Description

MD2-IN-1 is an inhibitor of Myeloid differentiation protein 2 (MD2) with a KD of 189  μM for the recombinant human MD2 (rhMD2).

IC50 & Target

KD: 189 μM (rhMD2)[1]
In Vitro

Myeloid differentiation protein 2 (MD2) is a co-receptor of TLR4. Among those derivatives, MD2-IN-1 (compound 20) shows the strongest inhibitory effect on LPS-induced expression of both TNF-α and IL-6. Compare to the vehicle, LPS alone largely increases the amount of TLR4/MD2 complex, while pretreatment with MD2-IN-1 inhibits the increase of TLR4/MD2 complex to the vehicle level. SPR analysis shows that MD2-IN-1 exhibits recognizable binding to rhMD2 protein in a dose-dependent manner, with a KD value of 189 μM, while the KD value of xanthohumol binding to MD2 is 460 μM. Pre-treatment with different doses of MD2-IN-1 dose-dependently reduces FITC-LPS binding to MD2 in cell surface membranes, with a 65% inhibition at 10 μM in terms of mean fluorescence intensity. Pretreatment with MD2-IN-1 also dose-dependently blocks LPS-induced MAPK phosphorylation in the MPMs[1].

In Vivo

Administration of MD2-IN-1 evidently reduces the LPS-induced increase in protein concentrations in BALF. The lung wet/dry weight ratio is markedly higher in the LPS-treated group than the control group, and MD2-IN-1 treatment reduces LPS-induced pulmonary edema. LPS also causes observable lung histopathologic changes, including areas of inflammatory infiltration, hemorrhage, interstitial edema, thickening of the alveolar wall, and lung tissue destruction. These histopathological changes are ameliorated in the MD2-IN-1 treatment group[1].

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 3.25 mg/mL (9.07 mM); Clear solution

    This protocol yields a clear solution of ≥ 3.25 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (32.5 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.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 3.25 mg/mL (9.07 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 3.25 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (32.5 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Cell Assay
[1]

Mouse RAW264.7 macrophages are starved for 3 h before experimentation. Cells are incubated with or without FITC-LPS (50 μg/mL) in the presence or absence of MD2-IN-1 (0.1, 1 and 10 μM) for 30 min. After incubation, macrophages are fixed with paraformaldehyde for 10 min at 4°C and washed with PBS before being analyzed by flow cytometry[1].

Animal Administration
[1]

Male Sprague Dawley (SD) rats are randomly divided into three groups, designated “control” (5 rats, only receive the vehicle of 0.9% saline), “LPS” (7 rats, receive 5 mg/kg LPS alone) and “MD2-IN-1 (20) + LPS” (6 rats, receive both MD2-IN-1 and 5 mg/kg LPS). Prior to LPS-induced Acute lung injury (ALI), the MD2-IN-1+LPS group rats are treated intragastrically with MD2-IN-1 at a dosage of 20 mg/kg/day continuously for one week. Under ether anesthesia, all the rats are exposed their trachea and challenged with intratracheal instillation of 50 μL of LPS, while the control group challenged with intratracheal instillation of 50 μL of 0.9% saline. Rats are then euthanized with ketamine after 6 h of LPS induction[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
