Letrozole is an aromatase inhibitor approved by the US. Letrozole CGS 20267 is a third generation inhibitor of aromatase with IC50 of 007-20 nM in cell-free assaysIt has no effect on the plasma levels of 17α-OH progesterone thyroid-stimulating hormone TSH luteinizing hormone LH follicle-stimulating hormone FSH or androstenedione and does not affect normal urine electrolyte excretion or thyroid function in clinical. Letrozole selective inhibits estrogen biosynthesis and can be used for the research of breast cancer.
