Descripción

Aplicación

Letrozole has been used:

• in organoid growth assay to determine its inhibitory capacity(48)
• to investigate steroid receptor coactivator-1 (SRC-1) mediated endogenous estrogen regulation of hippocampal PSD-95(49)
• to determine its effects on tumor-induced hyperalgesia(50)
• for hormonal manipulation in rats(51)
• to study its effects on lipocalin-2 (Lcn2)(52)
• to determine its effects on mechanical hyperalgesia and aromatase expression(53)

Acciones bioquímicas o fisiológicas

Letrozole acts as an adjuvant agent and is used to treat breast cancer.

Letrozole is a non-steroidal aromatase inhibitor.

Letrozole is a third generation nonsteroidal aromatase inhibitor. It is a competitive inhibitor of the aromatase enzyme system and thus inhibits the conversion of androgens to estrogens. Letrozole inhibits the aromatase enzyme by competitively binding to the heme of the cytochrome P450 subunit of the enzyme, resulting in a reduction of estrogen biosynthesis in all tissues.
