Paroxetine HCl (formerly BRL-29060A, BRL29060A, FG7051; FG-7051), the hydrochloride salt of Paroxetine, is a potent and selective serotonin uptake inhibitor (SSRI) that is effective in the treatment of depression. It is commonly prescribed as an antidepressant and has GRK2 inhibitory ability with IC50 of 14 μM .Paroxetine binds to the pre-synaptic serotonin transporter complex resulting in negative allosteric modulation of the complex thereby blocking reuptake of serotonin by the pre-synaptic transporter. Paroxetine HCl has also displayed a high affinity for muscarinic acetylcholine receptors.
| ln Vitro |
By inhibiting GRK2, paroxetine (1 μM and 10 μM) significantly prevents T cell migration induced by CX3CL1. GRK2-induced ERK activation is inhibited by paroxetine [1]. Proinflammatory cytokines are decreased in LPS-stimulated BV2 cells by paroxetine (10 μM). TNF-α and IL-1β production in BV2 cells is dose-dependently inhibited by paroxetine (0-5 μM). Additionally, inducible nitric oxide synthase (iNOS) expression and lipopolysaccharide (LPS)-induced nitric oxide (NO) production are inhibited by paroxetine in BV2 cells. In BV2 cells, paroxetine (5 μM) reduces basal ERK1/2 activity and inhibits JNK activation triggered by LPS. In primary microglia, paroxetine inhibits NO production and LPS-stimulated pro-inflammatory cytokines, thereby reducing microglia-mediated neurotoxicity [4].

| ln Vivo |
Treatment with paroxetine hydrochloride considerably reduced the CIA rats' symptoms. Treatment with paroxetine hydrochloride greatly decreased T cell infiltration into synovial tissue and prevented injury to joint tissue. In synovial tissue, the synthesis of CX3CL1 is strongly inhibited by paroxetine hydrochloride [1]. Rats' distal myocardium's myocyte cross-sectional area and ROS production are decreased by paroxetine hydrochloride (20 mg/kg/day). Ventricular tachycardia susceptibility is decreased by paroxetine hydrochloride. After MI, the administration of paroxetine hydrochloride decreases LV remodeling and arrhythmia susceptibility, maybe through lowering ROS production [2]. Paroxetine hydrochloride (10 mg/kg, ip) caused hyperalgesia on days 7 and 10 (P<0.01) in the CCI group, but on day 14, it decreased pain behavior. Furthermore, in comparison with the group given with the CCI vehicle, paroxetine hydrochloride (10 mg/kg) significantly reduced tactile hypersensitivity [5].

For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
