Eplivanserin
Eplivanserin (SR-46349) is a potent, selective and orally active 5-HT2A receptor antagonist, with an IC50 of 5.8 nM in rat cortical membrane, and a Kd of 1.14 nM. Eplivanserin displays >20-fold selectivity more selective for 5-HT2A than 5-HT2B and 5-HT2C.

Eplivanserin hemifumarate (SR 46349B) shows weak inhibition on other 5-HT kinases, with IC50s of 0.12 μM (Pig cortex 5-HT1C), 14 μM (Rat hippocampus 5-HT1A), and 16 μM (Rat stnatum 5-HT1B, Ox caudate nucleus 5-HT1D). Eplivanserin also has inhibitory effects on rat cortex adrenergic α1 and α2, rat whole brain histammine H1, Na+ channel, and rat striatum dopamine D1 and D2, with IC50s of 3.4 μM, 1.0 μM, 5.0 μM, 39 μM, 9 μM and 28 μM, respectively[1].
