Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O	3.15mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 63 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	0.39mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 7.8 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.

生物活性

製品説明	PIK-III (VPS34-IN2), which is a selective inhibitor of VPS34 enzymatic activity, inhibits autophagy and de novo lipidation of LC3 and leads to the stabilization of autophagy substrates.
in vitro	VPS34 enzymatic function is essential for LC3 lipidation in mammalian cells and PIK-III is a robust inhibitor of autophagy and LC3 lipidation in mammalian cells. In H4 cells, PIK-III inhibits the formation of autolysosomes and increases the cytosolic signal of LC3 under basal conditions and when autophagy is induced with the mTOR inhibitor AZD8055. In a CCCP-induced mitophagy model, PIK-III inhibits the clearance of mitochondria.PIK-III treatment leads to an increase in the levels of LC3-I in H4 and PSN1 cells. In Panc10.05 cells, PIK-III increases the levels of LC3-II in parallel with LC3-I suggesting a cell type-specific response^[1].

細胞アッセイ	細胞株	H4 cells/ HeLa cells
	濃度	2.5μM in H4 cells/5μM in Hela cells
	反応時間	overnight for H4 cells/12h for Hela cells
	実験の流れ	To determine whether inhibition of VPS34 function impacts autophagy，LC3 and known autophagy substrates such as damaged mitochondria or the autophagy cargo receptor p62 are monitored. H4 cells expressing mCherry–GFP–LC3 are treated overnight with the indicated compounds, fixed, stained with Hoechst 33342 and imaged by automated acquisition. HeLa cells expressing GFP–Parkin are treated with PIK-III for 12 h followed by the addition of CCCP for 12 h, fixed, stained for endogenous Tom20 and imaged.
