TFB-TBOA

Key Product Details

Product Description

TFB-TBOA is a potent and selective glial glutamate transporter EAAT1 and EAAT2 inhibitor (IC₅₀ values are 17, 22 and 300 nM for EAAT2, EAAT1 and EAAT3, respectively). Exhibits selectivity for EAAT1 and EAAT2 over EAAT4 and EAAT5, and a wide range of neuronal receptors and transporters. In HEK293 cells expressing human EAAT1, 2, and 3, TFB-TBOA exhibited selectivity for hEAAT1 and hEAAT2 over hEAAT3 (respective IC₅₀ values are 3.6, 10, and 120 nM), while in tsA201 cells expressing rat EAAT4, [³H]-d-Asp uptake was inhibited with an IC₅₀ of 40 nM. Attenuates glutamate-stimulated intracellular Na⁺ elevation in astrocytes in vitro (IC₅₀ = 43 nM). Induces severe convulsions in vivo.
