Description
Fenofibrate, also known as Tricor, is a chlorobenzophenone derivative with structural features similar to clofibrate, but with a more potent hypocholesterolemic and triglyceride-lowering effect due to its greater lipophilic character. It is a crystalline solid and is used in the treatment of various conditions related to cardiovascular diseases and lipid metabolism.
Uses
Used in Cardiovascular Disease Treatment:
Fenofibrate is used as a lipid-lowering agent for the management of cardiovascular diseases. It helps in reducing the levels of low-density lipoprotein (LDL) cholesterol and triglycerides while increasing the levels of high-density lipoprotein (HDL) cholesterol, thus improving the overall lipid profile and reducing the risk of cardiovascular events.
Used in Research Studies:
Fenofibrate is used as a research tool to study its effect on plasma lipids, liver phenotype, and gene expression. This helps in understanding the underlying mechanisms of its action and its potential role in the treatment of various metabolic disorders.
Used in Endothelium-Dependent Vasodilation Studies:
Fenofibrate is used as a pharmacological agent to study its impact on endothelium-dependent vasodilatation of the thoracic aorta. This helps in understanding the role of fenofibrate in improving vascular function and its potential benefits in the treatment of cardiovascular diseases.
Used in Non-Alcoholic Steatohepatitis (NASH) Research:
Fenofibrate is used as a treatment agent in NASH knock-in mice along with a high-fat diet (HFD) to study its effect on the development and progression of the disease. This helps in evaluating the potential therapeutic role of fenofibrate in the management of NASH and related metabolic disorders.

Manufacturing Process
(a) Preparation of p-(4-chlorobenzoyl)-phenoxyisobutyric acid: 1 mol of 4-
hydroxy-4'-chlorobenzophenone is dissolved in anhydrous acetone and then 5
mols of powdered sodium hydroxide is added. The corresponding sodium
phenoxide precipitates. Refluxing is effected, and then, 1.5 mols of CHCl3
diluted with anhydrous acetone is added and the resulting mixture is refluxed
for 10 hours. After cooling, water is added, the acetone is evaporated, the
aqueous phase is washed with ether and acidified and the organic phase is
redissolved in ether and extracted into a solution of bicarbonate. The
bicarbonate solution is than acidified to obtain the desired acid, having a
melting point of 185°C, with a yield of 75%.(b) Preparation of fenofibrate: 1 mol of the acid obtained is converted into its
acid chloride using thionyl chloride (2.5 mols). 1 mol of the acid chloride is
then condensed with 1.05 mol of isopropyl alcohol in the presence of 0.98 mol
of pyridine in an inert solvent such as benzene.Since traces of SO2 (which has a bad smell) may be obtained from the thionyl
chloride, it is preferable to avoid this disadvantage by carrying out the
esterification directly.
Biochem/physiol Actions
Fenofibrate increases high density lipoprotein levels by reducing cholesteryl ester transfer protein expression. It is used in treating the condition of increased cholesterol levels in the blood, abnormal lipid levels in the body and also hypertriglyceridaemia. Fenofibrate is a lipid regulating drug and proliferator-activated receptor-α (PPARα) mediates its action. It decreases the plasma levels of fibrinogen and C-reactive protein. By this fenofibrate allows better flow-mediated dilatation and reduces the risk of atherosclerosis. Fenofibrate is also known to reduce uric acid levels.

Drug interactions
Potentially hazardous interactions with other drugs
Antibacterials: increased risk of myopathy with
daptomycin - try to avoid concomitant use.
Anticoagulants: enhances effect of coumarins and
phenindione; dose of anticoagulant should be
reduced by up to 50% and readjusted by monitoring
INR.
Antidiabetics: may improve glucose tolerance
and have an additive effect with insulin or
sulphonylureas.
Ciclosporin: ciclosporin levels appear to be
unaffected; however, it is recommended that
concomitant therapy should be avoided because of
the possibility of elevated serum creatinine levels.
Colchicine: possible increased risk of myopathy.
Lipid-regulating drugs: increased risk of myopathy
in combination with statins and ezetimibe
(maximum 20 mg of rosuvastatin); increased risk of
cholelithiasis and gallbladder disease with ezetimibe
- avoid with ezetimibe.
Metabolism
After oral administration, fenofibrate is rapidly
hydrolysed by esterases to the active metabolite fenofibric
acid.No unchanged fenofibrate can be detected in the plasma.
Fenofibric acid is excreted mainly in the urine, mainly as
the glucuronide conjugate, but also as a reduced form of
fenofibric acid and its glucuronide; practically all the drug
is eliminated from the body within 6 days
Check Digit Verification of cas no
The CAS Registry Mumber 49562-28-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,5,6 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 49562-28:
(7*4)+(6*9)+(5*5)+(4*6)+(3*2)+(2*2)+(1*8)=149
149 % 10 = 9
So 49562-28-9 is a valid CAS Registry Number.

The carbonyl compounds, synthesized by the oxidative cleavage of their corresponding olefins, are of great significance in organic synthesis, especially aryl ketones. We have developed a gentle and effective protocol, using acid red 94 as the organic metal-free photocatalyst, O2 as the oxidant, and water as the solvent. Under visible light irradiation, aryl ketone derivatives were obtained in moderate to excellent yields, showing good economic and environmental advantages.

Synthesis and evaluation of fenofibric acid ester derivatives: Studies of different formulation with their bioavailability and absorption conditions
Lv, Zhixiang,Wang, Zhou,Xiao, Fuyan,Jin, Guofan
, p. 280 - 287 (2020/01/03)
A series of fenofibric acid ester pro-drugs (JF-1-7) were synthesized. The pharmacokinetic properties of these pro-drugs were examined after oral administration to rats at a dose of 20 mg kg-1 to evaluate the relative bioavailability in rats. The bioavailability of the ester compounds, JF-1, 2, 3, 4, 5, 6, and 7, was significantly higher than that of fenofibrate. In particular, JF-2 proved to be most promising. The oral administration (20 mg kg-1) of JF-2 showed a relative bioavailability of approximately 272.8percent compared to fenofibrate.
