Analysis of binding site for the novel small‐molecule TLR4 signal transduction inhibitor TAK‐242 and its therapeutic effect on mouse sepsis model

Abstract

TAK-242 suppressed TLR4 signalling by binding directly to a specific amino acid Cys747 in the intracellular domain of TLR4. When co-administered with antibiotics, TAK-242 showed potent therapeutic effects in an E. coli-induced sepsis model using BCG-primed mice. Thus, TAK-242 may be a promising therapeutic agent for sepsis.
