      Brivaracetam(UCB-34714) is a 4-substituted pyrrolidone butanamide as agent with significant antiepileptic activity; high affinity SV2A ligand and also shows an ability to inhibit Na+ channels.;IC50 value:;Target: SV2A ligand;In vitro: Brivaracetam has been tested in a comprehensive safety pharmacology, toxicology, developmental toxicology, and genotoxicity program. It is of low acute toxicity, target organ for toxic effects is the hepatobiliary tract. Carcinogenicity studies are ongoing. Human pharmacology studies have shown that brivaracetam has a half-life of 8 h and nearly complete bioavailability [1]. CSD episodes were regularly elicited on slices upon delivery of calibrated KCl drops and were recorded via two micropipette electrodes. After control CSDs, the drug was added to the perfusion and five subsequent CSDs were elicited during drug perfusion. Effects were assessed via CSD amplitude (Ampl) and duration at half-amplitude (D(1/2)). BRV, 10 and 32 microM reduced the Ampl an MedChem Express HY-14449
