iDeg-6
iDeg-6 is a molecular glue degrader that selectively targets IDO1, with a DC50 of 6.5 nM, an IC50 of 16 nM, and a Kd of 1.46 μM. iDeg-6 competes to bind the heme-binding site of apoprotein IDO1, promoting CRL2KLHDC3-mediated polyubiquitination of IDO1 and neddylation-modification-dependent proteasomal degradation. iDeg-6 reduces kynurenine production, abrogates the non-enzymatic pro-tumor migration function of IDO1, and inhibits tumor growth in immunodeficient mice. iDeg-6 can be used in studies of cancer, infection, and neurological diseases (such as melanoma).

iDeg-6 (1-100 nM; 24 h) mediated IDO1 protein depletion in IFN-γ-pretreated, washout wildtype U2OS cells is dependent on KLHDC3, as knockout of KLHDC3 abolishes the degradation and elevates baseline IDO1 levels[1].
