TLR4 Antagonist

TLR4 Antagonists (5):

Cat. No. Product Name Effect Purity
  • HY-116213
    Sparstolonin B
    		Antagonist 99.94%
    Sparstolonin B acts as a selective TLR2 and TLR4 antagonist and selectively blocks TLR2- and TLR4-mediated inflammatory signaling. Sparstolonin B has anti-HIV and anticancer activities.
  • HY-125171
    IAXO-102
    		Antagonist 98.0%
    IAXO-102 is a TLR4 antagonist which negatively regulates TLR4 signalling. IAXO-102 inhibits MAPK and p65 NF-κB phosphorylation and expression of TLR4 dependent proinflammatory protein. IAXO-102 also prevents experimental abdominal aortic aneurysm development.
  • HY-135042
    CAY10614
    		Antagonist 98.87%
    CAY10614 is a potent TLR4 antagonist. CAY10614 inhibits the lipid A-induced activation of TLR4, with an IC50 of 1.675 μM. CAY10614 can improve survival of mice in lethal endotoxin shock model.
  • HY-P10208A
    RKH acetate
    		Antagonist 99.79%
    RKH acetate exerts protective effects against sepsis-induced death and organ damage. RKH acetate can directly bind to Toll-like receptor 4 (TLR4) and block TLR4 signal transduction in immune cells.
  • HY-178037
    TLR9 antagonist 1
    		Antagonist
    TLR9 antagonist 1 (Compound 38) is a selective TLR9 antagonist with an IC50 of 0.1  nM for hTLR9 over hTLR2/4/5/7/8. TLR9 antagonist 1 exacerbates disease symptoms with increased anti-dsDNA and anti-Sm levels in systemic lupus erythematosus (SLE) mouse models. TLR9 antagonist 1 can be used for inflammatory and immune diseases like lupus and arthritis research.
