Siramesine fumarate salt is primarily studied for its potential therapeutic applications in the field of neuroscience and mental health. It acts as a sigma-2 receptor agonist, which has been explored for its role in modulating anxiety and depression. Research suggests that it may help in reducing symptoms of these conditions by influencing neurotransmitter systems in the brain. Additionally, its interaction with sigma receptors has sparked interest in its potential use for treating neurodegenerative diseases, such as Alzheimer's, by possibly protecting neurons from damage or death. Beyond mental health, siramesine fumarate salt is also investigated for its anti-cancer properties, particularly in inducing apoptosis in cancer cells, making it a candidate for further development in oncology therapies.
