Clear solution
5% DMSO 95% Corn oil
0.3mg/ml Taking the 1 mL working solution as an example, add 50 μL of 6 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.

5%DMSO 40%PEG300 5%Tween80 50%ddH2O
2.4mg/ml Taking the 1 mL working solution as an example, add 50 μL of 48 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description 680C91 is a potent and selective inhibitor of TDO with Ki of 51 nM.
Targets
TDO [1]
(Cell-free assay)
51 nM(Ki)
In vitro

68OC91 is a potent (Ki = 51 nM) and selective TDO inhibitor with no inhibitory activity against indoleamine 2,3-dioxygenase (EC 1.13.11.17), monoamine oxidase A and B, 5-HT uptake and 5-HT1A,1D,2A and 2c receptors at a concentration of 10 μM. 68OC91 has no effect on the binding of tryptophan to serum albumin in plasma and inhibited TDO competitively with respect to its substrate tryptophan. 68OC91 inhibits the catabolism of tryptophan by rat liver cells and rat liver perfused in situ.[1]
In vivo

The catabolism of L-[ring-2-14C]-tryptophan and a load dose of tryptophan (100 mg/kg) in vivo are inhibited by prior administration of 68OC91. Administration of 68OC91 alone produces marked increases in brain tryptophan, 5-HT and 5-HIAA. A load dose of tryptophan (100 mg/kg), producing increases in brain tryptophan 4-fold greater than that seen with 68OC91, does not increase brain 5-HT and 5-HIAA to levels greater than those seen with 68OC91 and produces a shorter-lasting increase in these parameters.[1]
