Biochem/physiol Actions

ORG 25543 is a brain-penetrant (free brain/plasma ratio = 0.53; 35 min post 2 or 20 mg/kg i.v. in mice), high-affinity, potent and selective glycine transporter 2 (GlyT-2; GlyT2) inhibitor (human & mouse pIC50 = 7.9/ GlyT2 vs <4/GlyT1) with great selectivity over a panel of 56 receptor and channel proteins. ORG 25543 is more potent and selective than the brain-impermeable ALX-1393 (GlyT2/GlyT1 pIC50 = 7.1/5.4) and exhibits high in vivo efficacy in a murine diabetic neuropathic pain model (ED50 = 0.07-0.16 mg/kg i.v.; Emin = 0.01 mg/kg). ORG 25543 is practically irreversible due to its tight-binding nature, suboptimal dosage should be applied in vivo to allow low target occupancy only and minimize acute toxicity.

Available medications for chronic pain provide only partial relief and often cause unacceptable side effects. There is therefore a need for novel molecular targets to develop new therapeutics with improved efficacy and tolerability. Despite encouraging efficacy data in rodents with

Neuropathic pain is refractory against conventional analgesics, and thus novel medicaments are desired for the treatment. Glycinergic neurons are localized in specific brain regions, including the spinal cord, where they play an important role in the regulation of pain signal

Spinal parvalbumin-expressing interneurons have been identified as a critical source of inhibition to regulate sensory thresholds by gating mechanical inputs in the dorsal horn. This study assessed the inhibitory regulation of the parvalbumin-expressing interneurons, showing that synaptic and tonic glycinergic

There is increasing evidence for the neuronal coexistence of classical transmitters. Implications in favor of cotransmission have often been represented by the identification, in the same neuron, of the putative cotransmitters, their synthetic enzymes and/or their vesicular transporters. In contrast

Glycine release provoked by ion dysregulations typical of some neuropathological conditions was analyzed in cerebellar synaptosomes selectively pre-labelled with [³H]glycine through GlyT2 transporters and exposed in superfusion to KCl, 4-aminopyridine (4-AP) or veratridine. The overflows caused by relatively low concentrations
