Carnosol is a naturally occurring phenolic diterpene found in rosemary (Rosemarinus officinalis, Labiatae). It has been known that an extract of rosemary leaves contains high antioxidative activity. Ninety percent of this antioxidative activity can be attributed to carnosol and carnosic acid. Carnosic acid is easily converted to carnosol by oxidation. Carnosol has multiple beneficial medicinal effects including anti-inflammatory, anti-microbial and anti-cancer activities in various disease models. Carnosol may possess important neuroprotective effects against rotenone-induced DA neuronal damage. Naturally occurring antioxidants reduce the risk of neurodegenerative diseases. In addition, carnosol and carnosic acid promoted the synthesis of nerve growth factor in glial cells. Carnosol-mediated neuroprotection in DA neurons is involved in the attenuation of caspase-3 activity, which was induced by rotenone. Furthermore, carnosol-mediated tyrosine hydroxylase (TH) increase, which is dependent on the Raf-mitogen-activated protein kinase (MEK)-extracellular signal-regulated kinase (ERK)1/2 signaling pathway, is responsible for the neuroprotection in SN4741 DA cells. (PMID: 17047462). Carnosol, a phenolic diterpene compound of the labiate herbs rosemary and sage, is an activator of the human peroxisome proliferator-activated receptor gamma (PPARgamma), a ligand activated transcription factor, belonging to the metazoan family of nuclear hormone receptors. Activation of PPARgamma increases the transcription of enzymes involved in primary metabolism, leading to lower blood levels of fatty acids and glucose. Hence, PPARgamma represents the major target for the glitazone type of drugs currently being used clinically for the treatment of type 2 diabetes. (PMID: 16858665). Bitter principle in Salvia carnosa, Salvia officinalis (sage), Salvia triloba (Greek sage) and Rosmarinus officinalis (rosemary). Nutriceutical with anticancer props. Carnosol is a diterpenoid. Carnosol is a natural product found in Podocarpus rumphii, Lepechinia salviae, and other organisms with data available.

Se-Methylselenocysteine

selenomethylselenocysteine, (L)-isomer, 75Se-labeled

C4H9NO2Se (182.9798)


Se-Methylselenocysteine (SeMSC) is a naturally occurring seleno-amino acid that is synthesized by plants such as garlic, astragalus, onions, and broccoli. It cannot be synthesized by higher animals. Unlike selenomethionine, which is incorporated into proteins in place of methionine, SeMSC is not incorporated into any proteins, thereby being fully available for the synthesis of selenium-containing enzymes such as glutathione peroxidase. Selenomethionine is the major seleno-compound in cereal grains (wheat grain, maize, and rice), soybeans, and enriched yeast. Seleno-compounds present in plants may have a profound effect upon the health of animals and human subjects. It is now known that the total Se content cannot be used as an indication of its efficacy, but knowledge of individual selenocompounds is necessary to fully assess the significance. Thus, speciation of the seleno-compounds has moved to the forefront. Since animals and man are dependent upon plants for their nutritional requirements, this makes the types of seleno-compounds in plants even more critical. Se enters the food chain through incorporation into plant proteins, mostly as selenocysteine and selenomethionine at normal Se levels. There are two possible pathways for the catabolism of selenomethionine: (1) a transsulfuration pathway via selenocystathionine to produce selenocysteine, which in turn is degraded to H2Se by the enzyme beta-lyase and (2) a transamination-decarboxylation pathway. It was estimated that 90\\\\% of methionine is metabolized through this pathway and thus could be also the major route for selenomethionine catabolism (PMID: 14748935 , Br J Nutr. 2004 Jan;91(1):11-28.). Selenomethionine is an amino acid containing selenium. The L-isomer of selenomethionine, known as Se-met and Sem, is a common natural food source of selenium. In vivo, selenomethionine is randomly incorporated instead of methionine and is readily oxidized. Its antioxidant activity arises from its ability to deplete reactive species. Selenium and sulfur are chalcogen elements that share many chemical properties and the substitution of methionine to selenomethionine may have no effect on protein structure and function. However, the incorporation of selenomethionine into tissue proteins and keratin in horses causes alkali disease. Alkali disease is characterized by emaciation, loss of hair, deformation and shedding of hooves, loss of vitality, and erosion of the joints of long bones. Se-methyl-L-selenocysteine is an L-alpha-amino acid compound having methylselanylmethyl as the side-chain. It has a role as an antineoplastic agent. It is a Se-methylselenocysteine, a non-proteinogenic L-alpha-amino acid and a L-selenocysteine derivative. It is a conjugate base of a Se-methyl-L-selenocysteinium. It is a conjugate acid of a Se-methyl-L-selenocysteinate. It is an enantiomer of a Se-methyl-D-selenocysteine. It is a tautomer of a Se-methyl-L-selenocysteine zwitterion. Methylselenocysteine has been used in trials studying the prevention of Prostate Carcinoma and No Evidence of Disease. Se-Methylselenocysteine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Methylselenocysteine is a naturally occurring organoselenium compound found in many plants, including garlic, onions, and broccoli, with potential antioxidant and chemopreventive activities. Se-Methyl-seleno-L-cysteine (MSC) is an amino acid analogue of cysteine in which a methylselenium moiety replaces the sulphur atom of cysteine. This agent acts as an antioxidant when incorporated into glutathione peroxidase and has been shown to exhibit potent chemopreventive activity in animal models. Se-Methylselenocysteine (SeMSC) is a naturally occurring seleno-amino acid that is synthesized by plants such as garlic, astragalus, onions and broccoli. Unlike selenomethionine, which is incorporated into proteins in place of methionine, SeMSC is not incorporated into any proteins, thereby being fully available for the synthesis of selenium-containing enzymes such as glutathione peroxidase. 3-(Methylseleno)alanine is found in many foods, some of which are common cabbage, white cabbage, lima bean, and cauliflower.

