  • AN3CA (B), JHUEM2 (D), and MFE296 (H) cells were treated with the indicated doses of BGJ398 and BYL719 alone or in combination for 96 hours, and an SRB assay was subsequently performed.

    Mol Cancer Ther, 2017. Alpelisib (BYL719) purchased from Selleck.

    BYL719 induces Apoptosis in MM cells. The effect of increasing concentrations of BYL719 (0-2.5 umol/l) for 48 h on the apoptosis of MM1s cells. The effect of BYL719 on the apoptosis signalling; cleaved PARP, caspase 3, caspase 9 by Western blotting. MM, multple myeloma.

    Br J Haematol 2014 165(1), 89-101. Alpelisib (BYL719) purchased from Selleck.

  • A549 cell was trypsinized and plated at 50% confluence in DMEM. 16 hours later, BYL719 was added at final concentrations of 0, 1, 5, 10 and 20uM. Another 24 hours later, cells were harvested in RIPA with protease and phosphatase inhibitor cocktail. Total protein concentration was measured by BCA method. Lysates equivalent to 20ug total protein were subject to Western Blot, using total- AKT, pS473-AKT, pT286-CyclinD1 and beta-actin (internal control) antibodies.

Biological Activity

Description Alpelisib (BYL719) is a potent and selective PI3Kα inhibitor with IC50 of 5 nM in a cell-free assay, and minimal effect on PI3Kβ/γ/δ. Phase 2.
PI3Kα [1]
(Cell-free assay)
5 nM
In vitro

BYL719 inhibits the proliferation of breast cancer cell lines harboring PIK3CA mutations, correlating with inhibition of various downstream signaling components of the PI3K/Akt pathway. [1]

In vivo BYL719(>270 mg/d) shows statistically significant dose-dependent anti-tumor efficacy in PIK3CA mutant xenograft models in rodents. BYL719 has a low clearance, a half-life of 8.5 h and its exposure increases dose proportionally between 30mg/d and 450mg/d, displaying a low inter-individual variability in Cmax and AUC in human. BYL719(270mg/d) shows first signs of clinical efficacy include 1 confirmed partial response in a patient with ER+ breast cancer, and significant PET responses (PMR) and/or tumor shrinkage are achieved in 8 out of 17 evaluated patients.
