Background

Fenofibrate is a PPARα agonist with an EC50 of 30 μM.

Fenofibrate is a relatively potent inhibitor of CYP2B6 (IC50=0.7±0.2 μM) and CYP2C19 (IC50=0.2±0.1 μM). Fenofibrate is also a moderate inhibitor of CYP2C8 (IC50=4.8±1.7 μM) and CYP2C9 (IC50=9.7 μM)[1]. Fenofibrate binds to and inhibits cytochrome P450 epoxygenase (CYP)2C with higher affinity than to PPARα. Fenofibrate is a well-known PPARα agonist, but an in vitro assessment of 209 frequently prescribed drugs and related xenobiotics suggests that Fenofibrate is also a potent inhibitor of cytochrome P450 epoxygenase (CYP)2C. The affinity of Fenofibrate to CYP2C is >10 times higher (EC50=2.39±0.4 μM) than to PPARα (EC50=30 μM). Fenofibrate at a low dose inhibits CYP2C8 activity without PPARα activation[2].

Daily intake of Fenofibrate at this low dose (10 μg/g/day) inhibits retinal and choroidal neovascularization induced by CYP2C8 overexpression by 29% (P=0.021) and 36% (P=1.2×10?9) respectively[2].

Protocol

Cell experiment [1]:
Cell lines	MCF-7 and Panc-1 cells
Preparation method	The solubility of this compound in DMSO is > 12.8 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 °C for several months.
Reacting condition	24, 48 and 72 hrs
Applications	At 24th, 48th and 72th hrs, the IC50 values of Fenofibrate were 96.6, 46.5 and 9.2 μg/mL on Panc-1 cells, and 93.5, 55.9 and 8 μg/mL on MCF-7 cells, respectively. Compared with the untreated solvent control, MCF-7 and Panc-1 cells treated with 1/2 IC50, IC50 and 2 IC50 of Fenofibrate for 24 hrs exhibited a significant increase in the relative activity of caspase 3/7.
Animal experiment [1]:
Animal models	Mice bearing Ehrlich ascites carcinoma (EAC)
Dosage form	200 mg/kg/day; p.o.; for 18 days
Applications	In an EAC mouse model, Fenofibrate significantly reduced tumor weight and volume, without affecting the relative heart weight. However, Fenofibrate treatment significantly decreased the body weight and increased the relative liver weight. In addition, a marked decrease in the carcinoembryonic antigen (CEA) level was also observed in the Fenofibrate treatment group.
Other notes	Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
