Therapeutic modulators of the serotonin 5-HT4 receptor: a patent review (2014-present).

The therapeutic potential of 5-HT4R modulators has been explored for several years in animal models, but also linked to potential safety issues with initial ligands. The current use of prucalopride in humans demonstrates that its toxicity is not linked to the target and that 5-HT4R modulators are safe in humans. Therefore, an important number of studies and patents has continued in the recent years to expand the use of 5-HT4R modulators, not only to treat gastrointestinal disorders, but also for CNS pathologies. This article details current efforts in this development.
