Application: |
PIK-294 has been used as PI3K inhibitor in drug combination studies and their synergy quantification using the Chou-Talalay method. |
Biochem/physiol Actions: |
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. For example, in a study of CXCL8-induced neutrophil migration, PIK-294 inhibited both chemokinetic and chemotactic CXCL8-induced migration whereas PI3Kγ inhibitor AS-605240 markedly reduced CXCL8 induced chemokinetic migration but had no effect on CXCL8 induced chemotactic migration. |