Selenomethionine

Selenomethionine, United States Pharmacopeia (USP) Reference Standard

C5H11NO2Se (196.9955)


L-selenomethionine is the L-enantiomer of selenomethionine. It is an enantiomer of a D-selenomethionine. It is a tautomer of a L-selenomethionine zwitterion. Selenomethionine is a naturally occuring amino acid in some plant materials such as cereal grains, soybeans and enriched yeast but it cannot be synthesized from animals or humans. It can be produced from post-structural modifications. *In vivo*, selenomethionine plays an essential role in acting as an antioxidant, where it depletes reactive oxygen species (ROS) and aids in the formation and recycling of glutathione, another important antioxidant. In comparison to selenite, which is the inorganic form of selenium, the organic form of selenomethionine is more readily absorbed in the human body. Selenomethionin is used in biochemical laboratories where its incorporation into proteins that need to be visualized enhances the performance of X-ray crystallography. L-Selenomethionine is the amino acid methionine with selenium substituting for the sulphur moiety. Methionine is an essential amino acid in humans, whereas selenium is a free-radical scavenging anti-oxidant, essential for the protection of various tissues from the damages of lipid peroxidation. As a trace mineral that is toxic in high doses, selenium is a cofactor for glutathione peroxidase, an anti-oxidant enzyme that neutralizes hydrogen peroxide. L-Selenomethionine is considered a safe, efficacious form of selenium and is readily bioavailable. Selenium may be chemoprotective for certain cancers, particularly prostate cancer. (NCI04) Diagnostic aid in pancreas function determination. Selenomethionine (CAS: 1464-42-2) is an amino acid containing selenium that cannot be synthesized by higher animals but can be obtained from plant material.

Prostaglandin B1

7-{2-[(1E,3S)-3-hydroxyoct-1-en-1-yl]-5-oxocyclopent-1-en-1-yl}heptanoic acid

C20H32O4 (336.23)


Prostaglandin B1 (PGB1) is a metabolite of PGE1. PGE1 is a prostanoid. Prostanoids is a term that collectively describes prostaglandins, prostacyclines and thromboxanes. Prostanoids are a subclass of the lipid mediator group known as eicosanoids. They derive from C-20 polyunsaturated fatty acids, mainly dihomo-gamma-linoleic (20:3n-6), arachidonic (20:4n-6), and eicosapentaenoic (20:5n-3) acids, through the action of cyclooxygenases-1 and -2 (COX-1 and COX-2). PGB1does not inhibit phospholipase activity, but oligomers of PGB1 (PGBx) extracted from human neutrophils inhibit human phospholipases A2 in vitro and in situ in a dose-dependent manner; these oligomers inhibit arachidonic acid mobilization in human neutrophils and endothelial cells. One mechanism for the pharmacological effects of PGBx may be inhibition of cell-associated and extracellular phospholipase A2. PGB1 has the ability to enhance peripheral vascular resistance and elevate blood pressure. The effect is not central in origin and apparently is not the result of changes in cholinergic or alpha-adrenoceptor sensitivity or changes in vascular smooth muscle susceptibility per se. PGB1 blocks S-phase DNA synthesis; inhibition of DNA synthesis does not appear to require elevated levels of cAMP. (PMID: 7667505, 1477202, 2129000, 2597672, 6635328). Prostaglandins are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signalling pathways. Prostaglandin B1 (PGB1) is a metabolite of PGE1. PGE1 is a prostanoid.

