In the present investigation, a series of 3,6-disubstituted-1,2,4-triazolo-1,3,4-thiadiazole derivatives (6a-t) were synthesized and evaluated for their anticonvulsant activity and neurotoxicity. The structures of synthesized compounds were confirmed on the basis of their elemental analysis and spectral data results. In anti-MES activity compounds 6b, 6c, 6g, 6j, 6k, 6q and 6r showed potent activity comparable to that of standard drugs: phenytoin and carbamazepine. Compounds 6c, 6k, 6n, 6p and 6s successfully passed the rotorod test without any sign of neurological deficit.

variants in children with neurodevelopmental impairment are difficult to assess due to their heterogeneity and unclear pathogenic mechanisms. We describe a child with neonatal-onset epilepsy, developmental impairment of intermediate severity, and G256W heterozygosity. Analyzing prior KCNQ2 channel cryoelectron microscopy models revealed G256 as a node of an arch-shaped non-covalent bond network linking S5, the pore turret, and the ion path.

Epilepsy (EP) is a neurological disorder characterized by abnormal, sudden neuronal discharges. Seizures increase extracellular glutamate levels, causing excitotoxic damage. Glutamate transporter type 1 (GLT-1) and its human homologue excitatory amino acid transporter-2 (EAAT2) clear 95% of extracellular glutamate.

Background: Epilepsy has a genetic predisposition, yet causal factors and the dynamics of the immune environment in epilepsy are not fully understood.
Methods: We analyzed peripheral blood samples from epilepsy patients, identifying key genes associated with epilepsy risk through Mendelian randomization, using eQTLGen and genome-wide association studies. The peripheral immune environment's composition in epilepsy was explored using CIBERSORT.

Rett syndrome (RS) is a rare neurodevelopmental disorder primarily caused by mutations in the X-linked methyl-CpG binding protein 2 (MECP2) gene, responsible for encoding MECP2 which plays a pivotal role in regulating gene expression. The neurological and non-neurological manifestations of RS vary widely in severity depending on the specific mutation type. Bone complications, mostly scoliosis but also osteoporosis, hip displacement, and a high rate of fractures, are among the most prevalent non-neurological comorbidities observed in girls with RS.

This study aimed to design new hybrid compounds with imidazolidin-2,4-dione and morpholine rings as broad spectrum anticonvulsants. To achieve this goal, all compounds were evaluated in animal seizure models, namely the maximal electroshock (MES), the subcutaneous pentylenetetrazole (scPTZ), and selected in the 6 Hz (32 mA) tests. The most promising compound, 5-isopropyl-3-(morpholinomethyl)-5-phenylimidazolidine-2,4-dione (19), demonstrated broader anticonvulsant activity than phenytoin or levetiracetam, with ED50 of 26.
