生物活性

4′-Hydroxychalcone is a chalcone isolated from licorice root, with hepatoprotective activity. 4′-Hydroxychalcone inhibits TNFα-induced NF-κB activation via proteasome inhibition. 4′-Hydroxychalcone induces a rapid potassium release from mitochondrial vesicles and causes deterioration of respiratory control and oxidative phosphorylation of isolated rat liver mitochondria[1][2][3].

体外研究
(In Vitro)

4′-Hydroxychalcone (20-40 μM ; 2 hours) inhibits TNFα-induced (20 ng/mL; 6 hours) NF-kB pathway activation in a dose-dependent manner[3].
4′-Hydroxychalcone (0.1-25 μM ; 8 hours) inhibits proteasome activity in a dose-dependent manner but has no effect on IKK activity[3].
4′-Hydroxychalcone inhibits TNFα-dependent degradation of IkBα and subsequently prevents p50/p65 nuclear translocation leading to 4′-Hydroxychalcone-inhibited expression of NF-kB target genes[3].
4′-Hydroxychalcone affects cancer cell viability but has no significant effect on non-transformed cell viability[3].
