Biological Activity

Description Gabapentin is a GABA analogue, used to treat seizures and neuropathic pain.
GABA receptor [1]
In vitro

Gabapentin produces concentration-dependent inhibitions of the K(+)-induced [Ca(2+)](i) increase in fura-2-loaded human neocortical synaptosomes with IC50 of 17 mM and maximal inhibition of 37%. Gabapentin may bind to the Ca(2+) channel alpha 2 delta subunit to selectively attenuate depolarization-induced Ca(2+) influx of presynaptic P/Q-type Ca(2+) channels; this results in decreased glutamate/aspartate release from excitatory amino acid nerve terminals leading to a reduced activation of AMPA heteroreceptors on noradrenergic nerve terminals. [1] Gabapentin produces alterations in the cytosolic and extracellular concentrations of several amino acids, including L-leucine, L-valine and L-phenylalanine, in rat cortical astrocytes and synaptosomes, effects that are postulated to be of pharmacological significance. Gabapentin reduces potassium-evoked calcium influx via voltage-gated calcium channels in a mouse pituitary cell line that constitutively expresses GABAB receptors comprising the functional gb1a–gb2 subunit heterodimer. Gabapentin can increase N-methyl-d-aspartate (NMDA)-evoked currents in GABA-positive rat dorsal horn neurones in the presence of protein kinase C, possibly by increasing the glycine sensitivity of the NMDA receptor complex. Gabapentin produces a delayed allosteric enhancement of an unspecified voltage-activated potassium current in rat dorsal root ganglion neurons. [2]

In vivo Gabapentin dose-dependently (10-100 mg/kg, p.o.) blocks both static and dynamic allodynia in the rats. [3]

Calculation results:

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.
