Mechanism of Action

Targets/IC₅₀/Ki	IDO1 (Cell-free assay) 38 nM
In vitro	IDO-IN-2 (NLG-919 analogue, Compound 24) contains an imidazoleisoindole core and exhibits potent inhibitory activity to IDO1 with the IC50 value of 38 nM. This compound inhibits IDO activity with EC50 of 61 nM in HeLa cellular assay. The binding mode of this chemical to IDO1 is experimentally available and shows a direct coordinative interaction to the sixth coordination site of ferric heme. It has been used as reference compound in other studies to validate high-throughput screening assay for IDO1 inhibition and develop immunostimulatory nanomicellar carrier.
