What is Anastrozole (Arimidex)?

Anastrozole (Arimidex) is a non-steroidal triazole aromatase inhibitor — reversibly blocks CYP19A1 with high selectivity. Reduces serum estradiol ~80–90% in research models. Widely used AI reference compound for estrogen suppression, aromatase pharmacology, and comparison vs steroidal AIs. Research use only.

Research Applications

Reversible Aromatase Inhibition

CYP19A1 competitive inhibition Ki, IC50, selectivity over other CYP enzymes

Estradiol Suppression Kinetics
