Clear solution
2%DMSO 30%PEG300 2%Tween80 66%ddH2O
4.0mg/ml Taking the 1 mL working solution as an example, add 20 μL of 200 mg/ml clarified DMSO stock solution to 300 μL of PEG300, mix evenly to clarify it; add 20 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 660 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 SAR405 is a low-molecular-mass kinase inhibitor of PIK3C3/Vps34 (KD 1.5 nM) showing high selectivity and not be active up to 10 μM on class I and class II PI3Ks as well as on mTOR. SAR405 prevents autophagy and synergizes with MTOR (mechanistic target of rapamycin) inhibition in tumor cells.
Targets
Vps34 [1]
1.2 nM
In vitro

SAR405 is an inhibitor that was highly specific for Vps34 with regard to protein kinases and other phosphoinositide kinases. SAR405 has an IC50 of 1 nM in the phosphorylation of a PtdIns substrate by human recombinant Vps34 enzyme. This compound shows a binding equilibrium constant KD of 1.52 ± 0.77 nM (± s.d.) and a dissociation rate constant, koff, of 3.03 ± 0.55 10−3/s, corresponding to a residence half-life, t1/2, of 3.8 min. SAR405 does not affect the Akt phosphorylation at concentrations up to 10 μM in the PC3 cell line. SAR405 affects vesicle trafficking from late endosomes to lysosomes. It is also a potent autophagy inhibitor[1].
In vivo

SAR405 is a first-in-class, selective, and ATP-competitive PI3K class III (PIK3C3) isoform Vps34 inhibitor.

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    GFP-LC3 HeLa cells

  • Concentrations

    1 μM

  • Incubation Time

    4 h

  • Method

    GFP-LC3 HeLa cells are starved for 2 h in EBSS plus 10 μM Vps34 compound or DMSO. For mTOR inhibitor, GFP-LC3 H1299 cells are treated with 1 μM AZD8055 for 4 h in fed conditions. Cells are then fixed with 4% PFA, and nuclei are stained using 2 μg/ml Hoechst 33342. Fluorescence is analyzed using an imaging cytometer. Cells are considered positive when there are more than four green spots per cell, with a total of 25 fields acquired. The activity of the product is estimated.
Animal Study:

[2]
  • Animal Models

    Nude mice

  • Dosages

    2 mg/kg

  • Administration

    s.c.
