Buparlisib (944396-07-0) is potent pan-Class I PI3-kinase inhibitor (IC50’s: p110α = 52 nM, p110? = 166 nM, p110δ = 116 nM. P110g = 262 nM).1,2 It inhibited microtubule dynamics at in vitro concentrations >1μM and doses above 50mg/kg in mice.3 Buparlisib lead to a precipitous drop in DNA synthesis in a mouse model of BRCA1-linked triple-negative breast cancer with less affect in normal tissue.4
A selective Class I PI3K inhibitor of p110α, p110β, p110δ and p110γ with IC50s of 50-300 nM.
NVP-BKM 120 is a novel anti-tumor active compound that is selective in that it inhibits specifically PI3 kinase activating cell death in glioma cells. Glioma cells being those that proliferate from tumors in the brain or the spine.
ChEBI: BKM120 is an aminopyridine that is 4-(trifluoromethyl)pyridin-2-amine substituted at position 5 by a 2,6-di(morpholin-4-yl)pyrimidin-4-y group. A selective PI3K inhibitor with anti-tumour properties. It has a role as an EC 2.7.1.137 (phosphatidylinositol 3-kinase) inhibitor and an antineoplastic agent. It is a member of morpholines, an aminopyrimidine, an aminopyridine and an organofluorine compound.