Glutathione

(2S)-2-amino-4-{[(1R)-1-[(carboxymethyl)carbamoyl]-2-sulfanylethyl]carbamoyl}butanoic acid

C10H17N3O6S (307.0838)


Glutathione is a compound synthesized from cysteine, perhaps the most important member of the bodys toxic waste disposal team. Like cysteine, glutathione contains the crucial thiol (-SH) group that makes it an effective antioxidant. There are virtually no living organisms on this planet-animal or plant whose cells dont contain some glutathione. Scientists have speculated that glutathione was essential to the very development of life on earth. glutathione has many roles; in none does it act alone. It is a coenzyme in various enzymatic reactions. The most important of these are redox reactions, in which the thiol grouping on the cysteine portion of cell membranes protects against peroxidation; and conjugation reactions, in which glutathione (especially in the liver) binds with toxic chemicals in order to detoxify them. glutathione is also important in red and white blood cell formation and throughout the immune system. glutathiones clinical uses include the prevention of oxygen toxicity in hyperbaric oxygen therapy, treatment of lead and other heavy metal poisoning, lowering of the toxicity of chemotherapy and radiation in cancer treatments, and reversal of cataracts. (http://www.dcnutrition.com/AminoAcids/) glutathione participates in leukotriene synthesis and is a cofactor for the enzyme glutathione peroxidase. It is also important as a hydrophilic molecule that is added to lipophilic toxins and waste in the liver during biotransformation before they can become part of the bile. glutathione is also needed for the detoxification of methylglyoxal, a toxin produced as a by-product of metabolism. This detoxification reaction is carried out by the glyoxalase system. Glyoxalase I (EC 4.4.1.5) catalyzes the conversion of methylglyoxal and reduced glutathione to S-D-Lactoyl-glutathione. Glyoxalase II (EC 3.1.2.6) catalyzes the hydrolysis of S-D-Lactoyl-glutathione to glutathione and D-lactate. GSH is known as a substrate in both conjugation reactions and reduction reactions, catalyzed by glutathione S-transferase enzymes in cytosol, microsomes, and mitochondria. However, it is also capable of participating in non-enzymatic conjugation with some chemicals, as in the case of n-acetyl-p-benzoquinone imine (NAPQI), the reactive cytochrome P450-reactive metabolite formed by acetaminophen, that becomes toxic when GSH is depleted by an overdose (of acetaminophen). glutathione in this capacity binds to NAPQI as a suicide substrate and in the process detoxifies it, taking the place of cellular protein thiol groups which would otherwise be covalently modified; when all GSH has been spent, NAPQI begins to react with the cellular proteins, killing the cells in the process. The preferred treatment for an overdose of this painkiller is the administration (usually in atomized form) of N-acetylcysteine, which is used by cells to replace spent GSSG and renew the usable GSH pool. (http://en.wikipedia.org/wiki/glutathione). Glutathione (GSH) - reduced glutathione - is a tripeptide with a gamma peptide linkage between the amine group of cysteine (which is attached by normal peptide linkage to a glycine) and the carboxyl group of the glutamate side-chain. It is an antioxidant, preventing damage to important cellular components caused by reactive oxygen species such as free radicals and peroxides. [Wikipedia]. Glutathione is found in many foods, some of which are cashew nut, epazote, ucuhuba, and canada blueberry. Glutathione. CAS Common Chemistry.

Quinone is also called 1,4-benzoquinone or cyclohexadienedione. Quinones are oxidized derivatives of aromatic compounds and are often readily made from reactive aromatic compounds with electron-donating substituents such as phenols and catechols, which increase the nucleophilicity of the ring and contributes to the large redox potential needed to break aromaticity. Derivatives of quinones are common constituents of biologically relevant molecules. Some serve as electron acceptors in electron transport chains such as those in photosynthesis (plastoquinone, phylloquinone), and aerobic respiration (ubiquinone). Quinone is a common constituent of biologically relevant molecules (e.g. Vitamin K1 is phylloquinone). A natural example of quinones as oxidizing agents is the spray of bombardier beetles. Hydroquinone is reacted with hydrogen peroxide to produce a fiery blast of steam, a strong deterent in the animal world. 1,4-Benzoquinone, commonly known as para-quinone or quinone, is a chemical compound with the formula C6H4O2. 1,4-Benzoquinone is found in barley, olive, and anise.

