Alpelisib (BYL-719) is an orally active PI3Kα-selective inhibitor that blocks the conversion of PIP2 to PIP3, thereby inhibiting pathways including PI3K/AKT/mTOR, MAPK/ERK, Notch and JAK-STAT. Alpelisib also induces apoptosis, G0/G1 phase arrest and senescence; it significantly inhibits the proliferation, self-renewal, stemness and epithelial-mesenchymal transition (EMT) of tumor cells, reduces cancer stem cell populations and decreases the expression of stem cell markers. Alpelisib not only enhances the sensitivity to Eribulin (HY-13442) and exerts a synergistic effect with Paclitaxel (HY-B0015), but may also induce drug resistance by upregulating the SGK3/GSK3β/β-catenin signaling pathway. Alpelisib can be applied to research related to breast cancer, gastric cancer and lipomas associated with PTEN hamartoma tumor syndrome.

    Customer Validation
     Combined Palbociclib- and Fulvestrant-resistant cells, M-S and T-S, and the corresponding resistant cells, MPF-R and TPF-R, were treated with different inhibitors of the PI3K/AKT/mTOR pathway including Alpelisib (HY-15244; Alp; 1 μM in M-S/MPF-R and 250 to 500 nM in T-S/TPF-R), Capivasertib (Cap; 250 to 500 nM in M-S/MPF-R and 100 nM in T-S/TPF-R), Sapanisertib (Sap; 10 nM in M-S/MPF-R and 5 nM in T-S/TPF-R), and Gedatolisib (HY-10681; Ged; 10 nM) in combination with Palbociclib (HY-50767; Palbo; 200 nM) and Fulvestrant (HY-13636; Fulv; 100 nM) (n = 3 independent biological replicates per group, performed in duplicates).

    Customer Validation
     Triple combination with Gedatolisib (HY-10681), Palbociclib (HY-50767), and Fulvestrant (HY-13636) effectively inhibits growth of PIK3CA-mutant ER+ tumor xenografts resistant to combined palbociclib and fulvestrant. MPF-R cells (1 × 106) resistant to combined palbociclib and fulvestrant were injected into the mammary fat pads of NOG CIEA mice, and tumors were allowed to establish for 2 weeks to a size of ≈30 mm3. Mice were then treated with the combination of Fulvestrant (100 mg/kg, sc weekly), Palbociclib (25 mg/kg, oral gavage daily), and Capivasertib (100 mg/kg, oral gavage daily; n = 6) or Alpelisib (HY-15244; 25 mg/kg, oral gavage daily; n = 5). Tumor size was measured weekly. Average tumor growth curves measured weekly and Tumor volumes measured after excision.
