Description

INCB14943, also known as INCB024360-analog, IDO5L and IDO-IN-2 with CAS#914471-09-3, is a potent and orally available hydroxyamidine and inhibitor of indoleamine 2, 3-dioxygenase (IDO1) with potential immunomodulating and antineoplastic activities. INCB024360-analog is a potent (HeLa IC50=19 nM) competitive inhibitor of IDO. Testing of INCB024360-analog in mice demonstrated pharmacodynamic inhibition of IDO, as measured by decreased kynurenine levels (>50%) in plasma and dose dependent efficacy.

How to use

In Vitro:

IDO5L (Compound 5l) is a potent (HeLa IC50=19 nM) inhibitor of IDO. IDO5L is one of the highest potent inhibitors of the IDO1 (IC50=19 nM, in HeLa cell assay).

In Vivo:

Testing of IDO5L in mice demonstrates pharmacodynamic inhibition of IDO, as measured by decreased kynurenine levels (>50%) in plasma and dose dependent efficacy in mice bearing GM-CSF-secreting B16 melanoma tumors. Initial oral pharmacokinetic studies show that IDO5L is rapidly cleared (t1/2<0.5 h) and that oral administration will not be a suitable dosing method for in vivo studies. The measured plasma exposure (2.5 μM) of IDO5L during this period exceeded our calculated mouse protein binding adjusted B16 cellular IC50 (PBadjIC50=1.0 μM, murine cellular B16 IC50=46 nM). Notably, kynurenine levels increase back to baseline after 4 h as IDO5L exposure levels decreased below the mouse PBadjIC50 from 1.0 to 0.1 μM.
