Summary
680C91 is an orally active, selective tryptophan 2,3-dioxygenase ( TDO ) inhibitor with a K i of 51 nM. TDO is the key enzyme of tryptophan catabolism. 680C91 can be used for the research of cancer immunotherapy and Alzheimer’s Disease [1] [2] [3] [4] .
In Vitro
680C91 is a potent (K
i
=51 nM) and selective TDO inhibitor with no inhibitory activity against indoleamine 2,3-dioxygenase, monoamine oxidase A and B, 5-HT uptake and 5-HT1A,1D,2A and 2C receptors at a concentration of 10 μM
[2]
.
680C91 inhibits the catabolism of tryptophan by rat liver cells and rat liver perfused in situ
[2]
.
Tdo2 could regulate cell proliferation and stimulate the expression of decidual marker Dtprp in the uterine stromal cells and decidual cells. Tdo2 inhibitor 680C91 also inhibits the prolifer ation activity of uterine decidual cells at 24 h
[3]
.
Treatment of leiomyoma smooth muscle cell (LSMC) and myometrial smooth muscle cell (MSMC) spheroids with 680C91 (25 and 50 μM) significantly represses the expression of collagen type I (COL1A1) and type III (COL3A1) in a dose-dependent manner

Cell Proliferation Assay [3]
| Cell Line: | Uterine stromal cells |
| Concentration: | 0.01, 0.05, 0.1, 0.5, 1, 5, and 10 μM |
| Incubation Time: | 24 hours |
| Result: | The proliferation activity of stromal cells was significantly decreased at 5 and 10 μM. |
Western Blot Analysis [4]
| Cell Line: | MSMC and LSMC |
| Concentration: | 25 and 50 μM |
| Incubation Time: | 48 hours |
| Result: | Significantly reduced the expression of COL1A1 and COL3A1 in LSMC spheroids with no significant effect on expression of these proteins in MSMC spheroids. |
In Vivo
680C91 (a dose of 15 mg/kg for acute treatment ) elevates tryptophan in brain [5] .
