FL442

FL442 is an Androgen Receptor (AR) modulator. This compound exhibits potent inhibitory effects in AR-dependent prostate cancer cells, showing similar suppression efficiency to the traditional antiandrogen drugs Bicalutamide and Enzalutamide. It also maintains antiandrogen activity against the Enzalutamide-resistant AR mutant F876L. The pharmacokinetic properties of FL442 in mice reveal a longer half-life (8 hours), excellent targeting (prostate tissue), and metabolic stability. Additionally, it is effective at inhibiting LNCaP tumor growth at low plasma concentrations (30 ng/mL) .
