RIPK1-IN-42
RIPK1-IN-42 is an orally active RIPK1 inhibitor with a Kd of 21 nM. RIPK1-IN-42 inhibits the phosphorylation of RIPK1, suppresses the phosphorylation of downstream RIPK3 and MLKL, blocks necrosome formation, and inhibits necroptosis. RIPK1-IN-42 alleviates hypothermia, suppresses the elevation of pro-inflammatory cytokine levels, and reduces organ damage. RIPK1-IN-42 can be used for the research of systemic inflammatory response syndrome.

RIPK1-IN-42 (Compound W-1) (0.002441-0.3125 μM; 6 h) potently inhibits necroptosis in HT-29 cells induced by TNF-α, SM-164 (HY-15989) and Z-VAD-FMK (HY-16658B) (TSZ), with an EC50 of 38.46 nM[1].
RIPK1-IN-42 (0.1-12.8 μM; 14 h) effectively inhibits TNF-α-, Cycloheximide (HY-12320)- and Z-VAD-FMK (TCZ)-induced necroptosis in HT-29 cells in vitro in a dose-dependent manner[1].
RIPK1-IN-42 (4.6875-600 nM; 10 h) effectively inhibits TSZ-induced necroptosis in U937 cells in vitro in a dose-dependent manner[1].
RIPK1-IN-42 (6.25-400 nM; 2-6 h) inhibits TSZ-induced phosphorylation of RIPK1, RIPK3 and MLKL in HT-29 cells in a time- and dose-dependent manner[1].
RIPK1-IN-42 (400 nM; 6 h) blocks TSZ-induced necrosome formation in HT-29 cells[1].
RIPK1-IN-42 (24 h) does not inhibit cycloheximide-induced apoptosis in HT-29 cells[1].
RIPK1-IN-42 exhibits low cytotoxicity in HT-29 cells, with a CC50 greater than 100 μM[1].

Animal Model:C57BL/6J mice (female)[1]
-
Dosage:10 mg/kg; 20 mg/kg; 30 mg/kg
-
Administration:p.o.; single dose 1 hour pre-challenge
-
Result:Attenuated mTNF-α/Z-VAD-FMK-induced hypothermia, with body temperatures gradually restoring to normal levels over 9 hours across all tested doses.
Achieved 40% survival at 10 mg/kg, 60% survival at 20 mg/kg, and 90% survival at 30 mg/kg.
Significantly suppressed serum elevation of pro-inflammatory cytokine interleukin-6 (mIL-6) induced by TNFα challenge.
Reduced serum levels of organ damage biomarkers (lactate dehydrogenase, aspartate aminotransferase, creatinine, blood urea nitrogen) to levels closer to healthy animals.
Attenuated histologic signs of injury (inflammatory cell infiltration, tissue disorganization, cellular damage) in the heart, liver, and kidneys.
