLR-4) protein expressions, Akt and ERK1/2 phosphorylation levels were measured.Biochanin A pretreatment resulted in significant and concentration-dependently reduced the LPS-induced production of nitric oxide, NF-κB p65, TNF-α, IL-1β, IL-6, PGE2, and ROS compared to the untreated group. Biochanin A prophylaxis exerted an anti-inflammatory effect by suppressing iNOS, COX-2, MyD88, and TLR-4 protein expressions and Akt and ERK1/2 pathway activation.Taken together, these results show that Biochanin A exerts antioxidant and anti-inflammatory activities, thus may be beneficial for preventing neurodegenerative diseases mediated by microglial cells.
