N-Methyl-d-aspartate (NMDA) receptors, a subtype of ionotropic glutamate receptors in the central nervous system (CNS), have garnered attention for their role brain disorders. Specifically, GluN2A-containing NMDA emerged as potential therapeutic target treatment depressive disorders and epilepsy. However, development receptor-selective antagonists, represented by N-(4-(2-benzoylhydrazine-1-carbonyl)benzyl)-3-chloro-4-fluorobenzenesulfonamide (TCN-201) its derivatives, faces significant challenge due to limited ability penetrate blood-brain barrier (BBB), hampering vivo characterization further advancement. In this study, we reported series 2-((5-(phemylamino)-1,3,4-thiadiazol-2-yl)thio)-N-(cyclohexylmethyl)acetamide achieved through structure-guided optimization strategy using free energy perturbation (FEP) BBB permeability estimation. Through systematic exploration various phenyl substitutions, compound 1f standout compound, demonstrating substantially enhanced inhibitory activity compared with lead TCN-213. Compound not only displayed satisfactory but also showed antidepressant-like potency hydrocortisone-induced zebrafish depression-like model.

Excitotoxicity is a common pathological process in neurological diseases caused by excess glutamate. The purpose of this study was to evaluate the effect gypenoside XVII (GP-17), monomer, on glutamatergic system. In vitro, rat cortical nerve terminals (synaptosomes), GP-17 dose-dependently decreased glutamate release with an IC50 value 16 μM. removal extracellular Ca2+ or blockade N-and P/Q-type channels and protein kinase A (PKA) abolished inhibitory from synaptosomes. also significantly reduced phosphorylation PKA, SNAP-25, synapsin I vivo model excitotoxicity induced kainic acid (KA), pretreatment prevented seizures rescued neuronal cell injury elevation cortex. expression levels sodium-coupled neutral amino transporter 1, synthesis enzyme glutaminase vesicular 1 but increased level metabolism dehydrogenase cortex KA-treated rats. addition, KA-induced alterations N-methyl-D-aspartate receptor subunits GluN2A GluN2B were pretreatment. decrease cerebral blood flow arginase II expression. These results suggest that (i) GP-17, through suppression N- consequent PKA-mediated SNAP-25 phosphorylation, reduces exocytosis synaptosomes; (ii) has neuroprotective rats regulating synaptic flow.

Cognitive impairment is a core feature of schizophrenia, playing pivotal role in the pathogenesis and prognosis this disorder. schizophrenia encompasses wide range domains, including processing speed, episodic memory, working executive function. These deficits persist throughout course illness significantly impact functional outcomes quality life. Therefore, it imperative to identify biological basis cognitive develop effective treatments. The N-methyl-D-aspartate (NMDA) receptors synaptic transmission plasticity has long been recognized, making them potential targets for treatment. This review will focus on emerging pharmacology targeting NMDA receptors, offering strategies prevention treatment schizophrenia.

Introduction: Epilepsy is a chronic brain disease characterized by repeated seizures and caused excessive glutamate receptor activation. Many plants are traditionally used in the treatment of this disease. This study aimed to evaluate bioavailability polyphenolic extract obtained from Origanum majorana L. (OMP) leaves, as well its antiepileptic activity potential mechanism action. Methods: We have developed validated simple, rapid, accurate stability-indicating reversed-phase liquid chromatographic method for simultaneous determination caffeine quercetin rat plasma. The OMP effect was evaluated with pilocarpine-induced seizures, docking determine possible interaction between caffeic acid N-methyl-D-aspartate (NMDA) receptor. Results Discussion: Both compounds tested showed low unchanged form. However, an anticonvulsant due considerably delayed onset pilocarpine model at dose 100 mg/kg. molecular proved high-affinity NMDA Taken together, OLP polyphenols demonstrated good activity, probably quercetin, acid, or their metabolites
