– TLR4/NF-κB-IN-1 (Compound 7x) is an orally bioavailable inhibitor targeting the TLR4/NF-κB signaling pathway, with anti-inflammatory properties and the ability to cross the blood-brain barrier. It can alleviate LPS-induced acute neuroinflammation in mice and downregulate the protein expression of TLR4, P-NF-κB, and P-IκB-α.
