Guvacine hydrochloride is an alkaloid from the nut of Areca catechu, acts as an inhibitor of GABA transporter, and dispalys modest selectivity for cloned GABA transporters with IC50s of 14 μM (human GAT-1), 39 μM (rat GAT-1), 58 μM (rat GAT-2), 119 μM (human GAT-3), 378 μM (rat GAT-3), and 1870 μM (human BGT-3).
Guvacine hydrochloride is a potent inhibitor of GABA transporter, dispalys modest selectivity forcloned GABA transporters with IC50s of 14 μM (human GAT-1), 39 μM (rat GAT-1), 58 μM (rat GAT-2), 119 μM (human GAT-3), 378 μM (rat GAT-3), and 1870 μM (human BGT-3). Guvacine has low affinity at hBGT-1 (IC50 >1 mM)[1]. Guvacine hydrochloride is a potent inhibitor of GABA uptake, but does not inhibit sodium-independent GABA binding, and is weak or inactive as a GABA receptor agonist[2]. Guvacine inhibits the uptake GABA and β-alanine with IC50s of 23 ± 2 μM, 66 ± 11 μM in the Cat spinal cord, and 8 ± 1 μM, 123 ± 28 μM in the rat cerebral cortex, respectively[3].

Cell experiment: | Cells grown in 24-well plates are washed 3 × with Hepes-buffered saline (HBS, in mM: NaC1, 150; Hepes, 20; CaCl2, 1; glucose, 10; KC1, 5; MgCl2, 1; pH 7.4) and allowed to equilibrate on a 37°C slide warmer. After 10 min the medium is removed and unlabeled drugs (Guvacine , etc.) in HBS are added (450 μL/well). Transport is initiated by adding 50 μL per well of a concentrated solution of [3H]GABA in HBS (final concentration = 50 nM). Non-specific uptake is defined in parallel wells with 1 mM unlabeled GABA, and is subtracted from total uptake to yield specific uptake; all data represent specific uptake. Plates are incubated at 37°C for 10 min, then washed rapidly 3 × with ice-cold HBS, using a 24-position plate washer. Cells are solubilized with 0.05% sodium deoxycholate/0.1 N NaOH (0.25 mL/well), an aliquot neutralized with 1 N HC1, and radioactivity is determined by scintillation counting. Protein is quantified in an aliquot of the solubilized cells using a BIO-RAD protein assay kit[1]. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
