SB200646A (4 μM) abolishes the ethanol-induced increase in miniature inhibitory postsynaptic current (mIPSC) frequency and had no effect on basal mIPSC frequency[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
The i.v. administration of 4-16 mg/kg of SB-200646A significantly increases the firing rate and % events as bursts in spontaneously active VTA dopaminergic neurons and significantly increases the % events as burst in substantia nigra pars compacta (SNC) dopaminergic neurons[1].

Animal Model:Male albino Sprague-Dawley rats (200-225 g at the beginning of treatment and 300-350 g at the time of the experiment)[1]
-
Dosage:20 mg/kg
-
Administration:Intravenous injection; daily; for 21 days
-
Result:Significantly decreased the number of spontaneously active ventral tegmental area (VTA) dopaminergic neurons.
