RIPK1-IN-34
RIPK1-IN-34 is a selective, brain-penetrant RIPK1 inhibitor (IC50 = 126.70 nM) with almost no inhibitory effect on RIPK3 (IC50 ＞ 10, 000 nM). RIPK1-IN-34 offers substantial neuroprotection by inhibiting the phosphorylation of RIPK1, RIPK3, and mixed lineage kinase domain-like pseudokinase (MLKL) within the necroptosis pathway. RIPK1-IN-34 shows the neuroprotective effect in a rat middle cerebral artery occlusion (MCAO) model. RIPK1-IN-34 can be used for the study of anti-acute ischemic stroke (AIS).

RIPK1 126.7 nM (IC50) |
RIPK1-IN-34 (Compound 9b) significantly reduces TNF-α (T), a Smac-mimetic, SM-164 (HY-15989) (S), and Z-VAD-FMK (HY-16658B) (Z)-induced apoptosis in HT-29 (EC50 = 71.61 nM) and HT-22 (EC50 = 38.45 nM) cells[1].
RIPK1-IN-34 (0.78-400 nM, 24 h) effectively counters the TSZ-induced changes and approximates the untreated control group's condition in HT-29, U937, L929 and HT-22 cells[1].
RIPK1-IN-34 (1, 10, 100 nM, 4.5 h) is effective in protecting the cells from necroptosis in L929 cells[1].
Compound RIPK1-IN-34 (0-1000 nM, 4.5 h) dose-dependently inhibits the phosphorylation of RIPK1, RIPK3, and MLKL in L929 cells[1].

RIPK1-IN-34 (78.4-160 mg/kg, i.p., two intraperitoneal injections, one hour apart) does not cause acute toxicity at the dose tested in C57BL/6 mice, and its LD50 exceeds 160 mg/kg, indicating that it has a high safety profile[1].

-
Animal Model:SPF grade male SD rats (180-200 g) were used to construct a middle cerebral occlusion model[1].
-
Dosage:0.5 mg/kg, 1.5 mg/kg, 4.5 mg/kg
-
Administration:I.v., administered intravenously once 0.5 hours before modeling, and again after reperfusion, for a total of two administrations
-
Result:Significantly improved neurological outcomes 24 h post-operation, with reductions in scores exhibiting a dose-dependent trend: low dose (5.20), medium dose (5.09), and high dose (3.82).
Significantly reduced infarct volumes across all treatment groups in a dose-responsive manner: low dose (20.60), medium dose (18.32), and high dose (16.51).
Diminished MDA, TNF-α, and IL-1β levels while slightly increasing SOD levels.
-
Animal Model:SPF grade male C57BL/6 mice (aged 6-8 weeks, weighing 18-22 g)[1].
-
Dosage:160 mg/kg, 112 mg/kg, 78.4 mg/kg
-
Administration:I.p., two intraperitoneal injections, one hour apart
-
Result:No abnormal behaviors or deaths were observed, and the body weight of mice in all groups steadily increased over 7 days with no significant differences.
