Disease relevance of Rhapontigenin

 

High impact information on Rhapontigenin

 

Biological context of Rhapontigenin

  • Resveratrol (1) and rhapontigenin (5) demonstrated significant inhibitions upon the release of beta-hexosaminidase from the cultured RBL-2H3 cells in a dose-dependent manner and the IC50 values were calculated as 14 and 15 microM, respectively [7].
  • We have further investigated the inhibition kinetics of P450 1A1 by rhapontigenin [5].
  • Rhapontigenin intravenous dosing yielded the plasma AUC, urine t(1/2), CL and V(d) values of 8.39+/-0.10 mug h mL(-1), 25.31+/-1.46 h, 1.18+/-0.035 Lh(-1) kg(-1) and 11.05+/-0.17 L kg(-1)(mean+/-s.e.m.), respectively [6].
  • The obtained results show that rhapontigenin maintains significant cell viability in a dose-dependent manner and it exerts a protective effect on mitochondrial functionality, as evidenced by mitochondrial oxygen consumption experiments [1].
  • Rhapontigenin intraperitoneally administered showed the strongest inhibitory activity and significantly inhibited PCA at doses of 25 and 50 mg/kg, with inhibitory activities of 48 and 85%, respectively [2].
