Catalog No. T83895Cas No. 65974-52-9
Alias NCI-126224, NCI126224
NCI 126224 is a Toll-like receptor 4 (TLR4) antagonist that selectively inhibits nitric oxide production induced by the TLR4 agonist LPS in RAW 264.7 macrophages (IC50 = 0.31 µM), while exhibiting weaker effects against the TLR7/8 agonist R-848, TLR1/2 agonist Pam3CSK4, and TLR3 agonist poly(I:C). NCI 126224 also inhibits FSL-1-induced NO production at 0.6 µM and suppresses LPS-induced NF-κB activity in BV-2 glial cells, while reducing IL-1β and TNF-α levels in RAW 264.7 cells (IC50s of 5.92 and 1.54 µM, respectively). 0.42, and 1.54 µM, respectively), demonstrating its significant value in studies of inflammatory and innate immune signaling pathways.

| In vivo | Structurally related arylidene malonate derivatives developed from the NCI 126224 scaffold exhibit anti-inflammatory activity in vivo. In a mouse model of xylene-induced ear edema, optimized analogues such as Compound 3e reduced swelling and inflammation in a dose-dependent manner [1]. |

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:
For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Stock Solution Preparation:
Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
Preparation of the In Vivo Formulation:
1) Add 100 μL of the DMSO stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.
