Abstract:
The androgen receptor (AR), a ligand-dependent transcription factor that regulates the expression of a series of downstream target genes after the binding of androgens, has been a target for the discovery of drugs used to treat prostate cancer. Prostate cancer always progresses to castration-resistant prostate cancer after a period of androgen deprivation therapy. Thus, developing potent androgen receptor antagonists for the therapy of castration-resistant prostate cancer possesses great significance. This review summarizes the preclinical development of androgen receptor antagonists, conventional androgen receptor antagonists that competitively bind to the ligand binding domain of the androgen receptor and coactivator antagonists of the androgen receptor, including both activation function-2 antagonists and binding function-3 antagonists. We hope that this review can help other researchers find new scaffolds and sites for the treatment of prostate cancer.
Insights
This review covers androgen receptor (AR) antagonists for treating castration-resistant prostate cancer. It summarizes preclinical developments of AR antagonists, including conventional and coactivator types, to aid future drug discovery.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Androgen receptor (AR) is a key target in prostate cancer therapy.
- Prostate cancer often progresses to castration-resistant prostate cancer (CRPC) despite androgen deprivation therapy.
- Developing novel AR antagonists is crucial for effective CRPC treatment.
Purpose of the Study:
- To review the preclinical development of androgen receptor antagonists.
- To categorize AR antagonists into conventional and coactivator types.
- To identify new therapeutic strategies for prostate cancer.
Main Methods:
- Literature review of preclinical studies on AR antagonists.
- Classification of AR antagonists based on their mechanism of action (ligand binding domain competitive inhibitors, coactivator antagonists).
- Analysis of activation function-2 and binding function-3 antagonists.
Main Results:
- Summarized various classes of AR antagonists.
- Highlighted conventional AR antagonists that compete for AR ligand binding.
- Detailed coactivator antagonists, including AF-2 and BF-3 antagonists.
Conclusions:
- Preclinical development of AR antagonists shows promise for CRPC treatment.
- Understanding different antagonist classes can guide the discovery of new drug scaffolds.
- Further research into novel AR antagonist sites is needed for improved prostate cancer therapies.
