The AR is important for therapeutic target in prostate cancer , thus many different inhibitors have been developed, primarily targeting the ligand binding domain of the protein, while inhibitors that target the N-terminal domain of the protein are still under development.  AR ligands can either be classified based on their structure ( steroidal or nonsteroidal ) or based on their ability to activate or inhibit transcription ( agonists or antagonists ).  Sulforaphane , a phytochemical derived from broccoli or the HSP90 inhibitor ganetespib or the NRF2 activator bardoxolone methyl has been shown to degrade both AR and AR-V7 and thus enhance the efficacy of antagonists like enzalutamide.  
SPL documents contain both the content of labeling (all text, tables and figures) for a product along with additional machine readable information (including drug listing data elements and clinical data elements). Drug listing data elements include coded information about the product (including product and generic names, ingredients, ingredient strengths, dosage forms, routes of administration, appearance, DEA schedule) and the packaging (package quantity and type). Clinical data elements include coded information about the clinical use of the product (including indications and use, contraindications, drug interactions, warning and precautions and use in special populations).
