Biological Activity

Description Sertraline HCl (CP-51974-1) is a 5-HT antagonist with Ki of 13 nM.
5-HT [1]
13 nM(Ki)
In vitro

Sertraline exhibits better selectivity for inhibiting 5-HT uptake relative to NE uptake than fluvoxamine, zimelidine, norzimelidine, fluoxetine or chlorimipramine. However, Sertraline is less selective for blocking 5-HT uptake, relative to DA uptake than these agents. [1]

In vivo Sertraline HCl (32μmol/kg i.p.) inhibits serotonin uptake into striatal synaptosomes from rats by more than 50%. Sertraline HCl is 6 times more potent than chlorimipramine and 60 times more potent than amitriptyline in reversing the 5-HT depletion elicited by PCA. Acute and repeated dosing of sertraline decreased serotonin content of whole blood. Sertraline HCl strongly reduces immobility of mice in the Porsolt swim test for antidepressants. After repeated dosing in rats, sertraline HCl diminishes the cyclic AMP response of limbic forebrain adenylate cyclase to norepinephnne, as well as the binding of [3H]dihydroalprenolol to cortical membranes.

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.
