RIPK3 Inhibitor

RIPK1-IN-39 (compound 2) is a potent and selective RIPK1 inhibitor (IC₅₀ = 69.40 nM) exhibiting >100-fold selectivity over RIPK3 (IC₅₀ = 6946 nM). RIPK1-IN-39 protects HT-22 and HT-29 cells from necroptosis by inhibiting the phosphorylation and activation of the RIPK1-RIPK3-MLKL pathway. RIPK1-IN-39 demonstrates neuroprotective effects in a rat model of middle cerebral artery occlusion (MCAO). RIPK1-IN-39 can be used for acute ischemic stroke (AIS) research.

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.

Ligustroflavone (Standard) is the analytical standard of Ligustroflavone (HY-N0546). This product is intended for research and analytical applications. Ligustroflavone is an orally active flavonoid compound. Ligustroflavone can be extracted from Ligustrum lucidum. Ligustroflavone antagonizes the calcium-sensing receptor (CaSR), inhibits the RIPK1/RIPK3/MLKL pathway, and downregulates TGF-β/Smad signaling. Ligustroflavone regulates calcium metabolism, protects bone tissue, reduces cerebral ischemic injury, and inhibits liver fibrosis. Ligustroflavone can be used in the study of diabetic osteoporosis, ischemic stroke, and liver fibrosis.
