Appearance White solid.
Solubility Soluble in Methanol, DMSO and Ethanol 1:1 (vol:vol): >10mM.
Biological Activity

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.
Declaration Manufactured by Innaxon.
Other Product Data

Reconstitution: For a 2mM stock solution, dissolve total vial content in 661μl (1mg size) or 3,306μl (5mg size) DMSO/Ethanol (1:1) (vol:vol).

  • 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.
