Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	Sterol-O-Acyl Transferase 1
In vitro	Mitotane inhibits both TSH expression and secretion, blocks TSH response to TRH, and reduces cell viability, inducing apoptosis at concentrations in the therapeutic window in the mouse TalphaT1 cell line. This compound does not interfere with thyroid hormone laboratory tests but directly reduces both secretory activity and cell viability on pituitary TSH-secreting mouse cells. It induces adrenal cortex necrosis, mitochondrial membrane impairment, and irreversible binding to CYP proteins. This chemical (10-40μM) inhibits basal and cAMP-induced cortisol secretion but does not cause cell death. It exhibits an inhibitory effect on the basal expression of StAR and P450scc protein. This agent (40 μM) significantly diminishes StAR, CYP11A1 and CYP21 mRNA expression. This compound (40μM) almost completely neutralizes this positive effect and returned 8-Br-cAMP-induced StAR, CYP11A1, CYP17 and CYP21 mRNA to control levels. Its combination with gemcitabine shows antagonistic effects and interfered with the gemcitabine-mediated inhibition of the S phase of the cell cycle in H295R cells.
In vivo	Mitotane (60 mg/kg) significantly decreases adrenal mitochondrial and microsomal "P-450" and microsomal protein content 34%, 55%, and 35% respectively in rats, within 3 hours.
