GtoPdb Ligand ID: 9609

Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: This is the most potent compound developed via a pharmacophore and docking-based virtual screening campaign aimed at the discovery of small molecule inhibitors of the IL-15/IL-15R interaction [2]. Specifically, the investigators were searching for compounds that inhibit IL-15 binding to the IL-2Rβ subunit which together with the γ subunit, forms the signal transducing component of the IL-15R complex. Although the compound was found to be non-selective for IL-15 over IL-2, as a first in vitro SAR study it provides crucial information on the key binding interactions of IL-15 with its IL-2Rβ binding site, that will be useful for futher compound optimisation.
