Biological Activity for Tetrabenazine

Tetrabenazine is an inhibitor of vesicular monoamine transport with a 10-fold selectivity for the VMAT2 transporter over VMAT1 (IC₅₀ values = 0.3 μM and 3.4 μM, respectively). Tetrabenazine blocks D₂ receptors and dopamine uptake (IC₅₀ = 0.12 μM) and inhibits serotonin transport by VMAT2 (IC₅₀ = 300 nM). In an animal model of Huntington's disease, Tetrabenazine prevents the decline in motor control and reduces loss of striatal neurons. Tetrabenazine increases cFos expression in the thalamus and hippocampus, reduces brain connectivity and spontaneous locomotion and also causes behavioral depression.

Depletion of dopamine stores

Name: Sergiy Sylantyev

Species: Human

Cell Line/Tissue: Stem cell - derived neurons

Tetrabenazine (TBZ) was used to deplete dopamine stores in cultured dopamine neurons and thus counteract dopamine-generated allosteric antagonism at NMDA receptors. 20-minute incubation of cell culture in 1 µM tetrabenazine had led to significant amplitude increase of NMDA-receptor – generated series of evoked post-synaptic potentials (see illustration).
