rgat-2

(S)-SNAP5114 是一种选择性的 GABA 转运抑制剂，对 hGAT-3 的 IC50 为 5 μM，对 rGAT-2 的 IC50 为 21 μM。 (S)-SNAP5114 具有抗惊厥性质。

SKF89976A is a potent GABA uptake inhibitor, which is selective for GAT-1 (IC50 values are 0.13, 550, 944 and 7210 μM for hGAT-1, rGAT-2, hGAT-3 and hBGT-1 respectively). SKF89976A inhibits transport current competitively (Ki = 7 μM) and transmitter-gated current non-competitively (Ki = 0.03 nM). It is able to pass the blood-brain barrier after systemic administration and is active in vivo.
