NVP-BKM120 is an orally bioavailable inhibitor of the class I PI3K isoforms p110α (IC50 = 52 nM) and p110β (IC50 = 166 nM). It is selective for these isoforms over the class III PI3K Vps34 (IC50 = 2,410 nM), the mammalian target of rapamycin (mTOR; IC50 = 2,866 nM), PI4Kβ (IC50 = >25,000 nM), and a variety of kinases (IC50s = >10,000 nM). NVP-BKM120 inhibits proliferation of human tumor and glioma cell lines, with p53 wild-type glioma cells being more sensitive than p53 mutant/deleted glioma cells (IC50s = 1.28 and 2.08 µM, respectively). It halts the cell cycle in the G2/M phase in both p53 wild-type and p53 mutant/deleted glioma cells, but p53 mutant/deleted cells reenter the cell cycle, progress into mitosis, and die via mitotic catastrophic cell death. NVP-BKM120 (1-5 mg/kg) crosses the blood brain barrier and selectively decreases phosphorylation of the PI3K target protein Akt. It increases survival in a U87 glioma mouse xenograft intracranial tumor model when administered orally at doses of 20 and 40 mg/kg once per week.

NVP-BKM120 inhibits colon cancer growth via FoxO3a-dependent PUMA induction
Oncotarget 2017 Sep 15;8(47):83052-83062.PMID:29137323DOI:10.18632/oncotarget.20943.
NVP-BKM120, a potent and highly selective PI3K inhibitor, is currently being investigated in phase I/II clinical trials. The mechanisms of action of NVP-BKM120 in colon cancer cells are unclear. In the present study, we investigated how NVP-BKM120 suppresses colon cancer cells growth and potentiates effects of other chemotherapeutic drugs. We found that NVP-BKM120 treatment enhance PUMA induction irrespective of p53 status through the FoxO3a pathway following AKT inhibition. Furthermore, PUMA is required for NVP-BKM120-induced apoptosis in colon cancer cells. In addition, NVP-BKM120 also synergized with 5-Fluorouracil or regorafenib to induce marked apoptosis via PUMA induction. Deficiency of PUMA suppressed apoptosis and antitumor effect of NVP-BKM120 in xenograft model. These results demonstrate a key role of PUMA in mediating the anticancer effects of NVP-BKM120 and suggest that PUMA could be used as an indicator of NVP-BKM120 sensitivity, and also have important implications for it clinical applications.
Inhibitory effect of NVP-BKM120 on cholangiocarcinoma cell growth
Oncol Lett 2018 Aug;16(2):1627-1633.PMID:30008846DOI:10.3892/ol.2018.8848.
Abnormal activation of the phosphatidylinositol 3-kinase (PI3K) pathway has been demonstrated in certain types of cancer, including cholangiocarcinoma (CCA). This pathway may therefore be a promising target for CCA treatment. The present study assessed the inhibitory effect of NVP-BKM120, a pan-class I PI3K inhibitor, on CCA cell growth. This inhibitory effect was determined using CCA cell lines and in CCA-inoculated mice. The result from sulforhodamine B (SRB) assay demonstrated that NVP-BKM120 treatment inhibited CCA cell growth in a dose-dependent manner, even at the lowest tested concentration. The in vivo study revealed that oral administration of NVP-BKM120 (10 or 30 mg/kg) to CCA-inoculated nude mice led to a reduction in tumor growth when compared with controls, which was indicated by an immunohistochemical assay for Ki67 expression. In addition, the result from TUNEL assay demonstrated that NVP-BKM120 induced cancer cell death without any signs of toxicity, which indicated by the body weight of mice (data not shown). Western blot analysis demonstrated that NVP-BKM120 inhibited CCA cell growth by suppressing RAC serine/threonine protein kinase/mechanistic target of rapamycin activation and inhibiting the phosphorylation of phosphatase and tensin homolog, which is the inactivation form of the negative regulator of this pathway. Therefore, the results of the present study indicated that NVP-BKM120 should be considered as a therapeutic agent against CCA that could be used to improve treatment.
Therapeutic potential of NVP-BKM120 in human osteosarcomas cells
J Cell Physiol 2019 Jul;234(7):10907-10917.PMID:30536897DOI:10.1002/jcp.27911.
Osteosarcoma (OS) is the most common pediatric malignant neoplasia of the skeletal system. It is characterized by a high degree of malignancy and a severe tendency to metastasize. In the past decade, many studies have provided evidence that the phosphoinositide 3-kinase (PI3K) signaling pathway is one of the most frequently altered pathways in human cancer, and has a critical role in driving tumor initiation and progression. Here, we have analyzed the therapeutic potential of the pan-PI3K inhibitor NVP-BKM120, which has recently entered clinical Phase II for treatment of PI3K-dependent cancers on three OS cell lines. We observed a concentration- and time-dependent decrease of Ser473 p-Akt as well as reduced levels of Thr37/46 p-4E-BP1, an indicator of the mammalian target of rapamycin complex 1 activity. All OS cell lines used in this study responded to BKM120 treatment with an arrest of cell proliferation, an increase in cell mortality, and an increase in caspase-3 activity. MG-63 cells were the most responsive cell line, demonstrating a significant increase in sub-G1 cells, and a rapid induction of cell death. Furthermore, we demonstrate that BKM120 is more effective when used in combination with other standard chemotherapeutic drugs. Combining BKM120 with vincristine demonstrated a more synergistic effect than BKM120 with doxorubicin in all the lines. Hence, we suggest that BKM120 may be a novel therapy for the treatment of OS presenting with anomalous upregulation of the PI3K signaling pathway.
