Varilutamide
Varilutamide (ONC1-13B) is an orally active, brain-penetrant androgen receptor (AR) inhibitor. Varilutamide shows a rat AR IC50 of 7.9 μM, inhibits DHT-stimulated PSA expression and prostate cancer cell proliferation, suppresses tumor growth and PSA expression and weakly induces lower CYP3A activity. Varilutamide can be used for the research of castration-resistant prostate cancer and prostate cancer.

Varilutamide (ONC1-13B) (1 nM-10 μM; 24 h) potently inhibits DHT-induced PSA expression in LNCaP prostate cancer cells[1].
Varilutamide (1 nM-10 μM; 5 days) inhibits DHT-induced proliferation of LNCaP prostate cancer cells with an IC50 of 30 nM[1].
Varilutamide (1 nM-100 μM) binds to rat androgen receptor ligand-binding domain with an IC50 of 7.9 μM[1].
Varilutamide (1 nM-100 μM) acts as a full androgen receptor antagonist, inhibiting ligand-dependent coactivator recruitment with an IC50 of 19.9 μM without inducing coactivator recruitment on its own[1].
Varilutamide (10 μM; 60 min) inhibits [3H] GABA binding to rat cerebral cortex membrane homogenates by 42%[1].
Varilutamide (1-10 μM; 48 h) induces CYP3A activity in human cryopreserved hepatocytes at 10 μM but shows no significant induction at 1 μM[1].
