生物活性

Indoximod (1-Methyl-D-tryptophan) is an orally active indoleamine 2,3-dioxygenase (IDO) pathway inhibitor. Indoximod acts as a Trp mimetic in regulating mTOR. Indoximod is an immunometabolic adjuvant used for the research of cancer[1][2].

IC50 & Target[1]

IDO

19 μM (Ki)

体外研究
(In Vitro)

The IDO inhibitor 1-methyl-tryptophan exists in two stereoisomers with potentially different biological properties. The L isomer is the more potent inhibitor of IDO activity using the purified enzyme and in HeLa cell–based assays. However, the D isomer is significantly more effective in reversing the suppression of T cells created by IDO-expressing dendritic cells. The L isomer of 1-methyl-tryptophan functioned as a competitive inhibitor (Ki=19 μM), whereas the d isomer is much less effective. The DL mixture is intermediate, with a Ki of 35 μM[1].

体内研究
(In Vivo)

The D isomer is more efficacious as an anticancer agent in chemo-immunotherapy regimens using NSC-26271, NSC 125973, or LY 188011, when tested in mouse models of transplantable melanoma and transplantable and autochthonous breast cancer. The D isomer of 1-methyl-tryptophan specifically targets the IDO gene because the antitumor effect of d-1-methyl-tryptophan is completely lost in mice with a disruption of the IDO gene (IDO-knockout mice). Oral administration of dl-1-methyl-tryptophan in combination with NSC 125973 can elicit regression of autochthonous breast tumors[1].

[1]

1MT enantiomers are solubilized in DMSO containing 0.1N HCl and added at concentrations of 100, 50, and 0 µM to wells containing the reaction mixture with tryptophan (0-200 µM) followed by addition of IDO enzyme. Plates are sealed and incubated 1 hr in a humidified 37°C incubator, after which the reactions are terminated by addition of 12.5 µl 30% TCA per well. Plates are then resealed in plastic wrap, incubated 30 min at 50°C to hydrolyze the reaction product N-formylkynurenine to kynurenine, and centrifuged. Supernatants are transferred to a flat-bottom 96-well plate, mixed with 100 µl Ehrlich reagent and incubated 10 min at room temperature. Absorbance at 490 nm is read[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
