Caffeic acid

(2E)-3-(3,4-dihydroxyphenyl)prop-2-enoic acid

C9H8O4 (180.0423)


Caffeic acid is a hydroxycinnamic acid that is cinnamic acid in which the phenyl ring is substituted by hydroxy groups at positions 3 and 4. It exists in cis and trans forms; the latter is the more common. It has a role as a plant metabolite, an EC 1.13.11.33 (arachidonate 15-lipoxygenase) inhibitor, an EC 2.5.1.18 (glutathione transferase) inhibitor, an EC 1.13.11.34 (arachidonate 5-lipoxygenase) inhibitor, an antioxidant and an EC 3.5.1.98 (histone deacetylase) inhibitor. It is a hydroxycinnamic acid and a member of catechols. Caffeic Acid is a natural product found in Pavetta indica, Eupatorium cannabinum, and other organisms with data available. Caffeic Acid is an orally bioavailable, hydroxycinnamic acid derivative and polyphenol, with potential anti-oxidant, anti-inflammatory, and antineoplastic activities. Upon administration, caffeic acid acts as an antioxidant and prevents oxidative stress, thereby preventing DNA damage induced by free radicals. Caffeic acid targets and inhibits the histone demethylase (HDM) oncoprotein gene amplified in squamous cell carcinoma 1 (GASC1; JMJD2C; KDM4C) and inhibits cancer cell proliferation. GASC1, a member of the KDM4 subgroup of Jumonji (Jmj) domain-containing proteins, demethylates trimethylated lysine 9 and lysine 36 on histone H3 (H3K9 and H3K36), and plays a key role in tumor cell development.

Lutein

(1R,4R)-4-[(1E,3E,5E,7E,9E,11E,13E,15E,17E)-18-[(4R)-4-hydroxy-2,6,6-trimethylcyclohex-1-en-1-yl]-3,7,12,16-tetramethyloctadeca-1,3,5,7,9,11,13,15,17-nonaen-1-yl]-3,5,5-trimethylcyclohex-2-en-1-ol

C40H56O2 (568.428)


Lutein is a common carotenoid xanthophyll found in nature. Carotenoids are among the most common pigments in nature and are natural lipid-soluble antioxidants. Lutein is one of the two carotenoids (the other is zeaxanthin) that accumulate in the eye lens and macular region of the retina with concentrations in the macula greater than those found in plasma and other tissues. Lutein and zeaxanthin have identical chemical formulas and are isomers, but they are not stereoisomers. The main difference between them is in the location of a double bond in one of the end rings. This difference gives lutein three chiral centers whereas zeaxanthin has two. A relationship between macular pigment optical density, a marker of lutein and zeaxanthin concentration in the macula, and lens optical density, an antecedent of cataractous changes, has been suggested. The xanthophylls may act to protect the eye from ultraviolet phototoxicity via quenching reactive oxygen species and/or other mechanisms. Some observational studies have shown that generous intakes of lutein and zeaxanthin, particularly from certain xanthophyll-rich foods like spinach, broccoli, and eggs, are associated with a significant reduction in the risk for cataracts (up to 20\\\\\%) and age-related macular degeneration (up to 40\\\\\%). While the pathophysiology of cataract and age-related macular degeneration is complex and contains both environmental and genetic components, research studies suggest dietary factors including antioxidant vitamins and xanthophylls may contribute to a reduction in the risk of these degenerative eye diseases. Further research is necessary to confirm these observations (PMID: 11023002). Lutein is a carotenol. It has a role as a food colouring and a plant metabolite. It derives from a hydride of a (6R)-beta,epsilon-carotene. Lutein is an xanthophyll and one of 600 known naturally occurring carotenoids. Lutein is synthesized only by plants and like other xanthophylls is found in high quantities in green leafy vegetables such as spinach, kale and yellow carrots. In green plants, xanthophylls act to modulate light energy and serve as non-photochemical quenching agents to deal with triplet chlorophyll (an excited form of chlorophyll), which is overproduced at very high light levels, during photosynthesis. Lutein is a natural product found in Eupatorium cannabinum, Hibiscus syriacus, and other organisms with data available. Lutein is lutein (LOO-teen) is a oxygenated carotenoid found in vegetables and fruits. lutein is found in the macula of the eye, where it is believed to act as a yellow filter. Lutein acts as an antioxidant, protecting cells against the damaging effects of free radicals. A xanthophyll found in the major LIGHT-HARVESTING PROTEIN COMPLEXES of plants.

beta-Cryptoxanthin

(1R)-3,5,5-trimethyl-4-[(1E,3E,5E,7E,9E,11E,13E,15E,17E)-3,7,12,16-tetramethyl-18-(2,6,6-trimethylcyclohex-1-en-1-yl)octadeca-1,3,5,7,9,11,13,15,17-nonaen-1-yl]cyclohex-3-en-1-ol

