β-funaltrexamine (β-FNA) is a irreversible and selective μ opioid receptor antagonist that exhibits anti-inflammatory and neuroprotective effects. β-Funaltrexamine reduces TLR4 signaling, inhibits cytokine-induced iNOS activation and neuroinflammation, and ameliorates neuronal degeneration. β-funaltrexamine inhibits NF-κB signaling and chemokine expression in both human astrocytes and mice. β-funaltrexamine can be used for research on neurodegenerative diseases, such as stroke.
