Biological Activity

Description Epacadostat (INCB024360) analogue (INCB14943) is a potent, competitive IDO1 (indoleamine-(2,3)-dioxygenase) inhibitor with IC50 of 67 nM.
IDO1 [1]
(Cell-free assay)
67 nM
In vitro

In HeLa cells, INCB024360 shows higher inhibitory activity on IDO1 with IC50 of 19 nM. [1] In coculture systems of human allogeneic lymphocytes with dendritic cells or tumor cells, INCB024360, via IDO1 inhibition, reverses T-cell suppression mediated by IDO-expressing HeLa cells or DCs, and increases the proliferation and functional activity of CD4+ T cells, CD8+ T cells, and NK cells.

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
