生物活性

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).

IC50 & Target

IC50: 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), 1870 μM (human BGT-3)[1]
體外研究
(In Vitro)

Guvacine hydrochloride is a potent inhibitor of GABA transporter, 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 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 Assay
[1]

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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
