Background:

Relenopride (YKP10811) hydrochloride is a specific and selective 5-HT4 receptor agonist (Ki=4.96 nM). Relenopride hydrochloride has 120-fold and 6-fold lower affinity, respectively, for 5-HT2A (Ki=600 nM) and 5-HT2B receptors (Ki=31 nM) than for 5-HT4. Relenopride hydrochloride increases gastrointestinal (GI) motility[1][2].

Relenopride hydrochloride do not show any significant off-target binding to any other receptors, enzymes, orserotonin-receptor subtypes at 1 μM, except for binding to the 5-HT2A receptor and the 5-HT2B receptor. Relenopride hydrochloride shows antagonist activity at the 5-HT2B receptor with an IC50 of 2.1 μM and no significant activity at the 5-HT2A receptor up to 10 μM. Relenopride hydrochloride shows no activity against serotonin-receptor subtypes 5-HT1B, 5-HT1D, or 5-HT2A at 1 nM to 10 μM, or for serotonin-receptor subtype 5-HT7 at 10 nM to 30 μM[1].
