常见问题列表
生物活性
(Rac)-Indoximod (1-Methyl-DL-tryptophan) 是吲哚胺-2,3-双加氧酶 (IDO) 抑制剂。(Rac)-Indoximod 和 IFN-γ 联用显著降低了表达 α-SMA 的人心肌成纤维细胞活性，并通过上调 IRF-1，Fas 和 FasL 基因诱导凋亡(apoptosis)。靶点

体外研究
(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.
Cell Viability Assay
| 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. |
