WY-14643 (50892-23-4) is a selective PPARα agonist (EC50=0.63, 32 and >100 μM for PPARα,γ and δ, respectively).1? Displays anti-inflammatory activity2 and reduces LPS-induced inflammation in alveolar epithelial cells3. Induces “browning” of white adipocytes in combined treatment with retinoic acid.4? Stimulates ADAM10-mediated proteolysis of? amyloid precursor protein in a mouse model.5 Down regulates NFkB transcriptional activity. Review.6
A highly potent PPARα agonist
WY-14643 has been used:
- as a positive control for transfection and luciferase assay
- to stimulate bone marrow–derived macrophages (BMDM) for autophagic flux analysis
- to analyze the regulation of fatty acid metabolism-immune nexus (FAMIN) expression in cell culture
ChEBI: Pirinixic acid is a member of pyrimidines, an organochlorine compound and an aryl sulfide. It is functionally related to an acetic acid.
WY-14643 prevents lipopolysaccharide (LPS)-induced inflammation in synovial fibroblasts. It protects cortical neurons from pro-inflammatory mediator-induced cell injuries. WY-14643 has inhibitory effects on pro-inflammatory responses in microglia. It improves oxido-nitrosative stress in disease models and reduces the generation of reactive oxygen species (ROS), nitric oxide (NO) and lipid peroxidation end-products in the brain.
Selective PPAR α agonist (EC 50 values are 0.63, 32 and > 100 μ M at PPAR α , PPAR γ and PPAR δ respectively). Negatively inhibits NF- κ B transcriptional activity and decreases the inflammatory response in vitro and in vivo .
Moderately toxic by
ingestion. Suspected carcinogen with
experimental carcinogenic and tumorigenic
data. Mutation data reported. When heated
to decomposition it emits very toxic fumes
