Based on 1 Customer Validation
2',4-Dihydroxychalcone is an orally active natural chalcone flavonoid. 2',4-Dihydroxychalcone restores intestinal barrier integrity by upregulating tight junction proteins, regulates intestinal flora balance and alleviates inflammation. 2',4-Dihydroxychalcone induces GPX4 degradation, ferroptosis and apoptosis, triggers cell cycle arrest, and exhibits broad anti-tumor activity. 2',4-Dihydroxychalcone also possesses antifungal activity, antileishmanial activity, and reduces the hemolytic effect and virulence of Vibrio vulnificus.
