Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O	0.5mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 10 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.
Clear solution	5% DMSO 1 95% Corn oil	1.0mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 20 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. 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

GSK2636771 is a potent, orally bioavailable and selective inhibitor of PI3Kβ with >900-fold selectivity over PI3Kα/PI3Kγ and >10-fold over PI3Kδ. Sensitive to PTEN null cell lines.

Targets

PI3Kβ ^[1]

In vitro

GSK-2636771 shows selectively inhibitory activity in PTEN null cell lines (human prostate adenocarcinoma PC-3 and breast cancer HCC70) with EC50 of 36 nM and 72 nM, respectively. ^[1] GSK2636771 significantly decreases cell viability in p110β-reliant PTEN-deficient PC3 prostate and BT549 and HCC70 breast cancer cell lines, and leads to a marked decrease of AKT phosphorylation only in the control prostate and breast cancer cell lines. ^[2]

In vivo

GSK-2636771 decreases phosphorylated protein kinase Akt (Ser473) levels in these xenograft models. GSK-2636771 (100 mg/kg) do not increase glucose/insulin levels in mice. ^[1]

Protocol (from reference)

Cell Assay:^{^[2]}	Cell lines p110β-reliant PTEN-deficient PC3 prostate and BT549 and HCC70 breast cancer cell lines. Concentrations ~10 μM Incubation Time 72 hours Method Cells are plated in 96-well microtiter plates at densities ranging from 1,500 to 15,000 cells/well, optimized for untreated control cells to be 80-90% confluent at the endpoint of the experiment. After 24 h, cells are treated with serial dilutions (100pM to 10μM) of GSK2636771. Cell viability is assessed after 72 h of treatment by incubation with CellTiter Blue for 1.5 h. The drug concentration requires for survival of 50% of cells relative to untreated cells (surviving fraction 50, SF50) is determined using GraphPad Prism version 5.0d. Cell lines that fails to achieve the SF50 to a given drug are nominally assigned as the highest concentration screened (i.e. 10μM). At least three independent experiments in triplicate per cell line targeted drug are performed. Association between a mutation and response to a targeted agent is determined using a Fisher’s exact test (GraphPad Prism), and a two-tailed P value <0.05 is considered statistically significant.
