SB-200646A (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].
