Vigabatrin (γ-Vinyl-GABA)，一种抑制性神经递质 GABA 乙烯基衍生物，是一种具有口服活性且不可逆的 GABA 转氨酶 (GABA transaminase) 抑制剂。 Vigabatrin 是一种抗癫痫剂，通过抑制 GABA transaminase 对 GABA 的分解代谢来增加脑中 GABA 的水平。

Vigabatrin (γ-Vinyl-GABA), an inhibitory neurotransmitter GABA vinyl-derivative, is an orally active and irreversible GABA transaminase inhibitor. Vigabatrin is an antiepileptic agent, which acts by increasing GABA levels in the brain by inhibiting the catabolism of GABA by GABA transaminase.

A significant increase in seizure threshold is observed following systemic (i.p.) administration of high (600 or 1200 mg/kg) doses of Vigabatrin. Bilateral microinjection of Vigabatrin (10 μg) into either the anterior or posterior substantia nigra pars reticulata (SNr) also increased seizure threshold, but less markedly than systemic treatment. Focal delivery into the subthalamic nucleus (STN) increased seizure threshold more markedly than either intranigral or systemic administration of Vigabatrin. has not independently confirmed the accuracy of these methods. They are for reference only.

Vigabatrin inhibits the uptake of taurine in Caco-2 and MDCK cells to 34% and 53%, respectively, at a concentration of 30 mM. In Caco-2 cells the uptake of Vigabatrin under neutral pH conditions is concentration-dependent and saturable with a Km-value of 27 mM. Vigabatrin is able to inhibit the uptake of taurine in intestinal and renal cell culture models. has not independently confirmed the accuracy of these methods. They are for reference only.
