ORM-15341 is a potent and full antagonist for human AR (hAR) with IC50 values of 38 nM as shown by transactivation assays in AR-HEK293 cells stably expressing full-length hAR and an androgen-responsive luciferase reporter gene construct.IC50 value: 38 nMTarget: androgen receptorin vitro: In competitive AR binding assays, the inhibition constant (Ki) values of ORM-15341 was 8 nM. ORM-15341 functions as a full antagonist for all tested mutant ARs , with IC50 of 25, 51, 700, and 1160 nM for wtAR, AR(F876L), AR(T877A), and AR(W741L).
