The psychotropic potential of coumarins: Mechanisms, efficacy, and future prospects

Mental health disorders, including anxiety, depression, and cognitive impairments, have become increasingly prevalent in modern society, demanding innovative and effective treatment options. While conventional pharmacotherapy remains the cornerstone of psychiatric treatment, its limitations—ranging from side effects to resistance—have fueled the search for novel therapeutic agents. Coumarins, a group of naturally occurring phenolic compounds, have become excellent candidates for this search because they have many biological functions. This review looks at the possibility of coumarins as neuroactive compounds that can change important pathways that could link to mental disorders. Coumarins have powerful antidepressants, anxiety-relieving, and brain-boosting effects because they can change neurotransmitter systems, especially serotoninergic, dopaminergic, and GABAergic pathways. Their anti-inflammatory, antioxidant, and neuroprotective properties also make them potentially useful as medicines, since they can help with the underlying pathophysiology of mental health conditions. Beyond their pharmacodynamic properties, coumarins also present advantages in terms of bioavailability and safety, making them attractive candidates for future drug development. Despite promising preclinical and early clinical findings, the transition from laboratory to therapeutic application remains an unexplored area. Challenges such as dose optimization, formulation strategies, and clinical validation require further exploration. Finally, this review integrates phytochemistry, neuroscience, and psychopharmacology to discuss coumarins, a class of naturally occurring neurotherapeutics with limited research. As more research is done to find out what all coumarins can do, they may change the way psychiatric treatments are done by providing a natural, multi-target approach to mental health in a time when mental distress is on the rise.
