Trans-4-aminocrotonic acid (TACA), a potent agonist of GABA(A) and GABA(C) receptors, shows a proconvulsant action in the electroconvulsive threshold test in mice.
Journal Title: Pharmacological Reports - Year 2005, Vol 57, Issue 1
Abstract
In the present study, we evaluated TACA (a potent agonist of GABA(A) and GABA(C) receptors) in the electroconvulsive threshold test in mice. Surprisingly, TACA (at 15 and 25 mg/kg) significantly decreased the threshold. The highest ineffective dose of TACA was estimated as 10 mg/kg. The obtained results indicate that the drug enhancing GABAergic transmission may possess proconvulsant properties in the electroconvulsive test. Such effect was completely opposite to our primary assumption and expectance.
