IRF1-IN-2 is a small molecule inhibitor of interferon regulatory factor 1 (IRF1) that functions by reducing the binding affinity of IRF1 for the caspase-1 (CASP1) gene promoter. this inhibition subsequently suppresses critical cell death signaling pathways, such as pyroptosis, and provides robust protection against ionizing radiation-induced skin inflammatory damage in preclinical models.

| Description | IRF1-IN-2 is a small molecule inhibitor of interferon regulatory factor 1 (IRF1) that functions by reducing the binding affinity of IRF1 for the caspase-1 (CASP1) gene promoter. this inhibition subsequently suppresses critical cell death signaling pathways, such as pyroptosis, and provides robust protection against ionizing radiation-induced skin inflammatory damage in preclinical models. |
| In vitro | Pretreatment of irradiated HaCaT cells, HELF and WS1 cells with IRF1-IN-2 (20 μM, 12 h) reduced the recruitment of IRF1 to the CASP1 promoter in HaCaT cells (20 Gy) and also attenuated IRF1 activation induced by NSP-10 plasmid transfection in HELF and WS1 cells. [1] |
| In vivo | Methods: IRF1-IN-2 (100 μg/d, subcutaneous injection, irradiated every other day) was administered to mice with inflammatory skin lesions induced by 35 Gy radiation, and its effects were observed. Results: IRF1-IN-2 has a potential protective effect against inflammatory skin lesions induced by 35 Gy radiation in mice. [1] |

DMSO
| ||||||||||||||||||||||||||||||||||||
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.
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.
