Product Information
Description: (+)-Tetrabenazine ((+)-TBZ; (3R,11bR)-TBZ; (3R,11bR)-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-2 In 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]
   
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
