0.4mg/ml Taking the 1 mL working solution as an example, add 50 μL of 8 mg/ml clarified DMSO stock solution to 300 μL of PEG 300, mix evenly to clarify it; then continue to add 650 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description TG100-115 is a PI3Kγ/δ inhibitor with IC50 of 83 nM/235 nM, with little effect on PI3Kα/β. Phase 1/2.
Targets
PI3Kγ [1]
(Cell-free assay)		 PI3Kδ [1]
(Cell-free assay)		 PI3Kβ [1]
(Cell-free assay)		 PI3Kα [1]
(Cell-free assay)
83 nM 235 nM 1.2 μM 1.3 μM
In vitro TG100-115 inhibits PI3Kγ and -δ, with IC50 of 83 and 235 nM, respectively. TG100-115 is not active for PI3Kα and -β, with IC50 of 1.2 and 1.3 mM. In human umbilical vein endothelial cells (HUVECs), TG100-115 (up to 10 μM) has no effects on cell proliferation and VEGF-stimulated ERK phosphorylation. However, TG100-115 (10 μM) interrupts other VEGF signaling pathways, such as those that culminate in VE-cadherin phosphorylation. [1] In HUVECs, TG100-115 (10 μM) inhibits the VEGF-induced increase of total level of VE-cadherin. TG100-115 inhibits VEGF mediated phosphorylation of mTOR and p70S6 kinase, both of which are downstream of PI3K. TG100-115 (125 nM to 10 μM) also inhibits FGF-stimulated phosphorylation of Akt. [2]
In vivo In Miles assay models, TG100-115 (1-5 mg/kg) reduces edema formation and inflammation in rats. In rigorous rodent and porcine models of myocardial ischemia (MI), TG100-115 (0.5-5 mg/kg) provides potent cardioprotection, limits infarct development, and preserves myocardial function. [1] In mice, TG100-115 (5 mg/kg) markedly diminishes vascular permeability (VP) in response to either Sema3A or VEGF, indicating that both factors may depend on PI3Kγ/δ to induce VP. [3] In a mouse asthma model, aerosolized TG100-115 markedly reduces the pulmonary eosinophilia, inhibits interleukin-13 and mucin accumulation. [4]
Features A potent and dual selective PI3Kγ/δ inhibitor.

Protocol (from reference)

Kinase Assay:[1]
  • PI3K assays

    Forty mL of reaction buffer (20 mM Tris/4 mM MgCl2/10 mM NaCl, pH 7.4) containing 50 mM D-myo-phosphatidylinositol 4,5-bisphosphate substrate and the desired PI3K isoform are aliquoted to 96-well plates; kinase concentrations are 250-500 ng/well, such that linear kinetics are achieved over 90 min. TG100-115 is then added as 2.5 mL of a DMSO stock to final concentration range of 100 mM to 1 nM. Reactions are initiated by addition of 10 mL of ATP to a final concentration of 3 mM, and after 90 min, 50 mL of Kinase-Glo reagent added to quantify residual ATP levels; luminosity is measured using an Ultra 384 instrument. Control reactions omitting either TG100-115 or substrate are also performed. IC50 values are derived from experimental data by nonlinear curve fitting using Prism Version 4.
