L-TBOA ammonia salt

Description

Very potent blocker for the human excitatory amino acid transporters (EAAT1–3; IC50 values 23 µM, 3.8 µM, 7.0 µM for EAAT1, EAAT2, and EAAT3, respectively). L-TBOA is the most active isomer of DL-TBOA, as sold by competitors, and approximately twice as potent for inhibition of EAAT1 and EAAT2.
