IAXO-103 (CD14/TLR4 Antagonist) (synthetic)
|MW||755.98g/mol (iodide salt)|
|Purity Chemicals||≥98% (TLC)|
|Solubility||Soluble in Methanol, DMSO and Ethanol 1:1 (vol:vol): >10mM.|
Described to interfere with human, rat and mouse TLR4/CD14 signaling, other species not tested. Optimal working concentration depends upon the type, purity and concentration and of TLR4 ligand, carrier protein such as LPS-binding protein (LBP), soluble and membrane-bound CD14, the presence of TLR4 co-receptors (e.g. CD36) as well as on type and time of read-out (e.g. cytokine measurement in cell culture supernatant) or the biological outcome of in vivo experiments and therefore needs to be determined for each application. Recommended starting concentration: in vitro: 5μM, in vivo (rodent): 3mg/kg.
|Identity||Determined by NMR and MS.|

|Product Specification Sheet|
- CD14/TLR4 antagonist. Inhibitor of sterile inflammation.
- Synthetic TLR4/CD14 ligand with TLR4 modulating activities in vitro, and conferring protection against TLR4/CD14-mediated tissue damage and inflammation in vivo. Useful to explore CD14- dependent and TLR4-independent pathways and TLR4 activation by endogenous ligands (e.g. hyaluronic acid oligosaccharides, oxLDL, HMGB1) in sterile inflammation. Shown to inhibit neuropathic pain, secondary necrosis of acute drug-induced liver failure and vascular inflammation, and abdominal aortic aneurysm by blocking non-hematopoietic TLR4 signaling. Useful tool, where inhibition of sterile (auto-) inflammation is desired, without compromising TLR4’s key role in the defense of pathogens.
