Is a metabolite of Estradiol. 16-Keto-17-β-estradiol, a potent estrogen, acts by binding to the estrogen receptor and impeding the binding of other estrogens. It exhibits efficacy in inhibiting the growth of Streptococcus faecalis, a bacterium detected in urine samples or associated with bacterial vaginosis. Moreover, 16-Keto-17-β-estradiol demonstrates anti-angiogenic properties, potentially attributable to its capacity to hinder angiogenic factors like vascular endothelial growth factor and angiopoietin 2. Additionally, this compound exerts hormonal effects on adrenocortical carcinoma cells, leading to reduced cell proliferation and enhanced apoptosis. Furthermore, it may possess anti-cancer attributes through the induction of apoptosis, suppression of tumor growth, inhibition of cancer cell proliferation, and stimulation of cancer cell death.
