Biological Activity

Description Carbamazepine (Carbatrol, NSC 169864) is a sodium channel blocker with IC50 of 131 μM in rat brain synaptosomes.
Features Frequently prescribed first-line drug for the treatment of partial and generalized tonic-clonic epileptic seizures.
Targets
Sodium channel [1]
131 μM
In vitro
In vitro Carbamazepine inhibits the binding of [3H]batrachotoxinin A 20-α-benzoate (BTX-B) to a receptor site of voltage-sensitive sodium channel with IC50 of 131 μM, to decrease the activation of sodium channel ion flux in rat brain synaptosomes. Carbamazepine reduces receptor affinity due to an increased rate of ligand dissociation from the receptor-ligand complex, without altering maximal binding capacity from the scatchard analysis of BTX-B binding to synaptosome, suggesting an indirect allosteric mechanism for anticonvulsant inhibition of BTX-B binding. Carbamazepine does not alter basal 125I-labeled scorpion toxin binding to synaptosomes in the absence of batrachotoxin, but when batrachotoxin (1.25 μM) added, Carbamazepine inhibits the batrachotoxin-dependent increase in scorpion toxin binding in a concentration-dependent manner with IC50 of 260 μM mediated at the alkaloid toxin binding site, none of which affects [3H]saxitoxin binding.

In Vivo
In vivo Carbamazepine at 25 mg/kg significantly increases extracellular levels of striatal and hippocampal dopamine (DA), 3,4-dihydroxyphenylalanine (DOPA), 3,4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) in a dose dependent manner, while Carbamazepine at 50 mg/kg significantly decreases total levels of striatal DA and DOPA as well as hippocampal HVA, but has no effect on total levels of striatal DOPAC and HVA nor on hippocampal DA, DOPA and DOPAC. [2] Intraperitoneal administration of Carbamazepine （~100 mg/kg）to rats produces significant increases in the cerebral cortical concentrations of neuroactive steroids and neuroactive steroids in plasma in a dose and time dependent maner with DHEA formed as a result of side chain cleavage of pregnenolone not affected.

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.
