描述 | Vabicaserin HCl can replace the binding of 125I-(2,5-dimethoxy)phenylisopropylamine at the human 5-HT2C receptor site on the CHO cell membrane, with a Ki value of 3 nM, and its selectivity exceeds some serotonergic, noradrenergic and 50 times more dopaminergic receptors. The binding affinity to the human 5-HT2B receptor subtype was determined to be 14 nM using [3H]5HT. Vabicaserin HCl is a potent full agonist (EC50, 8 nM; Emax, 100%) in stimulating 5-HT2C receptor-coupled calcium mobilization. Depending on the receptor expression level in transfected cells, it exhibits 5-HT2A receptor antagonism and 5-HT2B antagonism or partial agonistic activity. Vabicaserin exhibits lower affinity at the 5-HT2C antagonist binding site labeled with [3H]mesulergine (22 nM). Additional binding studies have shown that Vabicaserin has affinity for the 5-HT2B and 5-HT1A receptors with Ki values of 14 nM and 112 nM, respectively [1] . |
