| IC50 | 11.23 µg/mL against MCF-7 | |
| Potency | 3,3'-di-O-Methylquercetin and 3-O-methylquercetin showed selective antiproliferative activity against MCF-7 cells, with IC(50) values of 10.11 and 11.23 µg/mL, respectively. | |
| Cell line/ mice model | MCF-7, Hep-2, Vero cell | |
| Additional information | Our results report for the first time the antiproliferative activity of naturally occurring 3,3′-di-O-methylquercetin. It seems that the presence of additional methyl group on position 3' did not improve the antiproliferative activity of 3,3′-di-O-methylquercetin compared with 3-O-methylquercetin. | |
