ido in 6

IDO-IN-6 is an indoleamine 2,3-dioxygenase (IDO) inhibitor.

IDO1/TDO-IN-6 (compound 11) is a dual inhibitor targeting IDO1 and TDO, exhibiting IC50 values of 2.25 μM for IDO1 and 2.89 μM for TDO, with Ki values of 1.9 μM for IDO1 and 3.1 μM for TDO, indicating its potential utility in cancer and immunology research [1].

(S)-Indoximod (L-Abrine) exhibits inhibition of rabbit small intestine indoleamine 2, 3-dioxygenase, competitive inhibition of IDO, reduction of Foxp3 protein expression in tumor of C57BL/6 mouse allografted with mouse LLC cells at 200 mg/kg, induction of IDO1 protein expression in tumor of C57BL/6 mouse allografted with mouse LLC cells at 200 mg/kg, antitumor activity against mouse LLC cells allografted in C57BL/6 mouse, antiproliferative activity against mouse LLC cells at 50 uM.

IDO antagonist-1 (compound 163), an IDO antagonist, effectively inhibits the growth of pancreatic adenocarcinoma cells in C57BL/6 mice [1].
