Description of Carabersat

Carabersat is a potent anticonvulsant agent.

[3H]Carabersat ([3H]SB 204269) binds to rat forebrain membranes with moderate affinity (Kd 40 nM) and pKi values of 7.3[1]. Carabersat is able to bind to mouse forebrain membranes, and the binding is saturable and stereospecific, with a Kd of 53 nM. The labelled [3H]Carabersat produces a Kd of 32 nM[2]. Carabersat (SB-204269, 1-100 μM) has no effect on Na+ current in cultured hippocampal neurones. Carabersat also shows no effect on action potential discharges evoked by elevating external K+[3]. Carabersat (SB-204269) is structurally-related to the benzopyran ATP-sensitive potassium channel (KATP) opener, cromakalim, but has opposite stereochemistry, and the mechanism of action of Carabersat is not thought to involve KATP[4].

Carabersat (5b) significantly elevates anticonvulsant activity in mice[1].

Protocol of Carabersat

Animal experiment:

Mice[1]In this model, groups of 10-20 naive mice (25-30 g) are assessed for production of a tonic hindlimb extension seizure following a single corneal electroshock using an "up and down" method of shock titration. The effects of drug treatment are expressed as a percentage change from vehicle control values and statistical comparisons between groups are made. Carabersat is administered orally as a fine suspension in 1% methylcellulose one hour before electroshock application[1].

Working concentration: mg/ml;

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.
3. All of the above co-solvents are available for purchase on the GlpBio website.
