Flavonoidi

Quercetin 3-rhamnoside 7-glucoside is a naturally occurring flavonoid glycoside, which is derived from various plant sources, particularly those rich in flavonoids like fruits, vegetables, and leaves. This compound is characterized by its complex structure that includes quercetin linked to sugar moieties, specifically rhamnose and glucose, at the 3 and 7 positions.

5-Hydroxy-7,2',3',4',5'-pentamethoxyflavone is a flavone that can be found in coffee. It has been shown to inhibit the enzyme arabinose isomerase and psiadiarabin, which are involved in the conversion of sugar into energy in plants. 5-Hydroxy-7,2',3',4',5'-pentamethoxyflavone also inhibits the plant enzyme phytase, which breaks down phytic acid. Phytic acid is a naturally occurring substance that binds to minerals such as calcium and zinc, preventing their absorption by the body. This compound has not shown any significant activity against bacterial DNA gyrase or topoisomerase IV or human DNA gyrase or topoisomerase II.

Dihydroisoformononetin is an isoflavonoid compound, which is a type of phytoestrogen derived primarily from plant sources, such as legumes and certain medicinal herbs. This compound is of significant interest due to its structural similarity to estrogen, which allows it to interact with estrogen receptors in the body. Its mode of action involves modulating estrogenic activity by acting either as an agonist or antagonist, depending on the tissue context. Such dual behavior makes it an intriguing subject of study in endocrine research.

7,8-Dihydroxyflavanone is a naturally occurring flavonoid compound, which is typically sourced from various plant species. This compound is structurally characterized by two hydroxyl groups, which are crucial for its biochemical activity. Its mode of action primarily involves the modulation of cellular signaling pathways, including those related to oxidative stress and enzyme inhibition. By interfering with these pathways, 7,8-Dihydroxyflavanone exerts antioxidant and possibly anti-inflammatory effects.

R,S equol 4'-sulfate sodium salt is a synthetic derivative of equol, which is a type of flavonoid metabolite. This compound is primarily sourced from the biotransformation of the isoflavone daidzein through gut microbiota activity. As a sulfate salt, it is more soluble in aqueous environments, which may facilitate its use in various biological contexts.
