3-O-Methylquercetin significantly inhibits cyclic adenosine monophosphate- (cAMP-) and cyclic guanosine monophosphate- (cGMP-) phosphodiesterase activity.[1] It possess anti-inflammatory, bronchodilating properties and used in treatment of asthma. It suppresses the total inflammatory cells, tumor necrosis factor-α (TNF-α) and attenuates the production of interleukins.[2]
3-O-Methylquercetin is a metabolite in flavone and flavonol biosynthesis. It is a naturally occurring compound present in various plants, and was shown to have potent anticancer-promoting[3], antioxidant[4], antiallergy[5], and antimicrobial activity[6], and showed strong anti-viral activity inhibition of tomato ringspot virus[7].

The aim of this study was to investigate the potential of quercetin and two of its "in vivo" metabolites, 3'-O-methyl quercetin and 4'-O-methyl quercetin, to protect H9c2 cardiomyoblasts against H(2)O(2)-induced oxidative stress. As limited data are available regarding the potential

Dietary antioxidants interact in a dynamic fashion, including recycling and sparing one another, to decrease oxidative stress. Limited information is available regarding the interrelationships in vivo between quercetin and vitamin E. We investigated the antioxidant activity and metabolism of quercetin

3,5-Dihydroxy-6,7,8-trimethoxyflavone, 3-O-methylquercetin, and helichrysetin were isolated from the flowers of the Rwandese medicinal plant, Helichrysum odoratissimum. Because of inconsistencies of the mp of the latter chalcone, a synthesis of helichrysetin was developed. 3-O-Methylquercetin was shown to be an active principle

Preguntas

  1. is this product also called Isorhamnetin?

    1 respuesta
    1. Isorhamnetin shares structural similarities with 3-O-methylquercetin. They are structural isomers, sharing similar chemical compositions but differing in the arrangement of atoms. Both compounds belong to the flavonoid family and have various dietary sources.

      For Item 90081, the structure and properties (SMILES string, InChI, InChI key) are of 3-O-methylquercetin per PubChem: https://pubchem.ncbi.nlm.nih.gov/compound/5280681.
