Disease relevance of Levetiracetam

  • LEV (25, 50, and 100 mg/kg, p.o.) had no effects on afterdischarge induction and slightly decreased afterdischarge duration, whereas it markedly decreased seizure stage and motor seizure duration [1].

High impact information on Levetiracetam

  • RESULTS: More than 40% of subjects in clinical trials of tiagabine (TGB), topiramate (TPM), and levetiracetam (LEV) experienced an increase in seizures while taking a placebo [3].
  • GBP, LTG, TGB, and LEV, at low concentrations, do not significantly change the metabolic activities examined and do not demonstrate toxic actions on astrocytes [4].
  • This study reports the solubilization of the rat synaptic vesicle protein SV2A, the brain binding site for the antiepileptic drug levetiracetam (LEV), and its characterization [5].
  • Competition binding experiments with a variety of LEV analogues indicated that [3H]ucb 30889 labels the same binding site in both crude homogenates and soluble extracts, with still high stereoselectivity [5].

Gene context of Levetiracetam

  • N-dodecyl-beta-D-maltoside (DDM) was the best detergent at achieving a high percentage of SV2A solubilization and at maintaining the binding characteristics of a tritiated form of a more potent analogue of LEV, [3H]ucb 30889 ((2S)-2-[4-(3-azidophenyl)-2-oxopyrrolidin-1-yl]butanamide) [5].
