Abstract:
Serotonin type 3 (5-HT3) receptor partial agonists have been targeted as potential new drugs for the symptomatic relief of irritable bowel syndrome (IBS). Multiple diazepinone-based compounds have been discovered, which exhibit nanomolar binding affinity for the h5-HT3A receptor and display a range of intrinsic activities (IA=7-87% of 5-HT Emax) in HEK cells heterologously expressing the h5-HT3A receptor. Favorable physicochemical properties and in vitro ADME profile coupled with oral activity in the murine von Bezold-Jarisch reflex model demonstrates the series has promise for producing low to moderate IA partial agonists suitable for an IBS indication.

One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral...
