Application

Hydroxyflutamide has been used:
  • as an androgen receptor antagonist to study its effects on cardiomyocyte hypertrophy induced by dihydrtestosterone (DHT) in primary neonatal rat ventricular cardiomyocyte and rat cardio myoblast (H9c2) cells.
  • as an androgen receptor antagonist for the treatment of MDA-kb2 cells to check its effect on luciferase expression.
  • as an antagonist control in transcriptional activation assay.

Biochem/physiol Actions

Hydroxflutamide is an AR antagonist. Androgen receptors (ARs) are nuclear hormone receptors/transcription factors. Hydroxyflutamide is an androgen antagonist with publications going back to 1981. It is one of a few gold standard AR antagonists; activities of new antagonists are measured against hydroxyflutamide.
Hydroxyflutamide plays a role in preventing the binding of 5α-dihydrotestosterone (DHT) and testosterone to the androgen receptors.
