Vigabatrin-13C-d2 (hydrochloride)

Vigabatrin-13C-d2 is intended for use as an internal standard for the quantification of vigabatrin (Item No. 9000976) by GC- or LC-MS. Vigabatrin is an irreversible GABA transaminase (GABA-T) inhibitor.1 It inhibits rat brain GABA-T when used at a concentration of 0.1 mM. Vigabatrin is selective for rat brain GABA-T over P. fluorescens GABA-T at 10 mM and is 100-fold selective over glutamic acid decarboxylase (GAD). Vigabatrin (1,500 mg/kg) decreases brain GABA-T activity without affecting GAD activity in mice.2 It reduces the incidence of myoclonus in a mouse model of audiogenic seizures.3 Vigabatrin also increases the electroconvulsive threshold in mouse model of maximal electroshock-induced seizures and reduces the number of clonic convulsions induced by pentylenetetrazol (PTZ; Item No. 18682) in mice.4 Formulations containing vigabatrin have been used in the treatment of seizures and infantile spasms.WARNING This product is not for human or veterinary use.
