In Vitro

WY-14643 is an agonist of PPARα, with EC50s of 0.63 μM, 32 μM for murine PPARα and PPARγ, and 5.0 μM, 60 μM, 35 μM for human PPARα, PPARγ and PPARδ, respectively.

WY-14643 (Wy-14643; 0, 10, 100 μM) enhances protein expression of PPAR-α in synovial fibroblasts.

WY-14643 (0, 10, 100 μM) shows inhibitroy effects on NO and PGE2 production in LPS-stimulated synovial fibroblasts.

WY-14643 also effectively downregulates expression of inflammatory mediators such as VCAM-1, ICAM-1, ET-1, and TF in synovial fibroblasts, blocks LPS-induced NF-kB activation, IkB phosphorylation, and NF-kB nuclear translocation in synovial fibroblasts, but Pirinixic acid shows no effects in PPAR-α silenced cells.


In Vivo

WY-14643 (Wy-14643; 10 mg/kg, i.v.) decreases hepatic injury and lipid peroxidation (MDA) levels in obese rats. WY-14643 also causes increased SIRT1 activity in Sham and ischemia-reperfusion (IR) group, but shows no effects on SIRT3 protein expression. WY-14643 enhances NAD+, and ATP levels, and prevents endoplasmic reticulum stress (ERS) in rats.
