Bioactivity | IRF1-IN-2 (Compound I-19) is an IRF1 inhibitor. IRF1-IN-2 decreases the recruitment of IRF1 to the promoter of CASP1. IRF1-IN-2 inhibits cell death signaling pathway (i.e., cleavage of Caspase 1, GSDMD, IL-1 and PARP1; inhibits the Pho of TKB1, upregulates GPX4 and downregulates FACL4). IRF1-IN-2 has a protective effect on ionizing radiation-induced inflammatory skin injury[1]. |
