Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
0.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 10 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 Paroxetine HCl (BRL-29060A, FG-7051) is an antidepressant drug of the SSRI type.
Targets
AChR [1] 5-HT [1]
In vitro Paroxetine apparently exerts their antidepressant activity by increasing the concentration of 5-HT in the extracellular compartment, thereby enhancing serotoninergic neurotransmission. Paroxetine (1-300 μM) results in a concentration-dependent reduction in the firing rate of DRN serotoninergic neurons with IC50 values of 1.4 μM in the ACSF superfusing brain stem slices. [1] Paroxetine is a highly potent inhibitor of desipramine hydroxylation, the inhibition constant (Ki) value of 2.0 mM indicated greater inhibiting potency than fluoxetine or norfluoxetine. [2] Paroxetine is shown to be a potent (Ki = 1.1 nM) and specific inhibitor of [3H]-5-hydroxytryptamine (5-HT) uptake into rat cortical and hypothalamic synaptosomes in vitro. Paroxetine demonstrates weak affinity for muscarinic receptors (Ki = 89 nM) but is at least 15 fold weaker than amitriptyline (Ki = 5.1 nM). [3] Paroxetine inactivates CYP2D6 via the formation of a metabolite intermediate complex. [4]
In vivo Paroxetine produces a dose-related inhibition of [3H]-5-HT uptake (ED50 = 1.9 mg/kg) into rat hypothalamic synaptosomes ex vivo with little effect on [3H]-l-noradrenaline (NA) uptake (ED50 greater than 30 mg/kg). Paroxetine (ED50 1-3 mg/kg PO) prevents the 5-HT depleting effect of p-chloroamphetamine (PCA) in rat brain, demonstrating 5-HT uptake blockade in vivo. [3]
