GtoPdb Ligand ID: 9376

Synonyms: IC87114
PDB Ligand Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: IC-87114 is a selective inhibitor of PI3Kδ [1-2].
Given that PI3Kδ is preferentially expressed in cells of hemopoietic lineage and is involved in neutrophil chemotaxis we have tagged this ligand as having immunopharmacology relevance. Using this chemical tool in in vitro chemotaxis experiments reveals that PI3Kδ activity is required for the directional component of chemotaxis, but is not required for random movement [2].

Bioactivity Comments
IC-87114 is 58-fold more selective for PI3Kδ compared to PI3Kγ, and >100-fold selective over PI3Kα and PI3Kβ [2]. With respect to protein kinases, 100 μM IC-87114 did not significantly inhibit p38 MAPK, CHK1, DNA-PK, or cSrc.
