CAS#: 914471-09-3 (INCB024360-analog)

Description: INCB024360-analog, also known as 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. Note: MedKoo CAT#206461, INCB024360 has CAS#1204669-58-8 (http://www.medkoo.com/products/6778)

Additional Information

INCB024360-Analog is structurally related to Epacadostat (INCB024360). Before middle of 2015, some database (e.g, pubchem CID#11978742) mistakenly listed INCB024360 structure as CAS#914471-09-3, many reagent suppliers included MedKoo used pubchem's structure and sold CAS#914471-09-3 as INCB024360. By middle of 2015, J. Med. Chem (Dounay AB, et al, and Röhrig UF et al ), Sci-Finder and other database (such as ChemIDplus) published the chemical structure of INCB024360, which has CAS#1204669-58-8. Based on the above information, MedKoo decided to re-name Cat#205493, CAS#914471-09-3 as INCB024360-Analog. However, as of August 20, 2015, there are still many reagent companies to sell the wrong INCB024360, which structure was actually CAS#914471-09-3 (or INCB024360-Analog). Customer can email or call MedKoo to clarify the structure issue related to INCB024360. (last updated: 12/21/2015).

Indoleamine 2,3-dioxygenase-1 (IDO1; IDO) mediates oxidative cleavage of tryptophan, an amino acid essential for cell proliferation and survival. IDO1 inhibition is proposed to have therapeutic potential in immunodeficiency-associated abnormalities, including cancer. INCB024360 is a novel IDO1 inhibitor.  In cellular assays, INCB024360 selectively inhibits human IDO1 with IC(50) values of approximately 10nM, demonstrating little activity against other related enzymes such as IDO2 or tryptophan 2,3-dioxygenase (TDO). In coculture systems of human allogeneic lymphocytes with dendritic cells (DCs) or tumor cells, INCB024360 inhibition of IDO1 promotes T and natural killer (NK)-cell growth, increases IFN-gamma production, and reduces conversion to regulatory T (T(reg))-like cells. IDO1 induction triggers DC apoptosis, whereas INCB024360 reverses this and increases the number of CD86(high) DCs, potentially representing a novel mechanism by which IDO1 inhibition activates T cells. Furthermore, IDO1 regulation differs in DCs versus tumor cells. Consistent with its effects in vitro, administration of INCB024360 to tumor-bearing mice significantly inhibits tumor growth in a lymphocyte-dependent manner. Collectively, the data suggest that selective inhibition of IDO1 may represent an attractive cancer therapeutic strategy via up-regulation of cellular immunity.(Blood. 2010 Apr 29;115(17):3520-30. ).
