WY-14643 Usage And Synthesis

Description

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

Uses

A highly potent PPARα agonist

Uses

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

Definition

ChEBI: Pirinixic acid is a member of pyrimidines, an organochlorine compound and an aryl sulfide. It is functionally related to an acetic acid.

General Description

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.

Biological Activity

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 .

Biochem/physiol Actions

Selective PPARα agonist.

Safety Profile

Moderately toxic by ingestion. Suspected carcinogen with experimental carcinogenic and tumorigenic data. Mutation data reported. When heated to decomposition it emits very toxic fumes of Cl-, NOx and SOx

storage

Store at RT
