“Grossamide, a representative lignanamide in hemp seed, has been reported to possess potential anti-inflammatory effects. However, the potential anti-neuroinflammatory effects and underlying mechanisms of action of grossamide are still unclear. Therefore, the present study investigated the possible effects and underlying mechanisms of grossamide against lipopolysaccharide (LPS)-induced inflammatory response in BV2 microglia cells.

This study demonstrated that grossamide significantly inhibited the secretion of pro-inflammatory mediators such as interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α), and decreased the level of LPS-mediated IL-6 and TNF-α mRNA. In addition, it significantly reduced the phosphorylation levels of NF-κB subunit p65 in a concentration-dependent manner and suppressed translocation of NF-κB p65 into the nucleus. Furthermore, grossamide markedly attenuated the LPS-induced expression of Toll-like receptor 4 (TLR4) and myeloid differentiation factor 88 (MyD88).

Taken together, these data suggest that grossamide could be a potential therapeutic candidate for inhibiting neuroinflammation in neurodegenerative diseases.”
