ARN-509 (Cat No.:I005661) is a next-generation androgen receptor inhibitor used in the treatment of non-metastatic castration-resistant prostate cancer (nmCRPC) and metastatic hormone-sensitive prostate cancer (mHSPC). It works by blocking the androgen receptor signaling pathway, which is essential for the growth and survival of prostate cancer cells. ARN-509 prevents androgen receptor activation by androgens, leading to decreased tumor cell proliferation. Its high specificity and potency reduce the risk of off-target effects. Apalutamide has been shown to significantly improve progression-free survival in patients, offering an effective treatment for advanced prostate cancer.
