Biological Activity

Description Mitotane (NCI-C04933), is an antineoplastic medication used in the treatment of adrenocortical carcinoma.
Sterol-O-Acyl Transferase 1 [5]
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. Mitotane does not interfere with thyroid hormone laboratory tests but directly reduces both secretory activity and cell viability on pituitary TSH-secreting mouse cells. [1] Mitotane induces adrenal cortex necrosis, mitochondrial membrane impairment, and irreversible binding to CYP proteins. Mitotane (10-40μM) inhibits basal and cAMP-induced cortisol secretion but does not cause cell death. Mitotane exhibits an inhibitory effect on the basal expression of StAR and P450scc protein. Mitotane (40 μM) significantly diminishes StAR, CYP11A1 and CYP21 mRNA expression. Mitotane (40μM) almost completely neutralizes this positive effect and returned 8-Br-cAMP-induced StAR, CYP11A1, CYP17 and CYP21 mRNA to control levels. [2] Mitotane and gemcitabine combinations show antagonistic effects and interfered with the gemcitabine-mediated inhibition of the S phase of the cell cycle in H295R cells. [3]

In vivo Mitotane (60 mg/kg) significantly decreases adrenal mitochondrial and microsomal "P-450" and microsomal protein contnet 34%, 55%, and 35% respectively in rats, within 3 hours. [4]


Cell Research:


- Collapse
  • Cell lines: NCI-H295 cells
  • Concentrations: 0-100 μM
  • Incubation Time: 24 or 72 h
  • Method:

    NCI-H295 cells (106/well) incubated with different concentrations of mitotane or diluent were collected and stained with fluorescein-isothiocyanate-labeled Annexin V for 15 minutes and for 2 minutes with propidium iodide at RT. After washing, fluorescence was measured by flow cytometry using a FACSCalibur instrument and data analyzed with Cell Quest Pro. Viability testing using WST1 reagent was performed according to manufacturer's protocol

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
