Bioactivity Comments
Velusetrag is 3300-fold selective for 5-HT4C compared to the 5-HT3 receptor [6]. Smith et al. (2008) provide radioligand binding affinity data for velusetrag across a large range of receptors and enzymes [9]. The pKi in the table below was generated using the 5-HT4C splice variant of the human receptor.
