摘要 Toll样受体(Toll-like receptors,TLRs)是进化保守的天然免疫模式识别受体,能够识别外源的病原菌相关分子模式(Pathogen-associated molecular patterns,PAMPs)、内源的损害相关分子模式(Damage-associated molecular patterns,DAMPs)和异源物相关分子模式(Xenobiotic-associated molecular patterns),诱导炎症免疫反应。其中,TLR4(Toll-like receptor 4)是目前研究最为广泛的Toll样受体之一,TLR4是脂多糖(lipopoiysaccharide,LPS)的主要受体,LPS激活的TLR4信号通路在炎症信号的传递中发挥着重要作用,而此信号转导需要通过LPS与TLR4及其附属蛋白髓样分化因子2(myeloid differentiation factor 2,MD-2)的相互作用来实现。因此,TLR4/MD-2成为炎症反应和免疫调控最重要的研究热点。本文综述靶向TLR4/MD-2的小分子激动剂和抑制剂的研究进展,以进一步理解TLR4小分子调节剂与其相互作用的复杂性,帮助靶向TLR4/MD-2的免疫调节剂药物发现。 Toll-like receptors ( TLRs ) are evolutionarily detect pathogen-associated molecular patterns (PAMPs) , conserved innate immunity receptor proteins that 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, molecule modulators and provide insights into future major in chemical biology, medicinal chemistry, we summarize the up-to-date discovery of TLR4 small drug discovery, which will be interesting to colleagues signal transduction and translational medicine.
