IDO-IN-7 (NLG-919 analogue) is a potent IDO1 inhibitor (IC50=38 nM). The binding mode of IDO-IN-7 to IDO1 is experimentally available and shows a direct coordinative interaction to the sixth coordination site of ferric heme. IDO-IN-7 has been used as reference compound in other studies to validate high-throughput screening assay for IDO1 inhibition and develop immunostimulatory nanomicellar carrier[1].

Protocole
IDO-IN-7 (NLG-919 analogue) and the selected fragments 8, 15, and 18 are tested in cellular assay for their ability to cross cell membrane and inhibit IDO1 catalytic activity. The cell line of murine mastocytoma P1.HTR stably transfected with murine IDO1 (P1.IDO1) is cultured for 16 hrs in the presence of each compound at the concentration of 30 mM. The ability of P1.IDO1 cells to convert LTrp contained in the culture medium at the concentration of 78.4 μM into L-Kyn is then assessed after 16 hrs of incubation[1].
