R)-Bicalutamide is the (R)-enantiomer of Bicalutamide . (R)-Bicalutamide is an androgen receptor (AR) antagonist, with antineoplastic activity. (R)-Bicalutamide is widely used for the research of prostate cancer[1][2].

Bicalutamide is available as a racemic mixture. The R isomer (R-bicalutamide) has an ≈30-fold higher binding affinity to the AR than the S isomer[1].(R)-bicalutamide (0.02-20 μM) reduces na?ve LNCaP cells survival in a dose-dependent[2]. Cell Proliferation Assay[2] Cell Line: LNCaP cells, LNCaP-Rbic cells

(R)-Bicalutamide (10 mg/kg; i.g.; daily; for 4 days) has antitumor efficacy in VCaP xenografts mice[3]. Animal Model: CD1 male nude (nu/nu) mice, with VCaP xenografts[3]
