Description: Gabapentin is a major inhibitory neurotransmitter that functions by binding to the GABA receptors located in the spinal cord. Gabapentin is also noted to bind to a novel site on voltage-sensitive Ca2+ channels. Additionally, Gabapentin is reported to demonstrate inhibition of dopamine release from caudate nucleus, prevent neuronal cell death, and is antinociceptive. It is structurally similar to GABA and is reported in various research studies to increase GABA concentrations within the brain.

|Biological target:||Gabapentin is a GABA analogue, used to treat seizures and neuropathic pain.|
|In vitro activity:||It’s found that 10 mM gabapentin reduces the growth of HCT116 cells, which have an active branched-chain amino acid transferase but express very low levels of BCAT1, and presumably rely on the mitochondrial BCAT2 enzyme. Gabapentin did not affect transamination of BCAA to branched-chain keto acids (BCKA) in HCT116 cells, nor the reverse formation of BCAA from BCKA, indicating that the branched-chain amino acid transaminase is not inhibited. Moreover, the growth-inhibitory effect of gabapentin could not be rescued by supplementation with BCKA, and this was not due to the lack of uptake of BCKA, indicating that other effects of gabapentin are important. An untargeted LC-MS analysis of gabapentin-treated cells revealed a marked depletion of branched-chain carnitines. These results demonstrate that gabapentin at high concentrations can inhibit cell proliferation without affecting BCAT1 and may affect mitochondrial BCKA catabolism.

|In vivo activity:||The antipruritic activity of gabapentin, an anticonvulsant, was studied in a mouse model of allergic itch. In mice sensitized by an extract of the salivary glands of the mosquito (ESGM), an intradermal injection of ESGM elicited scratching and increased peripheral nerve firing. Oral or intradermal administration of gabapentin at the ESGM injection site inhibited ESGM-induced scratching and peripheral nerve firing. However, gabapentin did not affect histamine-induced scratching. The distributions of immunoreactivity to the voltage-dependent calcium channel α2δ-1 subunit, a site of gabapentin action, and the histamine H1 receptor differed in the mouse dorsal root ganglia. The α2δ-1 subunit was mainly found in neurons that were 15-20 µm in diameter, whereas the H1 receptor was mainly in 20-30 µm neurons. In addition, α2δ-1 subunit immunoreactivity co-localized with that of transient receptor potential vanilloid 1 (TRPV1). These results suggest that gabapentin regulates allergic itch by acting on the calcium channel α2δ-1 subunit in peripheral TRPV1-positive neurons.
