AZD3514 is primarily investigated for its potential in cancer therapy, particularly in the treatment of prostate cancer. It functions as an androgen receptor down-regulator, targeting the androgen receptor signaling pathway, which is crucial for the growth and survival of prostate cancer cells. By inhibiting this pathway, AZD3514 aims to reduce tumor growth and progression, especially in cases where the cancer has become resistant to standard treatments like hormone therapy. Its application is significant in advancing personalized medicine approaches for patients with advanced or castration-resistant prostate cancer, offering a potential therapeutic option when other treatments have failed.
