(+)-α-Dihydrotetrabenazine is a potent inhibitor of vascular monoamine transporter 2 (VMAT2) and an agent of significant interest for therapeutic and molecular imaging applications.

Definition

ChEBI: (2R,3R,11bR)-9,10-dimethoxy-3-(2-methylpropyl)-2,3,4,6,7,11b-hexahydro-1H-benzo[a]quinolizin-2-ol is a member of isoquinolines.

in vivo

NBI-98782 (10 mg/kg, p.o., daily for 7 days) decreases basal and APDs-induced monoamine efflux in both mPFC and dSTR in male C57BL/6J mice[1].

Animal Model:Male C57BL/6J mice[1]
Dosage:10 mg/kg
Administration:p.o., daily for 7 days
Result:Decreased the efflux of DA, 5-HT and NE in mPFC, dSTR, HIP and NAC.
Increased the efflux of DOPAC, HVA, and 5-HIAA in mPFC, dSTR, HIP and NAC.
Decreased in cortical DA and DOPAC as well as striatal DA, 5-HT and NE efflux combinated with haloperidol (HY-14538, 0.5 mg/kg, i.p.).
Decreased cortical Glu and striatal ACh, DA and GABA efflux combinated with Clozapine (HY-14539, 10 mg/kg, i.p.).
Reduced PCP-induced increase in LMA between various time points.
Suppressed clozapine-, olanzapine- and risperidone-induced DA efflux in both mPFC and dSTR, and ACh efflux in mPFC.
