TAK-242 (Resatorvid), a small-molecule-specific inhibitor of Toll-like receptor (TLR) 4 signaling, inhibits the production of lipopolysaccharide-induced inflammatory mediators by binding to the intracellular domain of TLR4. IC50 value: 1.1-11 nM Target: TLR4 in vitro: In RAW264.7 cells and mouse peritoneal macrophages, TAK-242 suppressed lipopolysaccharide (LPS)-induced production of NO, tumor necrosis factor-alpha (TNF-alpha), and interleukin (IL)-6, with 50% inhibitory concentration (IC50) of 1.1 to 11 nM. TAK-242 also suppressed the production of these cytokines from LPS-stimulated human peripheral blood mononuclear cells (PBMCs) at IC50 values from 11 to 33 nM. In addition, the inhibitory effects on the LPS-induced IL-6 and IL-12 production were similar in human PBMCs, monocytes, and macrophages. TAK-242 inhibited mRNA expression of IL-6 and TNF-alpha induced by LPS and interferon-gamma in RAW264.7 cells . TAK-242 selectively bound to TLR4. The time course of the inhibitory effect of TAK-242 on inflammatory mediator production corresponded to that of the binding of TAK-242 to TLR4. TAK-242 inhibited the association of TLR4 with Toll/interleukin-1 receptor domain-containing adaptor protein (TIRAP) or Toll/interleukin-1 receptor domain-containing adaptor protein inducing interferon-β-related adaptor molecule (TRAM) in human embryonic kidney (HEK) 293 cells overexpressing TLR4, MD-2, and TIRAP or TRAM, respectively . in vivo: To evaluate the effect of blocking TLR4 on visceral nociception, TAK-242, a selective TLR4 antagonist, was administered peripherally (intravenous) and centrally (intracerebroventricular and intra-PFC) (n = 10-12/experimental group) . Intravenous administration of TAK-242 to mice 1 h be Fore LPS challenge dose-dependently inhibited LPS-induced increases in serum levels of TNF-alpha, IL-1beta, IL-6, IL-10, MIP-2, and NO metabolites. TAK-242 protected mice from LPS-induced lethality in a similar dose-dependent manner, and rescued 100% of mice at a dose of 1 mg/kg. Interestingly, TAK-242 worked quickly, and showed beneficial effects even when administered after LPS challenge .For the detailed information of TAK-242 (Resatorvid), the solubility of TAK-242 (Resatorvid) in water, the solubility of TAK-242 (Resatorvid) in DMSO, the solubility of TAK-242 (Resatorvid) in PBS buffer, the animal experiment (test) of TAK-242 (Resatorvid), the cell expriment (test) of TAK-242 (Resatorvid), the in vivo, in vitro and clinical trial test of TAK-242 (Resatorvid), the EC50, IC50,and Affinity of TAK-242 (Resatorvid), Please contact DC Chemicals.
Enpatoran (M5049) is an orally active and dual TLR7/8 inhibitor with IC50s of 11.1 nM and 24.1 nM in HEK293 cells, respectively. Enpatoran can block both innate and adaptive autoimmunity. Enpatoran is inactive against TLR3, TLR4 and TLR9. Enpatoran (M5049) can block molecule synthetic ligands and natural endogenous RNA ligands. Enpatoran (M5049) inhibits cytokine release, causing great potency in pharmacokinetic/pharmacodynamic properties.