Selenium

Selenium ion (se2+)

Se (79.9165)


Selenium-dependent enzymes and selenoprotein P regulate immune and endothelial cell function. (PMID: 16607122). Thyroid hormone synthesis, metabolism and action require adequate availability of the essential trace elements iodine and selenium, which affect homeostasis of thyroid hormone-dependent metabolic pathways. The three selenocysteine-containing iodothyronine deiodinases constitute a novel gene family. Selenium is retained and deiodinase expression is maintained at almost normal levels in the thyroid gland, the brain and several other endocrine tissues during selenium deficiency, thus guaranteeing adequate local and systemic levels of the active thyroid hormone T(3). (PMID: 16131327). The trace element nutrient selenium (Se) discharges its well-known nutritional antioxidant activity through the Se-dependent glutathione peroxidases. It also regulates nuclear factor activities by redox mechanisms through the selenoprotein thioredoxin reductases. Converging data from epidemiological, ecological, and clinical studies have shown that Se can decrease the risk for some types of human cancers, especially those of the prostate, lung, and colon. Mechanistic studies have indicated that the methylselenol metabolite pool has many desirable attributes of chemoprevention, targeting both cancer cells and vascular endothelial cells, whereas the hydrogen selenide pool in excess of selenoprotein synthesis can lead to DNA single strand breaks, which may be mediated by some reactive oxygen species. (PMID: 16356132). SePP (selenoprotein P) is the major transporter of Se in the serum. Moreover, in the sanctuary area of the brain, SePP was shown to play a hitherto unexpected role as a local Se storage and recycling protein that directly maintains brain Se levels. Physiologically, it exists as an ion in the body. The function of Se is important in normal brain metabolism, redox regulation, antioxidant defenses, thyroid hormone metabolism and the development of neurodegenerative conditions. (PMID: 15720294). In areas where soils are low in bioavailable selenium (Se), potential Se deficiencies cause health risks for humans. (PMID: 16028492) Dietary selenium comes from cereals, meat, fish, and eggs. The recommended dietary allowance for adults is 55 micrograms per day.

Buthionine sulfoximine

2-amino-4-[butyl(imino)oxo-lambda6-sulfanyl]butanoic acid

C8H18N2O3S (222.1038)


Buthionine Sulfoximine is a synthetic amino acid. Buthionine sulfoximine irreversibly inhibits gamma-glutamylcysteine synthase, thereby depleting cells of glutathione, a metabolite that plays a critical role in protecting cells against oxidative stress, and resulting in free radical-induced apoptosis. Elevated glutathione levels are associated with tumor cell resistance to alkylating agents and platinum compounds. By depleting cells of glutathione, this agent may enhance the in vitro and in vivo cytotoxicities of various chemotherapeutic agents in drug-resistant tumors. Buthionine sulfoximine may also exhibit antiangiogenesis activity.

Selenocystine

2-amino-3-[(2-amino-2-carboxyethyl)diselanyl]propanoic acid

C6H12N2O4Se2 (335.9127)


