Fenofibric acid (FNF acid) is the active form of fenofibrate, a synthetic phenoxy-isobutyric acid derivate with antihyperlipidemic activity.

PPARδ:1.06 µM(EC50), PPARγ:1.47 µM(EC50), COX-2:48 nM, PPARα:22.4 µM(EC50)

PPAR activators fenofibric acid is dissolved in DMSO and added to the culture medium containing 0.2% BSA. RAW264 cells are washed with PBS and cultured an additional 48 hours in the presence of fenofibric acid in DMEM/F-12(1:1) medium containing 2% TCM and 0.2% BSA. During the last 24 hours of the drug treatment, 300 mol/L of dibutyryl cAMP and apoA-I (10 μg/mL) are added to the medium. THP-1 cells are also treated with the compound and apoA-I in 0.2% BSA-RPMI 1640 medium and 0.1% BSA-MEM. Cholesterol and choline-phospholipid released into the medium by apoA-I are determined enzymatically. Adherent cells are dissolved in 0.1 N NaOH for protein determination by bicinchoninic acid protein assay system. (Only for Reference)
