IDO5L is a potent inhibitor of IDO with an IC50 value of 19 nM in Hela cells[1].
体内研究
Evaluation of IDO5L in mice illustrates pharmacodynamic inhibition of IDO, as evidenced by decreased kynurenine levels (>50%) in plasma and dose-dependent efficacy in mice bearing GM-CSF-secreting B16 melanoma tumors. Initial oral pharmacokinetic studies reveal rapid clearance of IDO5L (t1/2<0.5 h), rendering oral administration unsuitable for in vivo studies. Plasma exposure measurements (2.5 μM) of IDO5L during this period surpass the calculated mouse protein binding-adjusted B16 cellular IC50 (PBadjIC50=1.0 μM, murine cellular B16 IC50=46 nM). Notably, kynurenine levels return to baseline after 4 hours as IDO5L exposure levels drop below the mouse PBadjIC50 from 1.0 to 0.1 μM[1].
