Description：Zacopride is an orally active 5-HT3 receptor (Ki of 0.38 nM) antagonist and 5-HT4 receptor (Ki of 373 nM) agonist. Zacopride exhibits multiple activities, such as regulating gastrointestinal motility, affecting cardiac function, and exerting anxiolytic and antiemetic effects. Zacopride is currently mainly used in the research of gastrointestinal diseases, cardiovascular diseases, and psychiatric diseases such as anxiety.

In Vitro：Zacopride (3-30 μM) reduces the 5-HT-induced maximum contraction response of guinea pig colon in a concentration-dependent mannersup[3]. Zacopride produces 5-HT4 receptor-mediated relaxation of the rat esophagus with an EC50 value of 0.5 μM[3]. Zacopride (10 μM) shortens duration of action potentials in guinea pig isolated papillary muscles[11].

In Vivo：Zacopride (0.1 mg/kg; p.o.; single dose) can induce vomiting in ferrets[4]. Zacopride (0.1 mg/kg; intraperitoneal injection; single dose) can completely block the vomiting induced by oral administration of 0.1 mg/kg Zacopride in ferrets[4]. Zacopride (0.1 mg/kg; intraperitoneal injection; single dose) can significantly attenuate the increase in extracellular dopamine levels in the nucleus accumbens induced by cocaine in rats[5]. Zacopride (Zacopride chlorhydrate, 1.0 mg/kg; intraperitoneal injection; single dose) combined with Tacrine can improve the accuracy of rats at the shortest delay (0-4 s) in a spatial working memory task[6]. Zacopride (0.01-31.6 mg/kg; p.o.; multiple doses until vomiting occurs) induces vomiting in 100% of ferrets at a cumulative dose of 0.11 mg/kg[7]. Zacopride (0.5 mg/kg; intravenous injection; single dose) combined with Etorphine can alleviate the decrease in respiratory rate caused by Etorphine in goats, increase hemoglobin oxygen saturation and arterial oxygen tension, while reducing carbon dioxide tension and improving ventilation[8]. Zacopride (0.1-1.0 mg/kg; intraperitoneal injection; single dose) exhibits anxiolytic effects in mice (social interaction and elevated plus maze test)[9]. Zacopride (0.0001-10 mg/kg; intraperitoneal injection; single dose) can enhance the exploratory behavior (black-white test box test) and social interaction (social interaction test with rats) of mice[10].
