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.

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

At inhibitory synapses, glycine and GABA are accumulated into synaptic vesicles by the same vesicular transporter VGAT/VIAAT (vesicular GABA transporter/vesicular inhibitory amino acid transporter), enabling a continuum of glycine, GABA, and mixed phenotypes. Many fundamental aspects of the presynaptic contribution

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

Glycine can be substrate for two transporters: GlyT1, largely expressed by astrocytes but also by some non-glycinergic neurons, and GlyT2, most frequently present in glycine-storing nerve endings. In morphological studies, GlyT2 expression had been found to be restricted to caudal
