Cell Line/Tissue: MCF7

MCF7 cells were pretreated with or without 25, 50 μmol/L Etomoxir for 24 h.

Efficiently blocks FA catabolism in cell culture.

Species: Human

Cell Line/Tissue: 293T

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.

CPT1 inhibition.
