NCIt definition : An orally available selective androgen receptor (AR) downregulator (SARD), with potential
antineoplastic activity. Upon oral administration, AZD3514 binds to the AR ligand
binding domain and inhibits the binding of androgen, thereby preventing androgen-dependent
AR signaling. AZD3514 also causes downregulation of AR expression, which further prevents
AR-mediated signaling. This results in an inhibition of proliferation in AR-overexpressing
tumor cells. AR plays a key role in the proliferation of castration-resistant prostate
cancer cells.;
