RIPK1/RIPK3-PPI-IN-1 is an orally active dual-target inhibitor of RIPK1/RIPK3, with a Kd value of 2.4 nM for RIPK1 and 24 nM for RIPK3. RIPK1/RIPK3-PPI-IN-1 inhibits the phosphorylation of RIPK1, RIPK3 and MLKL, thereby suppressing necroptosis. RIPK1/RIPK3-PPI-IN-1 restores body temperature, improves survival rate, and reduces IL-1β/IL-6 levels in serum and multiple organs of Mus musculus, thus alleviating TNF-α-induced systemic inflammatory response syndrome. RIPK1/RIPK3-PPI-IN-1 can be used in research related to systemic inflammatory response syndrome.

In Vitro

RIPK1/RIPK3-PPI-IN-1 (Compound 10) (6.7 nM; 16 h) potently suppresses necroptosis in human HT-29 cells induced by TSZ (co-induced by TNF-α, a Smac mimetic, and the pan-caspase inhibitor z-VAD-fmk (HY-16658B)), with an EC50 of 6.7 nM[1].
RIPK1/RIPK3-PPI-IN-1 (5-20 nM; 6 h) dose-dependently inhibits TSZ-induced phosphorylation of RIPK1, RIPK3 and MLKL in human HT-29 cells[1].
RIPK1/RIPK3-PPI-IN-1 (1 μM; 16 h) provides dose-dependent protection against TCZ (TNF-α, cycloheximide, z-VAD-fmk)-induced necroptosis in human HT-29 cells, and maintains normal cell morphology during necroptosis induction at a concentration of 1 μM[1].
RIPK1/RIPK3-PPI-IN-1 (16 h) exerts a dose-dependent protective effect against TZ (TNF-α and z-VAD-fmk)-induced necroptosis in mouse L929 cells[1].

Western Blot Analysis[1]

Cell Line: human HT-29 cells (TSZ-induced necroptosis model)
Concentration: 5-20 nM
Incubation Time: 6 h (TSZ stimulation)
Result: Completely suppressed phosphorylation of RIPK1, RIPK3, and MLKL at 20 nM after 6 hours of TSZ stimulation.
Allowed detectable phosphorylation of RIPK1, RIPK3, and MLKL at 5 and 10 nM.
Completely inhibited RIPK1 and RIPK3 phosphorylation within 6 h at 20 nM, subsequently blocking MLKL phosphorylation.
In Vivo

RIPK1/RIPK3-PPI-IN-1 (5-50 mg/kg; i.g.; single dose) dose-dependently alleviates TNF-α-induced SIRS in male C57BL/6J mice, conferring a 91.7% survival rate at the 50 mg/kg intragastric dose[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
