SB-200646A is the first selective 5-HT2B/2C over 5-HT2A receptor antagonist with pKi values of 7.5, 6.9 and 5.2 for 5-HT2B, 5-HT2C and 5-HT2A, respectively. SB-200646A is orally active and has electrophysiological and anxiolytic properties in vivo[1][2].
In Vitro: SB200646A (4 μM) abolishes the ethanol-induced increase in miniature inhibitory postsynaptic current (mIPSC) frequency and had no effect on basal mIPSC frequency[1].
In Vivo: SB-200646A (20 mg/kg; intravenous injection; daily; for 21 days; male albino Sprague-Dawley rats) treatment significantly decreases the number of spontaneously active ventral tegmental area (VTA) dopaminergic neurons[1].
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].
