INCB024360 analog (Epacadostat analog; INCB-024360 analog; IDO-IN-2), a hydroxyamidine-based compound, is an orally bioavailable and competitive inhibitor of IDO1 (indoleamine-(2,3)-dioxygenase) with potential immunomodulating and anticancer activities. It inhibits IDO1 with an IC50 of 67 nM. INCB024360 analog demonstrates high anti-proliferative activity in vitro and in vivo antitumor efficacy as well.
ln Vitro |
IDO5L, or compound 5l, is a strong IDO inhibitor (HeLa IC50=19 nM)[1]. In the HeLa cell test, IDO5L is one of the most powerful inhibitors of IDO1 (IC50=19 nM)[2].

ln Vivo |
When mice with GM-CSF-secreting B16 melanoma tumors are tested for IDO5L, the results show pharmacodynamic inhibition of IDO as indicated by decreased plasma levels of kynurenine (>50%) and dose-dependent efficacy. IDO5L is rapidly cleared (t1/2<0.5 h), according to preliminary oral pharmacokinetic studies, and oral administration is not a suitable dosing method for in vivo studies. During this period, the measured plasma exposure of IDO5L (2.5 μM) was higher than our calculated B16 cellular IC50 for mouse protein binding adjusted (PBadjIC50 = 1.0 μM, murine cellular B16 IC50 = 46 nM). Notably, after 4 hours, kynurenine levels returned to baseline as IDO5L exposure levels dropped from 1.0 to 0.1 μM below the mouse PBadjIC50[1].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (9.20 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (9.20 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 2.5 mg/mL (9.20 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. Solubility in Formulation 4: 2% DMSO+corn oil: 5mg/mL |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution 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 stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
