3-O-Methylquercetin Chemische Eigenschaften,Einsatz,Produktion Methoden

Beschreibung

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, antioxidant, antiallergy, and antimicrobial activity, and showed strong anti-viral activity inhibition of tomato ringspot virus.
3-O-Methylquercetin significantly inhibits cyclic adenosine monophosphate- (cAMP-) and cyclic guanosine monophosphate- (cGMP-) phosphodiesterase activity. 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.

Verwenden

A metabolite of the flavanoid Quercetin (Q509500) with inhibitory activity on lipopolysaccharide-induced activation of macrophage U937 cells.

Definition

ChEBI: A tetrahydroxyflavone having the 4-hydroxy groups located at the 3'- 4'- 5- and 7-positions as well as a methoxy group at the 2-position.

Biologische Aktivit?t

3-O-Methylquercetin isolated from the herbs of Croton cascarilloides. It is a selective and competitive PDE3/PDE4 inhibitor,and inhibits PDE3 than PDE4 with a low K(m) value; it inhibits total cAMP- and cGMP-phosphodiesterase (PDE) of guinea pig trachealis at low concentrations.
