WY 14643 is a highly potent PPARalpha agonist. Peroxisome proliferator-activated receptors (PPARs) alpha, beta, and gamma are hormone receptors that induce the gene acyl-Coa and modulate the peroxisomal beta oxidation of fatty acids. WY 14643 may act to inhibit TNF-alpha-induced VCAM-1, and reduce TNF-alpha and IL-1beta. Studies indicate that WY 14643 inhibits proliferation of trophoblast cells at lower concentrations than clofibric acid (sc-203000), and decreases the levels of S-100 β chain (S100B) protein.

Rated 5 out of 5 by from BurokerBuroker, N.E. et al. (PubMed 16985257) used WY 14643, a potent PPAR agonist, to determine if there were any interactions between PPAR and thyroid hormone receptors in the heart. Introduction of WY 14643 induced a twofold increase in gene expression of the reporter UCP3, indicating a novel interaction between PPAR and thyroid hormone receptors. -SCBT Publication Review
