cholesterol esters

Pitavastatin calcium (NK-104) is a potent inhibitor of HMG-CoA reductase (Ki: 1.7 nM). It lowers both total cholesterol and low-density lipoprotein cholesterol in animals and humans. Metabolism of pitavastatin by the cytochrome P450 system is minimal, reducing the risk of drug-drug interactions.

Cholesteryl behenate is a standard in electrospray ionization tandem mass spectrometry for the analysis of cholesteryl esters and cholesterol.

YM-750 is a potent inhibitor of acyl-CoA:cholesterol acyltransferase (ACAT), with an IC50 value of 0.18 μM. ACAT is an enzyme that catalyzes the conversion of cholesterol and long-chain fatty-acyl-coenzyme A into cholesteryl esters.

Acyl-coenzyme A: cholesterol acyltransferase-1 and -2 (ACAT-1 and ACAT-2) catalyze the formation of cholesterol esters from cholesterol and long chain fatty acyl-coenzyme A, and may play a role in the development of atherosclerosis. CAY10485 inhibits human ACAT-1 and ACAT-2 with an IC50 values of 95 and 81 μM, respectively. It also inhibits copper-mediated oxidation of low density lipoproteins by 91% at a concentration of 2 μM.

Acyl-Coenzyme A: cholesterol acyltransferase-1 and -2 (ACAT-1 and ACAT-2) catalyze the formation of cholesterol esters from cholesterol and long chain fatty acyl-coenzyme A, and may play a role in the development of atherosclerosis. CAY10486 inhibits human ACAT-1 and ACAT-2 equally with an IC50 value of approximately 60 μM. It also inhibits copper-mediated oxidation of low density lipoproteins by about 28% at a concentration of 3 μM.

Cholesteryl heptadecanoate is a cholesterol ester (CE) formed by the condensation of cholesterol with heptadecanoic acid, a C-17 saturated fatty acid that does not occur in any natural animal or vegetable fat at high concentrations. As such, it is commonly used as an internal standard for the quantification of cholesterol esters by GC- or LC-mass spectrometry. CEs are major constituents of lipoprotein particles carried in blood and accumulate in the fatty acid lesions of atherosclerotic plaques. CEs of various fatty acids are major constituents of murine and human adrenal glands.

Cholesteryl erucate, a cholesterol ester, serves as a standard for the quantification of cholesterol esters in human meibomian gland secretions.

Cholesteryl palmitic acid is a cholesteryl ester. A cholesteryl ester is an ester of cholesterol. Fatty acid esters of cholesterol constitute about two-thirds of the cholesterol in the plasma. Cholesterol is a sterol (a combination of steroid and alcohol) and a lipid found in the cell membranes of all body tissues and transported in the blood plasma of all animals. The accumulation of cholesterol esters in the arterial intima (the innermost layer of an artery, in direct contact with the flowing blood) is a characteristic feature of atherosclerosis. Atherosclerosis is a disease affecting arterial blood vessels. It is a chronic inflammatory response in the walls of arteries, in large part to the deposition of lipoproteins (plasma proteins that carry cholesterol and triglycerides).

Pentacosanoic acid, belongs to the class of organic compounds known as very long-chain fatty acids.

Cholesteryl palmitoleate, a cholesterol ester, exhibits elevated plasma levels in ApoE- - mice following exposure to cigarette smoke and in pediatric patients diagnosed with biliary atresia. It serves as a standard for identifying cholesterol esters in human meibomian gland secretions.

Cholesteryl 11,14-eicosadienoate, a cholesterol ester, serves as a synthetic intermediate in the production of cholesterol (methyl) esters.

Helminthosporol is a natural plant growth regulator that promotes the growth of rice and lettuce seedlings. It also inhibits the activity of acyl-CoA:cholesterol acyltransferase (ACAT) in rat liver microsomes and the synthesis of cholesterol esters in macrophages.

Cholesteryl n-butyrate is a cholesterol ester formed from two naturally occurring substances: cholesterol and butyric acid. It can be utilized in synthesizing solid lipid nanoparticles (SLN) that inhibit the adhesion and migration of colon cancer cells, thus serving as a delivery system for the anticancer agent butyrate esters.

Cholesterolhexanoate is an organic compound classified under esters. It is formed through the reaction between cholesterol and hexanoic acid. Cholesterolhexanoate has various applications in the pharmaceutical industry, particularly as a bioactive compound with potential research roles for improving conditions such as high cholesterol and inflammation-related diseases. Additionally, it may serve as a food additive to enhance texture and stability.
