Biological Activity

Description SAR405 is a low-molecular-mass kinase inhibitor of 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.
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].

Protocol

Cell Research:

[1]
+ Expand
  • 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 hydroxychloroquine with Vps34 compound or DMSO. For mTOR inhibitor, GFP-LC3 H1299 cells are treated with 1 μM AZD8055 for 4 h in fed conditions (DMEM, 10% FCS, 1 mM L-glutamine with SAR405 or DMSO. 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.

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
