Biological Activity

Description Paroxetine HCl (BRL-29060A, FG-7051) is an antidepressant drug of the SSRI type.
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]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
