||Arimidex (anastrozole) is an aromatase inhibitor, which inhibits estrogen synthesis (PMID: 29719441). Arimidex (anastrozole) is FDA approved for postmenopausal women with hormone receptor-positive early breast cancer or advanced patients who have failed tamoxifen therapy (FDA.gov).
||Afinitor (everolimus) binds to FKBP-12 and allosterically inhibits mTOR, leading to decreased mTORC1 signaling and potentially resulting in decreased tumor cell growth (PMID: 17766661, PMID: 28400999). Afinitor (everolimus) is FDA approved for use in neuroendocrine tumors of pancreatic, lung or gastrointestinal tract origin, advanced renal cell carcinoma, and in combination with Aromasin (exemestane) in hormone receptor-positive, HER2-negative breast cancer (FDA.gov).
Hormone - Anti-estrogens
||Faslodex (fulvestrant) is a competitive inhibitor of estrogen that binds and deforms estrogen receptors, and causes inhibition of growth in cultured estrogen-sensitive breast cancer cells (NCI Drug Dictionary). Faslodex (fulvestrant) is FDA approved for use in patients with hormone receptor-positive breast cancer (FDA.gov).
