Abstract:
Prostate cancer (PCa) is the most frequently diagnosed male malignant tumor and remains the second leading cause of male cancer mortality in the western countries. The second-generation antiandrogen enzalutamide (ENZa) can prolong survival time for patients with mCRPC. However, the overexpression of glucocorticoids receptor (GR) in mCRPC cells causes the resistance of antiandrogen and leads to the failure of androgen receptor (AR) targeting therapy. Herein, based on the chemical structures of antiandrogen and crystal structure of GR, we set up to develop GR/AR (GR and AR) dual antagonist by virtual screening and biological evaluation. We identified Z19 as a dual AR/GR antagonist. Z19 inhibited the transcription activity of both AR and GR, reducing both protein and mRNA level of the downstream proteins of GR and AR signaling, and provided a potential lead compound for the development of novel treatment agents of prostate cancer. Our work demonstrates that rational drug design is an efficient strategy in development of the GR/AR dual antagonist for the treatment of prostate cancer.
Insights
Researchers developed Z19, a dual antagonist targeting both androgen receptor (AR) and glucocorticoid receptor (GR). This novel compound shows potential in overcoming resistance to prostate cancer therapies, offering a new treatment strategy.
Area of Science:
- Oncology
- Pharmacology
- Drug Discovery
Background:
- Prostate cancer (PCa) is a leading cause of cancer mortality in men.
- Enzalutamide (ENZa), a second-generation antiandrogen, improves survival in metastatic castration-resistant prostate cancer (mCRPC).
- Glucocorticoid receptor (GR) overexpression in mCRPC leads to resistance against antiandrogen therapy and AR-targeting treatments.
Purpose of the Study:
- To develop a dual antagonist targeting both the androgen receptor (AR) and glucocorticoid receptor (GR).
- To identify novel therapeutic agents for prostate cancer by addressing antiandrogen resistance mechanisms.
Main Methods:
- Utilized virtual screening and biological evaluation based on antiandrogen chemical structures and GR crystal structure.
- Identified and characterized Z19 as a dual AR/GR antagonist.
Main Results:
- Z19 effectively inhibited the transcriptional activity of both AR and GR.
- Z19 reduced the protein and mRNA levels of downstream signaling molecules regulated by GR and AR.
- Z19 demonstrated potential as a lead compound for novel prostate cancer treatments.
Conclusions:
- Rational drug design is an effective strategy for developing dual AR/GR antagonists.
- Z19 represents a promising candidate for overcoming therapeutic resistance in prostate cancer.
- Targeting both AR and GR offers a potential new avenue for mCRPC treatment.
