Biological context of Flavonoid

  • Taken together, these results show for the first time, to our knowledge, that quercetin and isorhamnetin prevent AngII-induced endothelial dysfunction by inhibiting the overexpression of p47(phox) and the subsequent increased O(2)(-) production, resulting in increased nitric oxide bioavailability [11].
  • The structures of the flavonoid glycosides were analysed after alkaline hydrolysis, and were identified as 3-sophoroside/sophorotrioside-7-glucoside/sophoroside of kaempferol, quercetin and isorhamnetin (this last found in trace amount) [12].
  • Pretreatment with isorhamnetin resulted in remarkable increase of cell viability (P<0.05) and modulation of secretion disorders mediated by ox-LDL in a concentration-dependent manner [13].
  • These effects were obtained via inhibition of lectin-like ox-LDL receptor-1 upregulation, interference of ox-LDL-mediated intracellular signaling pathway (p38MAPK activation, NF-kappaB nuclear translocation, eNOS expression) and the antioxidant activity of isorhamnetin [13].
  • The corresponding mean values for isorhamnetin area under the curver (AUC) from 0 to 60 h were 838.2, 1262.8, 1623.4 ng . h . mL(-1) [3].
