**Background**
Neuroinflammation is a critical process involving the activation of microglia, the resident immune cells of the central nervous system. When activated by stimuli such as lipopolysaccharides (LPS), microglia release various pro-inflammatory mediators, including nitric oxide (NO), which can lead to neuronal damage and the progression of various neurodegenerative diseases. Consequently, identifying potent inhibitors of microglia-mediated inflammation is essential for developing therapeutic strategies to protect the brain from inflammatory injury. In this context, we will introduce a neolignan with potent anti-neuroinflammatory properties – Futoquinol.
**Definition**
Futoquinol is a neolignan isolated from the dried aerial parts of Piper kadsura (Piperaceae) that potently inhibits NO production in microglia cells.
**In Vitro Studies**
Regarding the Futoquinol description, this compound belongs to the phenylpropanoids classification and possesses a molecular weight of 354.40 with the chemical Futoquinol Formula of C21H22O5. In terms of Futoquinol biological activity, the compound has demonstrated significant anti-neuroinflammatory effects in cellular models. Specifically, Futoquinol in vitro studies using LPS-activated BV-2 cells, a mouse microglia cell line, revealed that the compound potently inhibits the production of nitric oxide. The inhibitory activity was assessed using the Griess reagent method after 24 hours of treatment, yielding an IC50 value of 16.8 μM. These results suggest that Futoquinol can effectively suppress the inflammatory response in microglia. In conclusion, Futoquinol is a neolignan that exhibits potent anti-neuroinflammatory activity by inhibiting NO production in BV-2 microglia cells.
