Toll-like receptors(TLRs) are evolutionarily conserved innate immunity receptor proteins that detect pathogen-associated molecular patterns(PAMPs), danger-associated molecular patterns(DAMPs) and xenobiotic-associated molecular patterns(XAMPs), triggering inflammatory responses. TLR4 is the main receptor for bacterial lipopolysaccharide(LPS) and the accessory protein myeloid differentiation factor 2(MD-2) is responsible for ligand recognition. LPS binding induces(TLR4-MD-2-LPS)2 and TLR4/MD-2 complex dimeriztion, which activates TLR4 signaling and produce pro-inflammatory factors. The dysregulation of innate immune TLR4 signaling contributes to numerous pathological diseases. Therefore, TLR4/MD-2 is emerging as an important drug discovery target. In this review, we summarize the up-to-date discovery of TLR4 small molecule modulators and provide insights into future drug discovery, which will be interesting to colleagues major in chemical biology, medicinal chemistry, signal transduction and translational medicine.
