What is Exemestane (Aromasin)?

Exemestane (Aromasin) is a steroidal suicide aromatase inhibitor — irreversibly inactivates aromatase (CYP19A1) via covalent binding. Structurally similar to androstenedione. Research tool for aromatase enzymology, irreversible enzyme inactivation kinetics, estrogen suppression, and steroidal vs non-steroidal AI comparison. Research use only.

Research Applications

Irreversible Aromatase Inactivation

Suicide substrate kinetics, kcat/kinact determination, CYP19A1 covalent inhibition

Steroidal vs Non-Steroidal AI

Exemestane vs anastrozole/letrozole — mechanism, selectivity, recovery studies

Estrogen Suppression

Estradiol reduction kinetics, tissue estrogen levels, receptor occupancy

Bone Health Research

Estrogen-dependent bone turnover — aromatase inhibition effects on BMD

Post-Aromatase Recovery

New aromatase synthesis after irreversible inactivation — enzyme recovery timeline
