What is Nubeqa used for?

Nubeqa is a prescription medicine that is used to treat prostate cancer.


NUBEQA is an androgen receptor inhibitor. The chemical name is N-{(2S)-1-[3-(3-chloro-4-cyanophenyl)-1H-pyrazol-1-yl]propan-2-yl}-5-(1-hydroxyethyl)-1H-pyrazole-3-carboxamide.

The molecular weight is 398.85 and the molecular formula is C19H19Cl N6O2. The structural formula is:;

Darolutamide is an optically active with a specific rotation value [α]20D= 72.2 o*mL/(dm*g), white to greyish- or yellowish white crystalline powder, that is soluble in tetrahydrofuran, but practically insoluble in aqueous medium. Darolutamide has a pKa of 11.75.

NUBEQA (darolutamide) is supplied as film-coated tablets containing 300 mg of darolutamide for oral use. The inactive ingredients of the tablet are: calcium hydrogen phosphate, croscarmellose sodium, lactose monohydrate, magnesium stearate, povidone K 30, hypromellose 15 cP, macrogol 3350, and titanium dioxide.

Mechanism of Action

Darolutamide is an androgen receptor (AR) inhibitor. Darolutamide competitively inhibits androgen binding, AR nuclear translocation, and AR-mediated transcription. A major metabolite, keto-darolutamide, exhibited similar in vitro activity to darolutamide. In addition, darolutamide functioned as a progesterone receptor (PR) antagonist in vitro (approximately 1% activity compared to AR). Darolutamide decreased prostate cancer cell proliferation in vitro and tumor volume in mouse xenograft models of prostate cancer.