Effects of PI3K inhibitor NVP-BKM120 on acquired resistance to gefitinib of human lung adenocarcinoma H1975 cells
J Huazhong Univ Sci Technolog Med Sci 2013 Dec;33(6):845-851.PMID:24337846DOI:10.1007/s11596-013-1209-5.
The effects of class I PI3K inhibitor NVP-BKM120 on cell proliferation, cell cycle distribution, cellular apoptosis, phosphorylation of several proteins of the PI3K/AKT signaling pathway and the mRNA expression levels of HIF1-α, VEGF and MMP9 in the acquired gefitinib resistant cell line H1975 were investigated, and whether NVP-BKM120 can overcome the acquired resistance caused by the EGFR T790M mutation and the underlying mechanism were explored. MTT assay was performed to detect the effect of gefitinib, NVP-BKM120, NVP-BKM120 plus 1 μmol/L gefitinib on growth of H1975 cells. The distribution of cell cycle and apoptosis rate of H1975 cells were examined by using flow cytometry. The mRNA expression levels of tumor-related genes such as HIF1-α, VEGF and MMP9 were detected by using real-time quantitative PCR. Western blotting was used to detect the expression level of phosphorylated proteins in the PI3K/AKT signaling pathway, such as Ser473-p-AKT, Ser235/236-p-S6 and Thr70-p-4E-BP1, as well as total AKT, S6 and 4E-BP1. The results showed that the NVP-BKM120 could inhibit the growth of H1975 cells in a concentration-dependent manner, and H1975 cells were more sensitive to NVP-BKM120 than gefitinib (IC50:1.385 vs. 15.09 μmol/L respectively), whereas combination of NVP-BKM120 and gefitinib (1 μmol/L) did not show more obvious effect than NVP-BKM120 used alone on inhibition of cell growth (P>0.05). NVP-BKM120 (1 μmol/L) increased the proportion of H1975 cells in G0-G1 phase and the effect was concentration-dependent, and 2 μmol/L NVP-BKM120 promoted apoptosis of H1975 cells. There was no significant difference in the proportion of H1975 cells in G0-G1 phase and apoptosis rate between NVP-BKM120-treated alone group and NVP-BKM120 plus genfitinib (1 μmol/L)-treated group or between DMSO-treated control group and gefitinib (1 μmol/L)-treated alone group (P>0.05 for all). It was also found that the mRNA expression levels of these genes were down-regulated by NVP-BKM120 (1 μmol/L), and NVP-BKM120 (1 μmol/L) or NVP-BKM120 (1 μmol/L) plus gefitinib (1 μmol/L) obviously inhibited the activation of Akt, S6 and 4E-BP1 as compared with control group, but single use of gefitinib (1 μmol/L) exerted no significant effect. These data suggested that NVP-BKM120 can overcome gefitinib resistance in H1975 cells, and the combination of NVP-BKM120 and gefitinib did not have additive or synergistic effects. It was also concluded that NVP-BKM120 could overcome the acquired resistance to gefitinib by down-regulating the phosphorylated protein in PI3K/AKT signal pathways in H1975 cells, but it could not enhance the sensitivity of H1975 cells to gefitinib.
Anti-tumor effects of NVP-BKM120 alone or in combination with MEK162 in biliary tract cancer
Cancer Lett 2017 Dec 28;411:162-170.PMID:29024814DOI:10.1016/j.canlet.2017.10.002.
There are currently no clinically validated therapeutic targets for biliary tract cancer (BTC). Despite promising results in other cancers, compounds targeting the phosphatidylinositol 3-kinase (PI3K)/AKT pathway, alone or in combination with Ras/Raf/MEK pathway inhibitors, have not been evaluated in BTC. Here, we examined the effects of a pan-PI3K inhibitor (BKM120) with or without a MEK inhibitor (MEK162), on eight human BTC cell lines carrying mutations in K-Ras and/or the PI3K catalytic subunit, PI3KCA. BKM120 inhibited the colony-forming ability and migration of BTC cells carrying wild-type (WT) PI3KCA and either mutant (MT) or WT K-Ras, but not of cells carrying mutations in both genes. In K-Ras-WT cells, BKM120 decreased the phosphorylation of Akt, its downstream effector kinase p70S6K, and the translational repressor 4E-BP1. Interestingly, BKM120 did not induce cell cycle arrest or suppress PI3K signaling via restoration of p-4E-BP1 in cells with PIK3CA and K-Ras double mutations. Notably, the resistance of dual K-Ras/PI3KCA-mutant cells to BKM120 was overcome by treatment with a combination of BKM120 and MEK162. Our findings thus support the clinical development of BKM120 monotherapy or BKM120/MEK162 combination therapy for the treatment of BTC.
