Nebivolol
Nebivolol is only found in individuals that have used or taken this drug. It is a highly cardioselective vasodilatory beta1 receptor blocker used in treatment of hypertension. In most countries, this medication is available only by prescription. [Wikipedia]Nebivolol is a selective β1-receptor antagonist. Activation of β1-receptors by epinephrine increases the heart rate and the blood pressure, and the heart consumes more oxygen. Nebivolol blocks these receptors which reverses the effects of epinephrine, lowering the heart rate and blood pressure. In addition, beta blockers prevent the release of renin, which is a hormone produced by the kidneys which leads to constriction of blood vessels. At high enough concentrations, this drug may also bind beta 2 receptors.

Gamma-CEHC
gamma-CEHC (gamma-carboxyethyl hydroxychroman) is a metabolite of vitamin E. Smokers have a significantly higher excretion level of urinary gamma-CEHC, and therefore require more vitamin E compared to non-smokers. Cigarette smoking is associated with increased oxidative stress and increased risk of degenerative disease. As the major lipophilic antioxidant, requirements for vitamin E may also be higher in smokers due to increased utilization (PMID: 15493460). gamma-CEHC is metabolites of Vitamin E.

5'-Carboxy-alpha-chromanol
5-carboxy-alpha-tocopherol is a dehydrogenation carboxylate product of 5-hydroxy-a-tocopherol by an unidentified microsomal enzyme(s) probably via an aldehyde intermediate. The tocopherols ( a-tocopherol , b-tocopherol ,r-tocopherol and d-tocopherol ) and their corresponding tocotrienols are synthesized by plants and have vitamin E antixoidant activity (see pathway vitamin E biosynthesis ). They differ in the number and location of methyl groups on the chromanol ring. The naturally occurring form of a-tocopherol is (2R,4R,8R)-a-tocopherol (synonym (R,R,R)-a-tocopherol). Synthetic a-tocopherols are a racemic mixture of eight different R and S stereoisomers. Only the 2R forms are recognized as meeting human requirements. The in vivo function of vitamin E is to scavenge peroxyl radicals via its phenolic (chromanol) hydroxyl group, thus protecting lipids against free radical-catalyzed peroxidation. The tocopheryl radical formed can then be reduced by reductants such as L-ascorbate. Other major products of a-tocopherol oxidation include α-tocopherylquinone and epoxy-a-tocopherols. The metabolites a-tocopheronic acid and its lactone, known as the Simon metabolites, are generally believed to be artefacts. In addition to these oxidation products, the other major class of tocopherol metabolites is the carboxyethyl-hydroxychromans.These metabolites are produced in significant amounts in response to excess vitamin E ingestion. Vitamin E is fat-soluble and its utilization requires intestinal fat absorption mechanisms. It is secreted from the intestine into the lymphatic system in chylomicrons which subsequently enter the plasma. Lipolysis of these chylomicrons can result in delivery of vitamin E to tissues, transfer to high-density lipoproteins (and subsequently to other lipoproteins via the phospholipid exchange protein), or retention in chylomicron remnants. These remnants are taken up by the liver. Natural (R,R,R)-α-tocopherol and synthetic 2R-α-tocopherols are then preferentially secreted from the liver into plasma as a result of the specificity of the α-tocopherol transfer protein. This protein, along with the metabolism of excess vitamin E in the liver and excretion into urine and bile, mediate the supply of a-tocopherol in plasma and tissues. 5-carboxy-alpha-tocopherol is a dehydrogenation carboxylate product of 5-hydroxy-a-tocopherol by an unidentified microsomal enzyme(s) probably via an aldehyde intermediate

From the metabolism end product, only that of r-tocopherol (2,7,8-trimethyl-2-(b-carboxyethyl)-6-hydroxychroman), but not that of a-tocopherol, was identified to provide natriuretic activity.

7'-Carboxy-alpha-tocotrienol
7-Carboxy-alpha-tocotrienol is a dehydrogenation carboxylate product of 7-hydroxy-a-tocotrienol by an unidentified microsomal enzyme(s) probably via an aldehyde intermediate. Tocotrienols are members of the vitamin E family. An essential nutrient for the body, vitamin E is made up of four tocopherols (alpha, beta, gamma, delta) and four tocotrienols (alpha, beta, gamma, delta).Chemically, vitamin E is an antioxidant. One model for the function of vitamin E in the body is that it protects cell membranes, active enzyme sites, and DNA from free radical damage. Tocotrienols are natural compounds found in select vegetable oils, wheat germ, barley, saw palmetto, and certain types of nuts and grains. This variant of vitamin E only occur at very low levels in nature. While the majority of research on vitamin E has focused on alpha-tocopherol, studies into tocotrienols account for less than 1\\% of all research into vitamin E. 7-Carboxy-alpha-tocotrienol is a dehydrogenation carboxylate product of 7-hydroxy-a-tocotrienol by an unidentified microsomal enzyme(s) probably via an aldehyde intermediate
