product name Indoximod (NLG-8189)
Description: Indoximod, also known as NLG8189, and D-1MT (1-Methyl-D-tryptophan), is an IDO pathway inhibitor, it reverses IDO-mediated immune suppression. Indoximod inhibits the enzyme IDO, which degrades the essential amino acid tryptophan, and may increase or maintain tryptophan levels important to T cell function. Tryptophan depletion is associated with immunosuppression involving T cell arrest and anergy.

In vitro activity: Indoximod significantly reverses the suppression of T cells created by IDO-expressing dendritic cells, using both human monocyte-derived dendritic cells and murine dendritic cells isolated directly from tumor-draining lymph nodes. Indoximod activates a Trp sufficiency signal that stimulates mTOR, and relieves IDO-induced Trp deprivation as well as an autophagic response. Kinase Assay: Cell Assay: The immunosuppressive activity of IDO leads to an increase in the number of T-regulatory cells, as measured by their Foxp3+/CD4+/CD25+ phenotype. Indoximod has also been shown to reduce the number of T-regulatory cells. |
