MCF7 cells were pretreated with or without 25, 50 μmol/L Etomoxir for 24 h.
Product was diluted to 20 uM in tissue culture and various cancer cells were treated for 18-30 h at this concentration. Enzyme activity was measured by flow cytometry after. Results were strongly replicable.
Etomoxir shows good solubility profile when diluted from 20 mM stock in DMSO. Does not cause cell death across cell lines at 20 uM.
Exogenous application on acute brain slices
Pre-incubation of 15 minutes at 100 uM
