PI3K Inhibitor (Pan)
||Buparlisib (BKM120) specifically inhibits class I PI3K in the PI3K/AKT kinase (or protein kinase B) signaling pathway in an ATP-competitive manner, and may result in apoptotic activity and inhibition of cell proliferation (PMID: 22188813).
||Femara (letrozole) is an aromatase inhibitor, which inhibits estrogen synthesis (NCI Drug Dictionary). Femara (letrozole) is approved for postmenopausal women with hormone receptor positive breast cancer (FDA.gov).
||Kisqali (ribociclib) is a dual CDK4/6 inhibitor, which may induce cell cycle arrest and reduce proliferation in cancer cells (PMID: 24045179). Kisqali (ribociclib) is FDA-approved in combination with an aromatase inhibitor in women with hormone receptor-positive, ERBB2 (HER2)-negative breast cancer, and in combination with Faslodex (fulvestrant) in postmenopausal women with hormone receptor-positive, ERBB2 (HER2)-negative breast cancer (FDA.gov).
