Water Insoluble
Ethanol Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5% DMSO 95% corn oil
0.65mg/ml Taking the 1 mL working solution as an example, add 50 μL of 13 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
0.35mg/ml Taking the 1 mL working solution as an example, add 50 μL of clarified DMSO stock solution of 7 mg/ml to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify it; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description R-7050 is a cell permeable TNF-α receptor antagonist and is 2.3-fold more selective for TNF-α-mediated signaling than for that driven by IL-1β.
Targets
TNF-α [2] IL-1β [2]
0.63 μM(EC50) 1.45 μM(EC50)
In vitro

R-7050 has a clear selectivity toward TNFα and to a slightly weaker extent toward the LPA receptor which belongs to a GPCR class over IL-1β, tyrosine kinase, or Fas receptor systems[2].
In vivo

R-7050 attenuates neurovascular injury after intracerebral hemorrhage (ICH) in mice, Up to 2h post-injury administration of R-7050 significantly reduced blood-brain barrier opening and attenuated edema development at 24h post-ICH. Neurological outcomes were also improved over the first three days after injury. In contrast, R-7050 did not reduce hematoma volume[1].

Protocol (from reference)

Animal Study:

[1]
  • Animal Models

    A mouse collagenase model of ICH (based on male CD-1 mice)

  • Dosages

    6–18 mg/kg

  • Administration
