(Rac)-Indoximod (1-Methyl-DL-tryptophan) is an indoleamine 2,3-dioxygenase (IDO) inhibitor. Co-treatment with IFN-γ and (Rac)-Indoximod markedly reduces the activity of human cardiac myofibroblasts (hCMs) expressing α-SMA and induces apoptosis through up-regulating the IRF-1, Fas, and FasL genes[1].

In Vitro	(Rac)-Indoximod (1-Methyl-DL-tryptophan; 0.5 mM; 3 days) inhibits tryptophan depletion, thereby partially reversing the growth-inhibitory activity of IFN-γ, but eventually induces cell death regardless of tryptophan depletion[1]. Cell Viability Assay[1] Cell Line: Human cardiac myofibroblasts (hCMs) Concentration: 0.5 mM Incubation Time: 3 days Result: Growth retardation by IFN-γ was partially reversed on day 2, but cell viability was further reduced on day 3.
