Cell Culture, Treatment & Working Concentration

Cell Lines	Assay Type	Concentration	Incubation Time	Activity Description
MDA-MB-453	Cell viability assay	0, 20, 40, 60, 80, and 100 µM	24, 48, and 72 hours	With increasing concentrations of fisetin (0, 20, 40, 60, 80, and 100 µM), there was a decrease observed in cell number in different time intervals (24, 48, and 72 hours).
SGC7901	Proliferation assay	0, 1, 5, 10, 15 or 20 µM	48 h	inhibits proliferation
A549	Cell viability assay	0, 10, 20, 30 or 40 µM	24, 48 or 72 h	fisetin was effective in inhibiting the growth of A549 cells in a dose- and time-dependent manner
ARPE-19	Cell migration assay	5 or 10 μM	24 h	pretreatment with fisetin markedly reduced cell migration in EGF-treated ARPE-19 cells
SCC-23	Cell viability assay	0-100 μM	24 h	fisetin significantly inhibited cell viability in a dose-dependent manner (significantly when the concentration is higher than 20 μM)
Tca-8113	Cell viability assay	0-100 μM	24 h	fisetin significantly inhibited cell viability in a dose-dependent manner (significantly when the concentration is higher than 20 μM)

Mechanism of Action

Targets/IC₅₀/Ki	Sirtuin
In vitro	Fisetin selectively kills SPiDER-β-Gal positive senescence neural cells in vitro.
In vivo	Oral administration of fisetin, a senolytic drug, reduces the number of senescent neural cells observed, the SASP expression level, and depressive behavior in MRL/lpr mice.
