Beschreibung
Daidzein mainly comes from leguminous plants, the seeds of soybean (dadou), red
clover grass, or all Pueraria roots. Its medicinal value was first recorded in Shen
Nong Ben Cao Jing 2838 BC.?Daidzein, one of the main soy isoflavones, is also the
main component of radix puerariae (Gegen) which is the dry root of kudzu leguminous plants. Radix puerariae can reduce fever, produce saliva, and relieve diarrhea.
Its chemical composition is complicated, including puerarin, xyloside, soy flavonoids, soybean flavonoid glycosides, beta-sitosterol, daidzin, daidzein. The main
effective components are puerarin and daidzein
Chemische Eigenschaften
Off-White Crystalline Solid
Physikalische Eigenschaften
Appearance: pale-yellow prismatic crystal. Melting point: 315–323?°C. Solubility:
soluble in ethanol and ether
History
Daidzein is a kind of isoflavone compound, which was first synthetized by researchers in China. It has been widely used in drugs, food supplements, and cosmetics.
Because of two phenolic hydroxyl structures, Daidzein has poor water solubility,
poor liposolubility, and strong first-pass effect, leading to the low bioavailability of
oral absorption, which limits its widely clinical usage.
Ipriflavone is a kind of isoflavone modified from Daidzein, which has been used
for the treatment of osteoporosis in Japan and some European countries. The effects
of a series of amino alkoxy derivatives of ipriflavones on inhibiting the bone absorption were evaluated. The researchers found that 7-amino alkoxy derivative works
best. When Daidzein was alkylated or acylated at 7-hydroxyl selectively, the stability was increased, and thus the proliferation of MCF-7 cell was inhibited.
Verwenden
Inactive analog of Genistein (Cat. #G350000). Blocks the G1 phase of the cell cycle in Swiss 3T3 cells by inhibiting casein kinase II activity1.
Daidzein has also been shown to inhibit the action of GABA on recombinant GABAA receptors2.

Indications
Daidzein is mainly used for the treatment of hypertension, coronary heart disease,
cerebral thrombosis, and vertigo and aids in the treatment of sudden deafness. It can
also treat women with menopause syndrome.
Definition
ChEBI: A member of the class of 7-hydroxyisoflavones that is 7-hydroxyisoflavone substituted by an additional hydroxy group at position 4'.
Allgemeine Beschreibung
Daidzein is an endocrine-active estrogenic isoflavone. This phytoestrogen is capable to bind to estrogen to exert estrogenic effects in vivo. It can naturally be found in soybean seed and flour.
Biologische Aktivit?t
Analog of the phytoestrogen genistein (5,7-Dihydroxy-3-(4-hydroxyphenyl)-4H-1-benzopyran-4-one ). Blocks G 1 phase cell cycle progression and is an agonist at estrogen receptors.
Clinical Use
Daidzein can expand the coronary artery, femoral artery, and cerebral artery,
increase cerebral blood flow and limb blood circulation, reduce blood viscosity and
vascular resistance, decrease myocardial oxygen consumption, improve heartfunction, increase the microcirculation and blood flow to the tip, lower the blood
pressure, and adjust the heart rhythm. Daidzein can be used for the treatment of
hypertension, coronary heart disease, angina pectoris, myocardial infarction, cerebral thrombosis, dizziness, and sudden deafness. It can also be used for women’s
menopause syndrome.
