A magic drug target: Androgen receptor.

Area of Science:

• Endocrinology
• Molecular Biology
• Pharmacology

Background:

• The androgen receptor (AR) plays a crucial role in various hormone-related diseases, including prostate, breast, ovarian, and pancreatic cancers, as well as anabolic deficiencies like muscle atrophy and osteoporosis.
• AR ligands, encompassing antagonists, agonists, and modulators, are explored as potential therapeutics, highlighting AR as a significant drug target.

Purpose of the Study:

• To review the structural characteristics of the androgen receptor (AR).
• To elucidate the rationale and methodologies for investigating AR as a drug target.
• To summarize representative antagonists and agonists targeting five distinct small molecule binding sites on AR.

Main Methods:

• Literature review of AR structure and function.
• Analysis of AR as a drug target in relevant diseases.
• Summary of small molecule ligands and their binding sites (ligand-binding pocket, activation function-2, binding function-3, DNA-binding domain, N-terminal domain).

Main Results:

• Detailed review of AR structural features relevant to drug development.
• Identification of five key small molecule binding sites on AR.
• Summary of current AR antagonists and agonists targeting these sites.

Conclusions:

• Androgen receptor (AR) is a critical target for treating hormone-related diseases.
• Understanding AR structure and ligand interactions is vital for developing novel therapeutics.
• Further research on AR and its ligands will advance the therapy of AR-dependent diseases.
