Used in research settings for studying sigma receptors, particularly the sigma-1 receptor, due to its high binding affinity. It serves as a pharmacological tool to investigate receptor function in cellular models and neurological pathways. Has been explored for potential anti-cancer properties in preclinical studies, showing activity in inhibiting tumor cell proliferation, including in prostate and breast cancer cells potentially via sterol synthesis regulation. Also utilized in neuroscience to examine roles in neuroprotection, pain modulation, immune response regulation, and psychiatric behaviors such as depression and paranoia. Not used clinically and remains primarily a research compound.
