Siramesine has been studied primarily for its potential therapeutic applications in the field of neuroscience, particularly in the treatment of psychiatric disorders. It acts as a sigma-2 receptor ligand, which is believed to play a role in modulating anxiety and depression. Research has explored its anxiolytic and antidepressant properties, suggesting it could offer an alternative to traditional treatments with fewer side effects. Additionally, siramesine has been investigated for its potential in cancer therapy, as sigma-2 receptors are often overexpressed in tumor cells. By targeting these receptors, it may induce apoptosis in cancer cells, making it a candidate for further development in oncology. Its dual role in both mental health and cancer research highlights its versatility in medical applications.
