Ellagic acid

6,7,13,14-tetrahydroxy-2,9-dioxatetracyclo[6.6.2.0^{4,16}.0^{11,15}]hexadeca-1(14),4(16),5,7,11(15),12-hexaene-3,10-dione

C14H6O8 (302.0062676)


Ellagic acid appears as cream-colored needles (from pyridine) or yellow powder. Odorless. (NTP, 1992) 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. Ellagic acid is present in several fruits such as cranberries, strawberries, raspberries, and pomegranates. In pomegranates, there are several therapeutic compounds but ellagic acid is the most active and abundant. Ellagic acid is also present in vegetables. Ellagic acid is an investigational drug studied for treatment of Follicular Lymphoma (phase 2 trial), protection from brain injury of intrauterine growth restricted babies (phase 1 and 2 trial), improvement of cardiovascular function in adolescents who are obese (phase 2 trial), and topical treatment of solar lentigines. Ellagic acids therapeutic action mostly involves antioxidant and anti-proliferative effects. Ellagic acid is a natural product found in Fragaria chiloensis, Metrosideros perforata, and other organisms with data available. Ellagic acid is a metabolite found in or produced by Saccharomyces cerevisiae. A fused four ring compound occurring free or combined in galls. Isolated from the kino of Eucalyptus maculata Hook and E. Hemipholia F. Muell. Activates Factor XII of the blood clotting system which also causes kinin release; used in research and as a dye.

It is an organic heterotetracyclic compound, a cyclic ketone, a lactone, a member of catechols and a polyphenol. It derives from a gallic acid. Ellagic acid, also known as ellagate, belongs to the class of organic compounds known as hydrolyzable tannins. These are tannins with a structure characterized by either of the following models. In model 1, the structure contains galloyl units (in some cases, shikimic acid units) that are linked to diverse polyol carbohydrate-, catechin-, or triterpenoid units. In model 2, contains at least two galloyl units C-C coupled to each other, and do not contain a glycosidically linked catechin unit. The antiproliferative and antioxidant properties of ellagic acid have spurred preliminary research into the potential health benefits of ellagic acid consumption. Ellagic acids therapeutic action mostly involves antioxidant and anti-proliferative/anti-cancer effects. Ellagic acid is found, on average, in the highest concentration within a few different foods, such as chestnuts, common walnuts, and japanese walnuts and in a lower concentration in whiskies, arctic blackberries, and cloudberries. Ellagic acid has also been detected, but not quantified in several different foods, such as lowbush blueberries, bilberries, guava, strawberry guava, and bog bilberries. 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. Widely distributed in higher plants especies dicotyledons. Intestinal astringent, dietary role disputed. Nutriceutical with anticancer and antioxidation props. Ellagic acid is a natural antioxidant, and acts as a potent and ATP-competitive CK2 inhibitor, with an IC50 of 40 nM and a Ki of 20 nM.

C4H6N4O12 (301.9982236)


Erythrityl Tetranitrate is only found in individuals that have used or taken this drug. It is a vasodilator with general properties similar to nitroglycerin. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1020)Similar to other nitrites and organic nitrates, erythrityl tetranitrate is converted to an active intermediate compound which activates the enzyme guanylate cyclase. This stimulates the synthesis of cyclic guanosine 3,5-monophosphate (cGMP) which then activates a series of protein kinase-dependent phosphorylations in the smooth muscle cells, eventually resulting in the dephosphorylation of the myosin light chain of the smooth muscle fiber. The subsequent release of calcium ions results in the relaxation of the smooth muscle cells and vasodilation.

Malathion monocarboxylic acid is a metabolite of malathion. Malathion is an organophosphate parasympathomimetic which binds irreversibly to cholinesterase. Malathion is an insecticide of relatively low human toxicity; however, a 2010 study has shown that children with higher levels of organophosphate pesticide metabolites in their urine are more likely to have attention deficit hyperactivity disorder. In the former USSR it was known as carbophos, in New Zealand and Australia as maldison and in South Africa as mercaptothion. (Wikipedia)
