生物活性
| 製品説明 | Topiramate (MCN 4853, RWJ 17021) is a mutil-targeted inhibitor, including voltage-gated sodium channel and calcium channel, AMPA/kainate receptor and carbonic anhydrase, used to treat epilepsy. |
|---|---|
| in vitro | Topiramate slightly inhibits the persistent fraction of Na+ current in dissociated neurons and reduces the Na+-dependent long-lasting action potential shoulders, which can be evoked in layer V pyramidal neurons after Ca+ and K+ current blockade in neocortical slices. [1] Topiramate at low concentrations (IC50, approximately 0.5 mM) selectively inhibits pharmacologically isolated excitatory synaptic currents mediated by kainate receptors containing the GluR5 subunit in whole-cell voltage-clamp recordings from principal neurons of the rat basolateral amygdala. Topiramate also partially depresses predominantly AMPA-receptor-mediated EPSCs, but with lower efficacy. [2] Topiramate (TPM) suppresses voltage-sensitive Na+ channels and non-N-methyl-D-aspartate (NMDA) receptors and enhances gamma-aminobutyric acid (GABA)-mediated inhibition. [3] Topiramate selectively inhibits postsynaptic responses mediated by GluR5 kainate receptors. [4] |
| in vivo | Topiramate (25-100 mg/kg, i.p.) produces a dose-dependent elevation in the threshold for clonic seizures induced by infusion of ATPA, a selective agonist of GluR5 kainate receptors. [4] Topiramate effectively suppresses acute seizures induced by perinatalhypoxia in a dose-related manner with a calculated ED50 of 2.1 mg/kg, i.p. [5] Topiramate (20 and 40 mg/kg i.p.) inhibits both tonic and absence-like seizures in a dose-dependent manner, whereas Phenytoin (20 mg/kg i.p.) and Zonisamide (40 mg/kg i.p.) inhibits only the tonic seizures. Topiramate inhibits sound-induced seizures in DBA/2 mice (ED50 = 8.6 mg/kg p.o.). [6] |
