ジオスミン

化学的特性Diosmin is a natural flavonoid mainly present in the peel of some citrus fruits, such as oranges and lemons. Flavonoids are anti-inflammatory plant compounds that protect your body from free radicals and other unstable molecules. The most prevalent uses for Diosmin include hemorrhoids and leg sores caused by poor blood flow. Diosmin was first found in 1925 in the wort plant and has since been used as a natural treatment for hemorrhoids, varicose veins, venous insufficiency, leg ulcers, and other circulatory issues.

用途ジオスミン(英: Diosmin)はジオスメチンの7位にルチノースが結合したフラボノイド配糖体。柑橘類の果実に含まれている。。ジオスミンは血管保護作用があるとされ、慢性静脈不全、痔、リンパ水腫、静脈瘤に使用される。

説明Diosmin was separated from the root of Scrophularia nodosa L. in 1925. The root of Scrophularia nodosa L. has the function of nourishing, reducing fever, relieving internal heat, and detoxicating. It was firstly recorded in the Shen Nong’s Classic of Materia Medica, as a class of middle-grade drug and is currently recorded in the Ch.P 2015, Volume I. The natural resource was abundant in China, mainly provided from Zhejiang, Sichuan, Hubei, Anhui, and Jiangsu provinces. In the clinical practice, Scrophularia nodosa L. was employed to eliminate pathogenic heat from the blood. In the clinical indication, diosmin was mainly applied to treat fever, polydipsia, maculitis, gingivitis, amygdalitis, laryngopharyngitis, acute lymphadenitis, etc. It also has the biological function of antiplatelet aggregation and antitumor. The chemical components include iridoids, phenylpropanoid glycoside, flavonoids, and fatty acids.

来歴Diosmin was firstly introduced as a medicine in 1969. It was launched in France in 1987 with the product name “Alvenor.” As the protecting agent for blood vessel and therapeutic agent for chronic venous disease, diosmin has been used for over 30years in EuropeDiosmin is a typical flavonoid. It could be prepared from natural resources or semisynthesized from the natural product hesperidin by dehydrogenation reaction.

使用Diosmin is an agonist of the aryl hydrocarbon receptor (AhR) and exhibits anti-proliferative and anti-inflammatory. It is used in the treatment of venous disease, i.e., chronic venous insufficiency (CVI) and hemorrhoidal disease (HD). Diosmin also reduces capillary hyperpermeability and expression of endothelial adhesion molecules (ICAM1, VCAM1). It effectively inhibits the P-glycoprotein (Pgp)-mediated efflux in cells.

定義ChEBI: Diosmin is a disaccharide derivative that consists of diosmetin substituted by a 6-O-(alpha-L-rhamnopyranosyl)-beta-D-glucopyranosyl moiety at position 7 via a glycosidic linkage. It has a role as an antioxidant and an anti-inflammatory agent. It is a glycosyloxyflavone, a rutinoside, a disaccharide derivative, a monomethoxyflavone and a dihydroxyflavanone. It derives from a diosmetin.
