Clear solution
5% DMSO 95% Corn oil
1.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 30 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. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
2.95mg/ml Taking the 1 mL working solution as an example, add 50 μL of 59 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 Duloxetine (LY-248686) is a potent inhibitor of serotonin (5-hydroxytryptamine, 5-HT) and noradrenaline (NE) uptake in vitro and in vivo and is 3- to 5-times more effective at inhibiting 5-HT uptake.
Targets
serotonin reuptake [1] norepinephrine reuptake [1]
In vitro Duloxetine is a potent inhibitor of serotonin (5-HT) and norepinephrine reuptake. Compared with its effects on 5-HT and norepinephrine reuptake, duloxetine weakly inhibits dopamine reuptake and has low binding affinity for other neurotransmitter receptors, including adrenergic, muscarinic (nonselective) and histamine H1 receptors; dopamine D2 receptors; 5-HT1A, 5-HT1D and 5-HT2C receptors; and opioid receptors. In vitro studies showed that more than 90% of duloxetine is protein bound in human plasma. The binding occurs primarily to albumin and a1-acid glycoprotein[1].
In vivo Duloxetine achieves a maximum plasma concentration (Cmax) of approximately 47 ng/mL (40mg twice-daily dosing) to 110 ng/mL (80 mg twice-daily dosing) approximately 6 hours after dosing. The elimination half-life of duloxetine is approximately 10–12 hours and the volume of distribution is approximately 1640 L. The absolute oral bioavailability averaged 50%, ranging from 30% to 80%, after a 60 mg single dose in one study and averaged 43%, ranging from 19% to 71%, in another study. Food and time of day impact duloxetine absorption, with food and bedtime administration delaying tmax by 4 hours[1].
