Description
Choline fenofibrate, a salt formulation of fenofibric acid, is a lipid
regulating agent available as delayed release capsules for oral administration. It is indicated in combination with a statin to reduce TG and
increase high-density lipoprotein cholesterol (HDL-C) in patients with
mixed dyslipidemia and coronary heart disease (CHD) or a CHD-risk
equivalent who are optimal for statin therapy to achieve their lowdensity lipoprotein cholesterol (LDL-C) goal. In addition, choline
fenofibrate is indicated as monotherapy in patients with severe
hypertriglyceridemia to reduce TG, and in patients with primary
hyperlipidemia or mixed dyslipidemia to reduce elevated LDL-C, total
cholesterol, TG, apolipoprotein B, and to increase HDL-C. Fenofibric acid
is also the active metabolite of fenofibrate (Tricor), which has been
previously marketed for the treatment of hypercholesterolemia and
hypertriglyceridemia.
The primary mode of action of fenofibric acid
is through the activation of the nuclear transcription factor PPARa,
predominantly expressed in tissues that metabolize fatty acids, such as
the liver, kidney, heart, and muscle.On activation by binding of the fibrate, PPARa binds as heterodimers with retinoid X receptor (RXR), which subsequently recognizes and binds to specific PPARa-response elements leading to modulation of expression of the target genes. In particular, the activity of lipoprotein lipase is increased and synthesis of apoprotein C-III is decreased, which together enhance the clearance of circulating TG-rich lipoproteins. The resulting fall in TG produces an alteration in the size and composition of LDL from small dense particles to large buoyant particles. These larger particles have a greater affinity for cholesterol receptors and are catabolized rapidly. Choline fenofibriate acid is contraindicated in patients with severe renal impairment.

Synthesis
Choline To Market, To Market 2008 enofibrate is chemically derived from p-anisole in four steps through Friedel Crafts acylation with p-chlorobenzoyl chloride to the corresponding benzophenone derivative, followed by methyl ether cleavage with hydrogen bromide, alkylation of the phenolic hydroxyl group with 2-bromo-2-methylpropanoic acid using sodium hydroxide, and finally salt formation with choline.
Check Digit Verification of cas no
The CAS Registry Mumber 856676-23-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,6,6,7 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 856676-23:
(8*8)+(7*5)+(6*6)+(5*6)+(4*7)+(3*6)+(2*2)+(1*3)=218
218 % 10 = 8
So 856676-23-8 is a valid CAS Registry Number.

Interesting morphological behavior of organic salt choline fenofibrate: Effect of supersaturation and polymeric impurity

Crystal habit of drug molecules can have significant influence on the processing and performance of pharmaceutical products. During the development of Trilipix, a pharmaceutical product used for the treatment of mixed dyslipidemia, several crystal habits were observed for the active ingredient choline fenofibrate. The dissolution and performance of the drug product were not impacted by changes in crystal habit of the active ingredient due to high solubility of the drug. However, the formulation process was impacted by variations in crystal habit of the active ingredient, requiring robust control of the crystal habit. The crystal habit was greatly influenced by supersaturation during crystallization from a mixed solvent system comprising methanol and isopropanol. In addition to supersaturation, trace levels of a polymeric impurity in the starting material fenofibrate had a detrimental effect on the crystal habit. This article discusses the effects of these factors on the crystal habit of choline fenofibrate and the design of a crystallization process to deliver the target crystal habit, most suited to the formulation process. The article also provides preliminary mechanistic insights into the crystal habit of this organic salt using an extension of the spiral growth model for morphology prediction of organic molecular crystals. An attempt is made to explain the effect of supersaturation and impurity on the crystal habit of choline fenofibrate using the concepts of stability of surfaces, building units, periodic bond chain theory, and the spiral growth model.
