Biological Activity

[Description]:

Tetrabenazine ((+)-) is a reversible inhibitor of vesicular monoamine transporter 2 (VMAT-2), inhibits transport by VMAT2 with 10-fold greater potency than transport by VMAT1. target: VMAT-2In vitro: Tetrabenazine ((+)-) inhibit the activity of the transporter but appear to interact differently with the protein. [2] Tetrabenazine ((+)-) inhibits reserpine binding to the transporter, suggesting that the sites may interact in an allosteric manner. [1]In vivo: 0.9% saline (80%) and dimethylsulfoxide (DMSO) (20%). Tetrabenazine ((+)-) blocks dopamine (DA) storage and depletes striatal DA; Tetrabenazine ((+)-) was shown to induce tremulous jaw movements (TJMs) in rats and mice. The reference dose for administration is 2.0 mg/kg.[2]
