Applications
|
In PC-3 cells co-transfected with ARE3-luciferase and wild type or mutant androgen receptor (AR), Abiraterone Acetate at the dose up to 25 μM did not any obvious increase in luciferase activity. However, Abiraterone Acetate dose-dependently inhibited stimulated wild type and mutant AR activity, with significant inhibition observed at the doses ≤ 10 μM.

Applications
|
Abiraterone Acetate at the dose of 0.5 mmol/kg/d resulted in serum concentrations ranging from 0.5 to 1 mmol/L. Compared with the control group, Abiraterone Acetate treatment significantly inhibited "castration-resistant" prostate cancer progression in the robustly growing subset, effectively inhibiting tumor growth over 4 weeks of treatment.
