BKM120 (NVP-BKM120, Buparlisib) Mechanism
BKM120 (NVP-BKM120, Buparlisib) Mechanism
The receptor-regulated class I PI3K are heterodimeric enzymes, consisting of a 110-kDa catalytic subunit and a regulatory subunit. Different from p110α, -β, and -δ isoforms, the p110γ isoform tightly binds to the p101 regulatory subunit. The p101 structure indicates that an N-terminal domain mediates heterodimerization with the p110γ subunit, and a C-terminal interaction domain mediates the binding to Gβγ complexes. ^[1] The ATP binding site of PI3K-gamma catalytic domain is located in a cleft between the N- and the C-terminal lobes of the catalytic domain.
BKM120 is a 2,6-dimorpholino pyrimidine derivative. The crystal structure indicates that BKM120 binds in the ATP-binding site of PI3K-gamma kinase domain. Specifically, 2-morpholino group makes an interaction via the hydrogen bond from the morpholine oxygenoxygen to the backbone amino group of Val882. The exocyclic nitrogen in the 6-position pyridyl substituent as a donor also forms two bonds to Asp841 and Asp964 in the catalytic region. In addition, a water molecule makes a hydrogen bond bridge between Tyr836 and Asp810, which acts as a hydrogen bond acceptor to interact with the 6-pyridyl endocyclic nitrogen. The binding mode results in greater affinity of PI3K enzyme for BKM120 than ATP. ^[2]

IC50	52 nM	116 nM	166 nM	262 nM	2.4 μM	View More
In vitro	BKM120 is not sensitive to Class III and Class IV PI3K's or PI4K. NVP-BKM120 shows great antiproliferation activity to PI3K deregulated cell lines including A2780, U87MG, MCF7 and DU145 with GI50 of 0.1-0.7 nM. ^[1] BKM120 induces multiple myeloma cells (ARP1, ARK, MM.1S, MM1.R and U266) apoptosis, which results in increased G1-phase cells and decreased S-phase cells. BKM120 induced CD138+ primary MM cell apoptosis and has significant lower cytotoxicity toward CD138− stromal cells. BKM120 exposure could cause upregulation of BimS and downregulation of XIAP. ^[2] BKM120 demonstrates antiproliferative activity in human gastric cancer cell lines by decreasing mTOR downstream signaling. BKM120 could increase either p-ERK or p-STAT3 in KRAS mutant gastric cancer cells. Combination with STAT3 blockade, BKM120 shows a synergism in cells harboring mutated KRAS by inducing apoptosis, but not in KRAS wild-type cells. ^[3] A recent study shows that BKM120 shows differential forms of cell death on the basis of p53 status of the cells with p53 wild-type cells undergoing apoptotic cell death and p53 mutant/deleted cells having a mitotic catastrophe cell death. BKM120 mediates mitotic catastrophe mainly through Aurora B kinase. ^[4]
In vivo	BKM120 completely inhibits pAktser473 in A2780 xenograft tumors at doses of 30, 60, or 100 mg/kg, respectively. BKM120 also shows antitumor activity against U87MG glioma model at doses of 30 and 60 mg/kg. ^[1] BKM120 treatment results in significantly reduced tumor volume and level of circulating human kappa chain at 5 μM/kg/day−1in ARP1 SCID mouse model, with prolonged survival. ^[2]

Kinase Assay: ^[1]

PI3K biochemical assay (ATP depletion assay)	BKM120 is dissolved in DMSO and directly distributed into a black 384-well plate at 1.25 µL per well. To start the reaction, 25 µL of 10 nM PI3 kinase and 5 µg/mL 1-α-phosphatidylinositol (PI) in assay buffer (10 mM Tris pH 7.5, 5 mM MgCl₂, 20 mM NaCl, 1 mM DTT and 0.05% CHAPS) are added into each well followed by 25 µL of 2 µM ATP in assay buffer. The reaction is performed until approx 50% of the ATP is depleted and then stopped by the addition of 25 µL of KinaseGlo solution. The stopped reaction is incubated for 5 minutes and the remaining ATP is then detected via luminescence.
