| | indoleaMine-2,3-dioxygenase inhibitor INCB024360 Usage And Synthesis |
| Description | Epacadostat (INCB024360) is a potent and selective indoleamine 2,3-dioxygenase (IDO1) inhibitor with IC50 of 10 nM and displays high selectivity over other related enzymes such as IDO2 or tryptophan 2,3-dioxygenase (TDO). | | In vitro | In IFN-γ–treated human HeLa cells, INCB024360 potently inhibits kynurenine production. INCB024360 also promotes T and natural killer (NK)-cell growth, increases IFN-gamma production, and reduces conversion to regulatory T (T(reg))-like cells. | | In vivo | INCB024360 (100 mg/kg, p.o.), via IDO1 inhibition, suppresses kyn generation and tumor growth in immunocompetent, but not immunodeficient, mice. In mice bearing CT26 colon carcinoma, INCB024360 (100 mg/kg, p.o.) also inhibits the growth of IDO-expressing tumors by reducing kynurenine. | | Uses | INCB024360 acts as a competitive inhibitor of (IDO1) indoleamine 2,3-dioxygenase showing effect in mouse melanoma models. IC50 = 67 nM | | Biological Activity | incb024360 analogue is a potent and selective inhibitor of ido1 with ic50 value of 67 nm. [1]ido (indoleamine-pyrrole 2, 3-dioxygenase) is an enzyme which is encoded by the ido1 gene. ido is the rate-limiting and first enzyme of tryptophan which is one amino acid of human catabolism through kynurenine pathway. the decrease of l-tryptophan can cause halted growth of t cells as well as microbes. ido belongs to immunomodulatory enzyme. it is produced by some activated macrophages and immunoregulatory cells. ido is overexpressed in a wide range of cancer cells such as lung, prostatic, pancreatic, colorectal cancer. it is indentified to help cancer cells to escape the immune system by reducing the level of l-tryptophan in the microenvironment of cells.[2]in hela cells, incb024360 analogue selectively inhibited the activity of human ido1 with ic50 value of 19 nm. on the other hand, incb024360 analogue demonstrated little inhibition activity against tdo (tryptophan 2, 3-dioxygenase). in murine b16 cells, incb024360 analogue inhibited ido with ic50 value of 46 nm [1].in naive c57bl/6 mice, 100 mg/kg incb024360 analogue injected subcutaneously reduced kynurenine levels by >50% via inhibition of ido activity. in c57bl/6 mice bearing gm-csf- secreting b16 tumors, incb024360 analogue (25, 50, and 75 mg/kg b.i.d.) injected subcutaneously for 14 days dose-dependently inhibited tumor growth [1]. | | storage | Store at -20°C | | references | [1]. yue ew1, douty b, wayland b, et al. discovery of potent competitive inhibitors of indoleamine 2,3-dioxygenase with in vivo pharmacodynamic activity and efficacy in a mouse melanoma model. j med chem. 2009 dec 10;52(23):7364-7.
