Methods and compositions for regulation of 5-.alpha.-reductase activity
Ainult registreeritud kasutajad saavad artikleid tõlkida
Logi sisse
TECHNICAL FIELD OF THE INVENTION
The present invention relates generally to compounds, compositions methods regulating the action and function of androgens and other steroid hormones by modulating the activity of steroid-reductases, including isozymes of 5.alpha.-reductases. More specifically, the
4-amino-17.beta.-(cyclopropyloxy)androst-4-en-3-one, 4-amino-17.beta.-(cyclopropylamino)androst-4-en-3-one and related compounds as C.sub.17-20 lyase and 5.alpha.-reductase
Ainult registreeritud kasutajad saavad artikleid tõlkida
Logi sisse
BACKGROUND OF THE INVENTION
The enzyme steroid C.sub.17,20 lyase cleaves the 17-20 carbon-carbon bond in steroids having a two carbon side chain at the 17.beta.-carbon position to form important precursor molecules to the formation of testosterone, 5.alpha.-dihydrotestosterone and the estrogens,
4-aza steroids
