Isoflavone is an isomer of flavone, which is chromone substituted with a phenyl group in the 2-position. [1] In isoflavone, the phenyl group is in the 3-position. [1] [5] Substituted isoflavone derivatives are related to the parent by the replacement of two or three hydrogen atoms with hydroxyl groups. [1] Isoflavone, numbering.
Therefore, they are depicted as C6-C3-C6 compounds. Depending on the chemical structure, degree of oxidation, and unsaturation of the linking chain (C3), flavonoids can be classified into different groups, such as anthocyanidins, flavonols, flavanones, flavan-3-ols, flavanonols, flavones, and isoflavones. [1]
While flavonoids (in the narrow sense) have the 2-phenylchromen-4-one backbone, isoflavonoids have the 3-phenylchromen-4-one backbone with no hydroxyl group substitution at position 2 (case of the isoflavones) or the 3-phenylchroman (isoflavan) backbone (case of isoflavanes, such as equol).
They have the 3-phenylchroman (isoflavan, CAS number: 4737-26-2, molecular formula: C 15 H 14 O, exact mass: 210.1044646 u) backbone. [1] Examples. Equol; References
Isoflavones such as genistein and daidzein are found in a number of plants including lupin, fava beans, soybeans, kudzu, and psoralea being the primary food source, [4] [5] also in the medicinal plants, Flemingia vestita [6] and F. macrophylla, [7] [8] and coffee. [9] It can also be found in Maackia amurensis cell cultures. [10]
CAS Number. 41743-56-0 ... Luteone is a prenylated isoflavone, a type of flavonoid. It can be found in the pods of Laburnum anagyroides [1] and can be synthesized. [2]
The new numbering of the resulting moiety is shown with red numbers. Pterocarpans are derivatives of isoflavonoids found in the family Fabaceae. It is a group of compounds which can be described as benzo-pyrano-furano-benzenes (i.e. 6H-[1]benzofuro[3,2-c]chromene skeleton) which can be formed by coupling of the B ring to the 4-one position.
