The flavonoids diosmetin and luteolin exert synergistic cytostatic effects in human hepatoma HepG2 cells via CYP1A-catalyzed metabolism, activation of JNK and ERK and P53/P21 up-regulation.


Various types of tumors are known to overexpress enzymes belonging to the CYP1 family of cytochromes P450. The present study aimed to characterize the metabolism and further antiproliferative activity of the natural flavonoid diosmetin in the CYP1-expressing human hepatoma cell line HepG2. Diosmetin was converted to luteolin in HepG2 cells after 12 and 30 h… (More)
