T6167923 B

T6167923 is a potent, selective inhibitor of MyD88-dependent signaling pathways. It achieves this by directly binding to the Toll/IL1 receptor (TIR) domain of MyD88, preventing MyD88 homodimer formation. Subsequently, T6167923 impedes NF-κB driven Staphylococcus enterotoxin AP (SEAP) activity and boasts improved anti-inflammatory effects, with IC50s values of 2.7 μM for IFN-γ, 2.9 μM for IL-1β, and 2.66 μM each for IL-6 and TNF-α, demonstrating its efficacy across multiple inflammatory mediators .
