MD2-TLR4-IN-1
Based on 1 publication(s) in Google Scholar
MD2-TLR4-IN-1 is a myeloid differentiation protein 2/toll-like receptor 4 (MD2-TLR4) complex antagonist. MD2-TLR4-IN-1 inhibits Lipopolysaccharides (HY-D1056) (LPS)-induced expression of TNF-α and IL-6 in macrophages with IC50 values of 0.89 μM and 0.53 μM, respectively. MD2-TLR4-IN-1 can be used for the study of acute lung injury (ALI).

Biological Activity
|
TLR4 |
MD2-TLR4-IN-1 (compound 22m) exerts its anti-inflammatory activity by inhibiting NF-κB in RAW264.7 macrophages[1].
MD2-TLR4-IN-1 is directly bound to the MD2-TLR4 complex and disrupted MD2-TLR4 activation[1].
MD2-TLR4-IN-1 suppresses the NF-κB p65 subunit nuclear levels in LPS-induced macrophages[1].
MD2-TLR4-IN-1 binds to recombinant MD2 and TLR4 proteins with Kd values of 185 and 146 μM, respectively, while it does not interact with the intracellular adaptor protein MyD88[1].
MD2-TLR4-IN-1 significantly inhibits dimerization of the MD2-TLR4
complex in LPS-activated mouse primary macrophages (MPMs)[1].

Animal Model:Male C57BL/6 mice (18-22 g) injectied intraperitoneally with LPS (20 mg/kg)[1].
-
Dosage:5 mg/kg, 10 mg/kg
-
Administration:Tail vein injection; once; 15 min before LPS injection
-
Result:Effectively reduced airspace inflammation and amended the tissue structure of pulmonary lobules.
Significantly decreases LPS-induced myeloperoxidase (MPO) activity. Reduced LPS-induced serum TNF-α levels.
Decreased the mRNA levels of TNF-α, IL-6, IL-1β, IL-12, and IL-33 in lung tissues. In addition, COX-2 mRNA levels were also reduced.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (4.94 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
