Actividad biológica
680C91 is a potent (Ki=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[4].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.08 mg/mL (8.73 mM); Clear solution; Need ultrasonic
This protocol yields a clear solution of 2.08 mg/mL.
