Inhibition of Human Aromatase by Myosmine
Irene L. Doering,
Myosmine, a minor tobacco alkaloid widely occurring in food products of plant and animal origin, inhibits the conversion of testosterone to estradiol by human aromatase (IC50: 33±2 μM) sevenfold more potent than nicotine (IC50: 223±10 μM) and may have implications for sexual hormone homoeostasis.