Selenocystine, also known as 3,3-diselenodialanine, belongs to the class of organic compounds known as alpha-amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxyl group (alpha carbon). More specifically, selenocystine is a diselenide consisting of two selenoamino acids that are attached together at their selenium atoms. This particular selenoamino acid is selenocysteine, the selenium analogue to cysteine (selenium being the element directly beneath sulphur in the periodic table); likewise, selenocystine is the selenium analogue to cystine. Since each constituent amino acid has a stereocentre, there are three different stereoisomers of selenocystine: D-selenocystine, L-selenocystine, and meso-selenocystine, the first two of which are optically active. Like other amino acids, L-selenocystine is the most common form within organisms; however, the D- and meso- forms have also been found (PMID: 30920149). Selenocystine is a solid that is moderately soluble in water. Due to the reactivity of selenocysteine, it is rarely encountered; rather, cells store selenium in the less reactive oxidized form of selenocystine or in a methylated form, such as selenomethionine (DOI: 10.1007/978-3-319-92405-2_3). When cells are grown in the absence of selenium, translation of selenoproteins terminates at the UGA codon, resulting in a truncated, non-functional enzyme. Unlike other amino acids present in biological proteins, selenocysteine is not coded for directly in the genetic code. Rather, the tRNA-bound seryl residue is converted to a selenocysteine residue by the pyridoxal phosphate-containing enzyme selenocysteine synthase (PMID: 17194211). Kurt Franke et al. indicated that there was evidence that selenium was in a form similar to that of cysteine, predating Thressa Stadtman’s discovery of the 21st amino acid by four decades (PMID: 26949981; J. Biol. Chem. 111:643). Selenocysteine may be denoted by the short forms Sec, U, or SeCys (Cys is used for cysteine), whereas selenocystine may be denoted by SeCys2. However, the literature sometimes uses SeCys for selenocystine and may cause confusion. Selenocystine has been found in animals, plants, and bacteria. It is being researched as treatment for cancer and for its antioxidant properties (PMID: 24763048, 24030774). Selenium, in its various forms such as selenocystine, is essential for many species, including humans, yet it is also toxic to all organisms; hence, it has come to be referred to as the “essential poison” (PMID: 26949981; 6679541). Selenocystine is a substrate for glutathione peroxidase 1. [HMDB] D000890 - Anti-Infective Agents > D000998 - Antiviral Agents L-Selenocystine is a diselenide-bridged amino acid. L-Selenocystine is a redox-active selenium compound that has both anti- and pro-oxidant actions.

C20H32O4 (336.23)


15(S)-hydroperoxyeicosatetraenoic acid (15(S)-HPETE) is the corresponding hydroperoxide of 15(S)-HETE and undergoes homolytic decomposition to the DNA-reactive bifunctional electrophile 4-oxo-2(E)-nonenal, a precursor of heptanone-etheno-2-deoxyguanosine. Reactive oxygen species convert the omega-6 polyunsaturated fatty acid arachidonic acid into (15-HPETE); vitamin C mediates 15(S)-HPETE decomposition. 15(S)-HPETE initiates apoptosis in vascular smooth muscle cells. 15(S)-HPETE is a lipoxygenase metabolite that affects the expression of cell adhesion molecules (CAMs) involved in the adhesion of leukocytes and/or the accumulation of leukocytes in the vascular endothelium, these being the initial events in endothelial cell injury. 15(S)-HPETE induces a loss of cardiomyocytes membrane integrity. 15-(S)HPETE is a hydroperoxide that enhances the activity of the enzymes lipoxygenase [EC 1.13.11.12] and Na+, K+-ATPase [EC 3.6.3.9] of brain microvessels. Lipoxygenase(s) and Na+-K+-ATPase of brain microvessels may play a significant role in the occurrence of ischemic brain edema. (PMID: 15964853, 15723435, 8655602, 8595608, 2662983).

Selenomethionine

L-SelenoMethionine

C5H11NO2Se (196.9955)


A selenoamino acid that is the selenium analogue of methionine. C26170 - Protective Agent > C275 - Antioxidant Selenomethionine, also known as (2s)-2-amino-4-(methylseleno)butanoate or 2-amino-4-(methylselenyl)butyric acid, is a member of the class of compounds known as alpha amino acids. Alpha amino acids are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Selenomethionine is soluble (in water) and a moderately acidic compound (based on its pKa). Selenomethionine can be found in a number of food items such as shiitake, canada blueberry, sesbania flower, and spearmint, which makes selenomethionine a potential biomarker for the consumption of these food products. Selenomethionine can be found primarily in blood and urine, as well as throughout most human tissues. Selenomethionine exists in all eukaryotes, ranging from yeast to humans. In humans, selenomethionine is involved in the selenoamino acid metabolism. Moreover, selenomethionine is found to be associated with prostate cancer. Selenomethionine is a naturally occurring amino acid. The L-selenomethionine enantiomer is the main form of selenium found in Brazil nuts, cereal grains, soybeans, and grassland legumes, while Se-methylselenocysteine, or its γ-glutamyl derivative, is the major form of selenium found in Astragalus, Allium, and Brassica species. In vivo, selenomethionine is randomly incorporated instead of methionine. Selenomethionine is readily oxidized . L-SelenoMethionine, an L-isomer of Selenomethionine, is a major natural food-form of selenium. L-SelenoMethionin is a cancer chemopreventive agent that can reduce cancer incidence by dietary supplementation and induce apoptosis of cancer cells. L-SelenoMethionine also can increase expression of glutathione peroxidase[1][2][3]. Selenomethionine is a naturally occurring amino acid containing selenium and is a common natural food source.
