RIPK1-IN-41
RIPK1-IN-41 is an orally active RIPK1 inhibitor with an IC50 of 92 nM and a KD of 106.8 nM. RIPK1-IN-41 reduces the phosphorylation level of RIPK1, inhibits necrosome formation, blocks the activation of RIPK3 and MLKL, maintains mitochondrial and lysosomal functions, preserves cell membrane integrity, and suppresses necroptosis. RIPK1-IN-41 alleviates hypothermia and multi-organ damage in a mouse model of systemic inflammatory response syndrome induced by mTNF-α. RIPK1-IN-41 is applicable to research related to systemic inflammatory response syndrome.

RIPK1 92 nM (IC50) |
RIPK1 106.8 nM (Kd) |
RIPK1-IN-41 (Compound 5e) potently inhibits purified RIPK1 kinase with an IC50 of 92 nM[1].
RIPK1-IN-41 directly binds to purified RIPK1 kinase with a K0 of 106.8 nM[1].
RIPK1-IN-41 strongly inhibits purified RIPK1, moderately inhibits purified RIPK3, and retains multi-targeted activity against several other kinases including VEGFR2, PDGFRβ, and FLT3[1].
RIPK1-IN-41 dose-dependently inhibits mTNF-α/Z-VAD-FMK-induced necroptosis in L929 cells with an EC50 of 0.45 μM[1].
RIPK1-IN-41 (0.05-1 μM) can maintain, in a dose-dependent manner, the mitochondrial integrity and lysosomal integrity of mTNF-α/Z-VAD-FMK-induced necrotic apoptosis in L929 cells, inhibit the formation of RIPK1-RIPK3 necrosomes, upregulate pMLKL activation and lysosomal translocation[1].
RIPK1-IN-41 (0.5 μM; 3-6 h) time-dependently inhibits the phosphorylation of RIPK1, RIPK3, and MLKL in mTNF-α/Z-VAD-FMK-induced necroptotic L929 cells[1].
RIPK1-IN-41 (0.05-1 μM,1 h pretreatment; 6 h necroptosis induction) reduced phosphorylation of RIPK1, RIPK3, and MLKL[1].
