Enzalutamide (ENZ) and apalutamide (APA) are two second-generation androgen receptor inhibitors (SGARIs) that have been primarily used in the treatment of prostate cancer. In conclusion, functional modulation of androgen receptor signaling leads to significant alterations in male zebrafish behavior, particularly affecting fear responses, aggression, and anxiety-related behaviors. We believe that these findings could contribute to a deeper understanding of the relationship between androgens and behaviors in vertebrates, especially zebrafish.
A 75-year-old man with mHSPC was treated with Apa and leuprorelin. Apa induced CYP3A4 via the PXR pathway, leading to a sustained DDI with CsA. Careful monitoring is necessary when Apa is coadministered with CYP3A4 substrates.

Mechanistically, while stimulation with the AR-agonist R1881 is sufficient to induce nuclear translocation of AR in AR+ TNBC cells, AR inhibition with enzalutamide, apalutamide, or darolutamide blocked AR nuclear translocation. These findings suggest that AR-mediated radioresistance is at least partially due to downstream MAPK/ERK signaling. Together this work builds on the mechanistic understanding of AR-mediated radioresistance in AR+ TNBC which may expose vulnerabilities in resistance to combination treatment with AR inhibition and RT.

This study developed and validated an LC-MS/MS method for simultaneous quantification of Talazoparib and Enzalutamide in rat plasma using Apalutamide as the internal standard. In pharmacokinetic studies on male Wistar rats, Talazoparib showed a Cmax of 0.88 ng/mL at 3 h and an AUC0-t of 20 ng·h/mL, while Enzalutamide exhibited a Cmax of 76.18 ng/mL at 1 h and an AUC0-t of 1702 ng·h/mL; both had 24 h half-lives. The validated method enables sensitive, rapid, and reliable bioanalysis for preclinical pharmacokinetic evaluation.
