WJH-C19
Based on 1 Customer Validation
WJH-C19 is an orally active RIPK1 inhibitor with an IC50 of 5.7 nM. WJH-C19 inhibits the RIPK1/RIPK3/MLKL signaling axis, blocks RIPK1 phosphorylation, suppresses the phosphorylation of downstream RIPK3 and MLKL, disrupts necrosome formation, and exhibits protective effects against necroptosis (Apoptosis) in multiple cell lines. WJH-C19 ameliorates symptoms of inflammatory bowel disease in a mouse colitis model by regulating the necroptosis pathway. WJH-C19 alleviates inflammation and bone destruction in a mouse model of rheumatoid arthritis. WJH-C19 is applicable to research related to inflammatory bowel disease and rheumatoid arthritis.

Biological Activity
|
RIPK1 5.7 nM (IC50) |
RIPK3 |
WJH-C19 (Compound 10e12) (25 h) exerts potent, concentration-dependent protective effects against necroptosis in multiple cell lines, with EC50 values of 0.28 nM in L929 cells, 4.0 nM in HT22 cells, 1.6 nM in HT29 cells, and 2.0 nM in U937 cells; in addition, this compound reduces necroptotic L929 cells in a dose-dependent manner[1].
WJH-C19 potently inhibits the kinase activity of RIPK1, with an IC50 value of 5.7 nM[1].
WJH-C19 (0.5-50 nM) concentration-dependently inhibits the TNFα/z-VAD-FMK (HY-16658BG) (TZ)-induced phosphorylation of RIPK1, RIPK3 and MLKL in L929 cells, as well as the mTNFα/Smac mimetic/z-VAD-FMK (TSZ)-induced phosphorylation in HT29 cells, thereby blocking necrosome formation and the downstream necroptotic signaling pathway[1].

WJH-C19 (10-20 mg/kg; p.o.; daily; 14 days) potently ameliorates complete Freund's adjuvant (CFA, HY-153808)-induced rheumatoid arthritis in female C57BL/6 mice, reduces paw swelling, joint inflammation and bone destruction, and inhibits the RIPK1/RIPK3/MLKL signaling axis[1].

Animal Model:C57BL/6 (female, 10-12 weeks old, ~28 g, DSS-induced colitis)[1]
-
Dosage:2.5 mg/kg; 1.25 mg/kg
-
Administration:p.o.; daily; 7 days
-
Result:Achieved 47.5% body weight recovery, 42.9% disease activity index (DAI) reduction, and 60.5% colon length recovery at 2.5 mg/kg.
Achieved 33.2% body weight recovery, 32.1% DAI reduction, and 35.1% colon length recovery at 1.25 mg/kg.
Reduced proinflammatory cytokine levels (IL-1β, IL-6, TNFα) and increased anti-inflammatory cytokine IL-10 levels in colon tissue at both doses.
Inhibited phosphorylation of RIPK1, RIPK3, and MLKL in colonic proteins at both doses, with the high dose showing the most robust inhibition.
Reduced mucosal damage, maintained intact glandular architecture, and restored zonula occludens-1 (ZO-1) and Occludin expression at both doses, with the high-dose group exhibiting near-normal morphology.
-
Animal Model:C57BL/6 (female, 8 weeks old, CFA-induced rheumatoid arthritis)[1]
-
Dosage:20 mg/kg; 10 mg/kg
-
Administration:p.o.; daily; 14 days
-
Result:Reduced paw swelling percentage, ankle joint temperature, and arthritis index scores in a dose-dependent manner at both doses, with efficacy comparable or superior to celecoxib.
Reduced osteophyte formation and reversed bone destructive changes, including improvements in bone mineral density (BMD), cortical BMD, trabecular number (Tb.N), connectivity density (Conn.D), bone volume (BV), cortical volume (CV), trabecular separation (Tb.Sp), pore number (Po.N), cortical area (Ct.Ar), and cortical thickness (Ct.Th) at both doses, with the high dose showing the most pronounced improvement.
Reduced inflammatory cell infiltration, synovial hyperplasia, and cartilage erosion at both doses, with the high-dose group achieving histological scores approaching normal levels.
Reduced the M1/M2 macrophage ratio in spleens in a dose-dependent manner at both doses, shifting toward the anti-inflammatory M2 phenotype.
Suppressed expression of phosphorylated RIPK1, RIPK3, and MLKL in ankle joints at both doses, with the high dose showing the strongest inhibition.
