Biological Activity

Orally active, potent aromatase (CYP19) inhibitor (IC50 values are 0.4 and 0.12 nM at rat ovary and human placenta cells respectively) that only weakly inhibits the synthesis of other steroid hormones. Reduces plasma estrogen levels into ranges induced by ovariectomy and inhibits testosterone-induced breast cancer cell growth in vitro (IC50 = 0.13 nM).

Preparing Stock Solutions

The following data is based on the product molecular weight 354.2. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 2.82 mL 14.12 mL 28.23 mL
5 mM 0.56 mL 2.82 mL 5.65 mL
10 mM 0.28 mL 1.41 mL 2.82 mL
50 mM 0.06 mL 0.28 mL 0.56 mL
