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.

SKF89976A is a selective GABA transporter (GAT-1) inhibitor with IC50s of 0.28 μM, 137.34 μM and 202.8 μM for GAT-1, GAT-2 and GAT-3 in CHO cells, respectively.

ChEBI: 1-(4,4-diphenylbut-3-enyl)-3-piperidinecarboxylic acid is a diarylmethane.
