使用
Ellagic Acid is a phenol antioxidant found naturally in various fruits and vegetables. Ellagic Acid was shown to exhibit high levels of hemostatic, antineoplastic, antimutagenic, antiproliferative and antioxidant properties in studies, which suggests its potential health benefits following ellagic acid consumption.
主な応用
Ellagic acid is used in medicine and cosmetics, as an antioxidant, and has anti-cancer and anti-viral effects.
Ellagic acid, a common plant polyphenol, is an inhibitor of glutathione S-transferase with Exhibits antitumor activity. It can be used for the determination of factor XIIa in plasma. Contact activation can occur in blood coagulation. It is also used as selective, ATP-competitive inhibitor of casein kinase 2 and a Topo I and II, FGR, GSK, and PKA inhibitor.
定義
ChEBI: Ellagic acid is an organic heterotetracyclic compound resulting from the formal dimerisation of gallic acid by oxidative aromatic coupling with intramolecular lactonisation of both carboxylic acid groups of the resulting biaryl. It is found in many fruits and vegetables, including raspberries, strawberries, cranberries, and pomegranates. It has a role as an antioxidant, a food additive, a plant metabolite, an EC 5.99.1.2 (DNA topoisomerase) inhibitor, an EC 5.99.1.3 [DNA topoisomerase (ATP-hydrolysing)] inhibitor, an EC 1.14.18.1 (tyrosinase) inhibitor, an EC 2.3.1.5 (arylamine N-acetyltransferase) inhibitor, an EC 2.4.1.1 (glycogen phosphorylase) inhibitor, an EC 2.5.1.18 (glutathione transferase) inhibitor, an EC 2.7.1.127 (inositol-trisphosphate 3-kinase) inhibitor, an EC 2.7.1.151 (inositol-polyphosphate multikinase) inhibitor, an EC 2.7.4.6 (nucleoside-diphosphate kinase) inhibitor, a skin lightening agent, a fungal metabolite, an EC 2.7.7.7 (DNA-directed DNA polymerase) inhibitor and a geroprotector. It is an organic heterotetracyclic compound, a cyclic ketone, a lactone, a member of catechols and a polyphenol. It is functionally related to a gallic acid.
製造方法
Ellagic acid is mainly extracted from plants, and it is present in several fruits such as cranberries, strawberries, raspberries, and pomegranates. Usually, the raw materials are degreasing and then extracted with an alkaline aqueous solution or extracted with ethanol. Then, after removing water-soluble proteins and gliadins, the sugar ligands can be decomposed by enzymes to obtain purer ellagic acid.
一般的な説明
Cream-colored needles (from pyridine) or yellow powder. Odorless.
空気と水の反応
Insoluble in water.
反応プロフィール
Ellagic acid reacts as a weak acid. Incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated. Heat is also generated by the acid-base reaction between phenols and bases. May be sulfonated exothermically very readily (for example, by concentrated sulfuric acid at room temperature). May be nitrated very rapidly, even by dilute nitric acid.
火災危険
Flash point data for Ellagic acid are not available; however, Ellagic acid is probably combustible.
生物活性
Selective, ATP-competitive inhibitor of casein kinase 2 (CK2) (IC 50 values are 40, 2900, 3500, 4300 and 9400 nM for CK2, Lyn, PKA, Syk? and FGR respectively). Exhibits antioxidant, antitumor and anticarcinogenic activity and also inhibits glutathione S-transferase.
抗がん研究
Ellagic acid is a naturally occurring phenolic constituent present in natural productsand nuts, most elevated amounts of which are found in raspberries (Daniel et al.1990). EA is considered as a potent anticarcinogenic and antimutagenic compound.EA shows anti-angiogenic property by repressing PDGF-R movement and phosphorylationof its substrate. It can intrude with endothelial cell-associated VEGR-2phosphorylation bringing about the restraint of the downstream signaling activatedby this receptor and in the hindrance of two key events fundamental in angiogenesis,i.e., EC movement and morphogenic separation into capillary-like structure. In parallel,EA indicated robust inhibitory activity against perivascular cells through itsrestraint of PDGF-R action and signaling prompting hindrance of VSMC relocation(Labrecque et al. 2005).
It is a phenolic compound extracted from pomegranate. It is an antiproliferative andantioxidant compound (Murakami et al. 1996). It induces apoptosis in cancer cellsof the prostate and breast and prevents the process of metastasis in different cancers(Singh et al. 2016b).
純化方法
This antioxidant crystallises from pyridine. It forms a dark green solution in aqueous N NaOH. The tetraactetate dilactone crystallises from Ac2O, with m 340o. [Beilstein 19 H 261, 19 III/IV 3164, 19/7 V 108.]
