1-METHYL-D-TRYPTOPHAN Chemical Properties,Usage,Production

Description

Indoleamine 2,3-dioxygenase (IDO) metabolizes tryptophan to kynurenine, leading to the production of NAD⁺ via the kynurenine pathway. The overexpression of IDO in tumors and tumor-draining lymph nodes induces immune tolerance and enhances tumor growth in vivo. 1-methyl-D-Tryptophan is an inhibitor of IDO (IC₅₀ = 7 μM) that is effective in vivo. In mice, 1-methyl-D-tryptophan prevents T-cell anergy triggered by dendritic cells overexpressing IDO. It augments the antitumor and antiviral immunoresponse of CD8⁺ T-cells and reduces tumor volume in mice with xenografts overexpressing IDO. 1-methyl-D-Tryptophan, in combination with chemotherapy, causes regression of tumors and prolongs survival. Surprisingly, 1-methyl-D-tryptophan induces the expression of IDO in human ovarian carcinoma SKOV3 cells in culture.

Uses

1-Methyl-D-tryptophan is used in biological studies to determine the effect of IDO2 enzyme (indoleamine-(2,3)-dioxygenase) activity and IDO2-mediated arrest of human T cell proliferation. It reverses IDO-mediated immune suppression
