5%DMSO 40%PEG300 5%Tween80 50%ddH2O
2.35mg/ml Taking the 1 mL working solution as an example, add 50 μL of 47 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Carbamazepine (Carbatrol, NSC 169864) is a sodium channel blocker with IC50 of 131 μM in rat brain synaptosomes.
Targets
Sodium channel [1]
131 μM
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. [1]
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.

Features Frequently prescribed first-line drug for the treatment of partial and generalized tonic-clonic epileptic seizures.