C40H56O (552.4331)


beta-Cryptoxanthin has been isolated from abalone, fish eggs, and many higher plants. beta-Cryptoxanthin is a major source of vitamin A, often second only to beta-carotene, and is present in fruits such as oranges, tangerines, and papayas (PMID: 8554331). Frequent intake of tropical fruits that are rich in beta-cryptoxanthin is associated with higher plasma beta-cryptoxanthin concentrations in Costa Rican adolescents. Papaya intake was the best food predictor of plasma beta-cryptoxanthin concentrations. Subjects that frequently consumed (i.e. greater or equal to 3 times/day) tropical fruits with at least 50 micro g/100 g beta-cryptoxanthin (e.g. papaya, tangerine, orange, watermelon) had twofold the plasma beta-cryptoxanthin concentrations of those with intakes of less than 4 times/week (PMID: 12368412). A modest increase in beta-cryptoxanthin intake, equivalent to one glass of freshly squeezed orange juice per day, is associated with a reduced risk of developing inflammatory disorders such as rheumatoid arthritis (PMID: 16087992). Higher prediagnostic serum levels of total carotenoids and beta-cryptoxanthin were associated with lower smoking-related lung cancer risk in middle-aged and older men in Shanghai, China (PMID: 11440962). Consistent with inhibition of the lung cancer cell growth, beta-cryptoxanthin induced the mRNA levels of retinoic acid receptor beta (RAR-beta) in BEAS-2B cells, although this effect was less pronounced in A549 cells. Furthermore, beta-cryptoxanthin transactivated the RAR-mediated transcription activity of the retinoic acid response element. These findings suggest a mechanism of anti-proliferative action of beta-cryptoxanthin and indicate that beta-cryptoxanthin may be a promising chemopreventive agent against lung cancer (PMID: 16841329). Cryptoxanthin is a natural carotenoid pigment. It has been isolated from a variety of sources including the petals and flowers of plants in the genus Physalis, orange rind, papaya, egg yolk, butter, apples, and bovine blood serum. In a pure form, cryptoxanthin is a red crystalline solid with a metallic lustre. It is freely soluble in chloroform, benzene, pyridine, and carbon disulfide. In the human body, cryptoxanthin is converted into vitamin A (retinol) and is therefore considered a provitamin A. As with other carotenoids, cryptoxanthin is an antioxidant and may help prevent free radical damage to cells and DNA, as well as stimulate the repair of oxidative damage to DNA. Structurally, cryptoxanthin is closely related to beta-carotene, with only the addition of a hydroxyl group. It is a member of the class of carotenoids known as xanthophylls. Beta-cryptoxanthin is a carotenol that exhibits antioxidant activity. It has been isolated from fruits such as papaya and oranges. It has a role as a provitamin A, an antioxidant, a biomarker and a plant metabolite. It derives from a hydride of a beta-carotene. beta-Cryptoxanthin is a natural product found in Hibiscus syriacus, Cladonia gracilis, and other organisms with data available.

C40H56O4 (600.4178)


Violaxanthin belongs to the class of organic compounds known as xanthophylls. These are carotenoids containing an oxygenated carotene backbone. Carotenes are characterized by the presence of two end-groups (mostly cyclohexene rings, but also cyclopentene rings or acyclic groups) linked by a long branched alkyl chain. Xanthophylls arise by oxygenation of the carotene backbone. Thus, violaxanthin is considered to be an isoprenoid lipid molecule. Violaxanthin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Violaxanthin is an orange-coloured pigment that is found in brown algae and various plants (e.g. pansies). It is biosynthesized from the epoxidation of zeaxanthin. Violaxanthin is a food additive that is only approved for use in Australia and New Zealand (INS: 161e) (PMID: 29890662). 3 (violaxanthin, zeaxanthin and antheraxanthin) participate in series of photo-induced interconversions known as violaxanthin cycle; Xanthophyll; a carotene epoxide that is precursor to capsanthin; cleavage of 9-cis-epoxycarotenoids (violaxanthin) to xanthoxin, catalyzed by 9-cis-epoxycarotenoid dioxygenase, is the key regulatory step of abscisic acid biosynthesis; one of 3 xanthophylls involved in evolution of plastids of green plants (oxygen evolution).

(3R,3R,6R,9-cis)-beta,epsilon-Carotene-3,3-diol is a carotenoid found in human fluids such as serum and breast milk (PMID: 9164160). Carotenoids are isoprenoid molecules that are widespread in nature and are typically seen as pigments in fruits, flowers, birds and crustacea. Animals are unable to synthesise carotenoids de novo, and rely upon the diet as a source of these compounds. Over recent years there has been considerable interest in dietary carotenoids with respect to their potential in alleviating age-related diseases in humans. This attention has been mirrored by significant advances in cloning most of the carotenoid genes and in the genetic manipulation of crop plants with the intention of increasing levels in the diet. Studies have shown an inverse relationship between the consumption of certain fruits and vegetables and the risk of epithelial cancer. Since carotenoids are among the micronutrients found in cancer preventive foods, detailed qualitative and quantitative determination of these compounds, particularly in fruits and vegetables and in human plasma, have recently become increasingly important (PMID: 1416048, 15003396).

D020011 - Protective Agents > D000975 - Antioxidants > D002338 - Carotenoids Cucurbitachrome 1 is a member of the class of compounds known as xanthophylls. Xanthophylls are carotenoids containing an oxygenated carotene backbone. Carotenes are characterized by the presence of two end-groups (mostly cyclohexene rings, but also cyclopentene rings or acyclic groups) linked by a long branched alkyl chain. Carotenes belonging form a subgroup of the carotenoids family. Xanthophylls arise by oxygenation of the carotene backbone. Cucurbitachrome 1 is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Cucurbitachrome 1 can be found in a number of food items such as italian sweet red pepper, herbs and spices, fruits, and red bell pepper, which makes cucurbitachrome 1 a potential biomarker for the consumption of these food products.
