IC-87114 selectively inhibits PI3Kδ and not sensitive to PI3Kα, β, and γ. In human neutrophils, IC87114 (5 µM) potently inhibits N-formyl-methionyl-leucyl-phenylalanine (fMLP)-stimulated phosphatidylinositol triphosphate (PIP3) biosynthesis and chemotaxis. IC87114 (5 µM) also inhibits polarized morphology and spreading of neutrophils. [1] In human acute myeloid leukemia (AML) blast cells, such as bone marrow mononuclear cells (BMMCs), IC87114 (10 µM) inhibits both constitutive and Flt-3-stimulated Akt phosphorylation and cell proliferation. [2] It is also found that IC87114 (5 µM–30 µM) inhibits SCF- or IL-3-stimulated BMMC responses, which are not observed in PI3Kδ mutant (p110δD910A) cells. [3] In anti-CD3-stimulated mice CD62L+ (naive) and CD62L (effector/memory) CD4+ T cells, IC87114 inhibits proliferation and interferon-gamma (IFN-γ) production. The IC50 values of IC87114 are: (1) 1.2 µM and 40 nM, for CD62L+ and CD62L cell proliferation, respectively; (2) 120 nM and 1 nM, for IFN-γ production of CD62L+ and CD62L cells, respectively. Similar effects by IC87114 are also observed in human T cells. [4] A recent study reveals that in chromaffin cells, IC87114 enhances the transient increase of PtdIns(4,5)P2, which results in a potentiation of exocytosis. [5]

In vivo In mice, IC87114 (15 mg/kg–60 mg/kg) inhibits the allergic response in the back skin and ear. [3] In mice induced with anti-CD3 or ConA, IC87114 (30 mg/kg) reduces hypersensitivity responses and decreases plasma levels of cytokines, such as IL-2, IL-4, IL-17, IFN-γ, and tumor necrosis factor-α (TNF-α).

Protocol (from reference)

Kinase Assay:


  • PI3K kinase assay:

    Phosphatidylinositol-(4,5)-bisphosphate (PIP2) containing phospholipid liposomes are prepared. Briefly, bovine PIP2 and phosphatidylserine (1:2 molar ratio) are vacuum-dried and resuspended at 1 mM PIP2 in 20 mM HEPES-KOH, pH 7.4, 50 mM NaCl, and 5 mM EDTA. The lipid suspension is subjected to a brief sonication, followed by 5 freeze-thaw cycles and then 20 extrusion cycles to produce the liposomes. The assay is conducted in 60 μL reaction volumes in 20 mM HEPES, pH 7.4, buffer containing 1 nM PI3K, 1 µM PIP2, 200 µM ATP, 1 µCi [γ-32P]ATP, 5 mM MgCl2, plus 50 µg/mL horse IgG as carrier protein. The reaction is incubated for 10 min at room temperature, quenched in 140 of 1 M K2PO4, 30 mM EDTA, pH 8.0, captured onto a 96-well polyvinylidene difluoride filter plate, and washed five times with 1 M K2PO4. The filter is allowed to dry completely, and the bound radioactivity is quantitated. IC87114 dilutions are assayed in a final concentration of 1% (w/w) DMSO.

Cell Research:


  • Cell lines: Human bone marrow mononuclear cells (BMMCs) and CD34+ cells
  • Concentrations: 0–100 μM
  • Incubation Time: 48 hours
  • Method:

    For AML cell proliferation assay, BMMCs are isolated and cultured in α-medium with 5% fetal calf serum (FCS) with or without FLT-3 ligand (10 ng/mL) for 48 hours and with or without IC87114. [3H]-thymidine (1 μCi [37 kBq]) is added for a final 6 hours and the amount of radioactivity incorporated is determined by trichloracetic acid precipitation. CD34+ cells from cord blood are cultured in stem cell factor (SCF; 20 ng/mL), FLT-3 ligand (10 ng/mL), and Tpo (20 nM) for 48 hours with or without 10 μM IC87114 and pulsed for 12 hours with [3H]-thymidine.

Animal Research:


  • Animal Models: Wild-type or PI3Kδ mutant (p110δD910A) mice (C57BL/6 or BALB/c)
  • Dosages: 15 mg/kg–60 mg/kg
  • Administration: Oral gavage
