Description

PIK-294 is a highly selective inihibitor of the phosphoinositide 3-kinase (PI3K) p110δ with an IC50 value of 10 nM compared to IC50 values of 10 μM, 490 nM and 160 nM for PI3Kα/β/γ, respectively. PIK-294 has been used to help distinguish the unique roles of the various PI3-K isoforms. PIK-294 inhibited both chemokinetic and chemotactic CXCL8-induced migration.

How to use

In Vitro:

Analysis of the specific Class I PI3 Kinase catalytic isoforms p110α (IC50=10 μM), p110β (IC50=0.49 μM), p110δ (IC50=0.01 μM) and p110γ (IC50=0.16 μM) using the inhibitor PIK-294 indicates differential roles in CXCL8-induced neutrophil migration. PIK-294 inhibits both chemokinetic and chemotactic CXCL8-induced migration. When cells are pre-treated with the PI3Kδ selective inhibitor PIK-294, CXCL8-induced migration in the non-gradient and the gradient assay is significantly inhibited. PIK-294 is used at two concentrations 1 μM and 10 μM. Pre-treatment with 1 μM inhibits migration to a greater extent in the non-gradient assay than in the gradient assay. Pre-treatment with 10 μM inhibits migration to a significantly greater extent than the lower dose in both assays. Prior to stimulation with CXCL8, pre-treatment of the cells with the PI3K inhibitors, Wortmannin (50 nM), PIK-294 (10 μM) and AS-605240 (10 μM) for 2 minutes, cause a reduction in the phosphorylation of Akt. Pre-treatment of cells prior to stimulation with GM-CSF and the DMSO control with the PI3K inhibitors Wortmannin (50 nM), PIK-294 (10 μM) and AS-605240 (10 μM) for 2 minutes, reduce the phosphorylation of Akt (p<0.05 for inhibition of PI3Kδ).
