Compliance for Clinical Use

Mechanism and Biochemical Profile

ORM-15341 functions as a potent and full antagonist of the human androgen receptor (hAR) with an IC50 of 38 nM and a Ki of 8 nM, effectively blocking ligand binding and downstream AR-mediated transcriptional activation. This pathway inhibition disrupts androgen-dependent gene expression and suppresses cellular proliferation, directly contributing to tumor growth control in prostate cancer.
