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.

体外研究

4'-Hydroxychalcone (20-40 μM ; 2 hours) inhibits TNFα-induced (20 ng/mL; 6 hours) NF-kB pathway activation in a dose-dependent manner.
4'-Hydroxychalcone (0.1-25 μM ; 8 hours) inhibits proteasome activity in a dose-dependent manner but has no effect on IKK activity.
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.
4'-Hydroxychalcone affects cancer cell viability but has no significant effect on non-transformed cell viability.
