Metabolite Identification
Common NameFluoxymesterone
DescriptionFluoxymesterone is only found in individuals that have used or taken this drug. It is an anabolic steroid that has been used in the treatment of male hypogonadism, delayed puberty in males, and in the treatment of breast neoplasms in women. [PubChem]Fluoxymesterone is a synthetic androgenic anabolic steroid and is approximately 5 times as potent as natural methyltestosterone. Like testosterone and other androgenic hormones, fluoxymesterone binds to the androgen receptor. It produces retention of nitrogen, sodium, potassium, and phosphorus; increases protein anabolism; decreases amino acid catabolism and decreased urinary excretion of calcium. The antitumour activity of fluoxymesterone appears related to reduction or competitive inhibition of prolactin receptors or estrogen receptors or production.

Enzymes

General function:
Involved in DNA binding
Specific function:
Steroid hormone receptors are ligand-activated transcription factors that regulate eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Transcription factor activity is modulated by bound coactivator and corepressor proteins. Transcription activation is down-regulated by NR0B2. Activated, but not phosphorylated, by HIPK3
