Biological Activity

Description Fluvoxamine maleate (DU-23000, MK-264) is a selective serotonin (5-HT) reuptake inhibitor (SSRI), used in the treatment of obsessive-compulsive disorder.
5-HT [1]
In vitro

Fluvoxamine increases [5-HT]ex levels in rat the prefrontal cortex and thalamus, and also increases [DA]ex levels in the striatum. [1] Fluvoxamine maleate ameliorates tactile allodynia via spinal 5-HT2A/2C receptors, by acting on the receptors or 5-HT neurons. [2]

In vivo Fluvoxamine maleate also exhibits the antinociception in a dose-dependent manner in the paw pressure test in non-ligated mice. Fluvoxamine maleate also induces antinociceptive effect in the acute paw pressure test, and this effect is antagonized by the 5-HT3 receptor antagonist granisetron. [2] Fluvoxamine (10 and 30 mg/kg, i.p.) enhances synaptic efficacy in the hippocampo-mPFC pathway in a dose-dependent manner in the rat hippocampo-medial prefrontal cortex (mPFC). [3] Fluvoxamine (10 and 30 mg/kg, i.p.) suppresses long-term potentiation (LTP) in the hippocampal CA1 field of anesthetized rats. Fluvoxamine (30 mg/kg, i.p.)-induced suppression of LTP is completely reversed by the 5-HT(1A) receptor antagonist NAN-190 (0.5 mg/kg, i.p), but not by the 5-HT(4) receptor antagonist GR 113808 (20 mg/rat, i.c.v.) and the 5-HT(7) receptor antagonist DR 4004 (10 mg/rat, i.c.v.). [4] Fluvoxamine maleate reinforces the response to norepinephrine of isolated rat vas deferens incubated in Krebs-Henseleit solution. Fluvoxamine maleate and Fluoxetine hydrochloride inhibit the contraction induced by potassium ion on the isolated rat uterus preparation with IC50 of 3.99μM and 18.2μM, respectively. [5]

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.
