Used primarily in scientific research to study the role of the translocator protein (TSPO), FGIN-1-43 is known for its anxiolytic and neuroprotective effects in preclinical models. It modulates mitochondrial function and promotes neurosteroid synthesis, making it a tool compound for investigating anxiety, neurodegeneration, and brain injury. It has also been explored for its potential to reduce intraocular pressure, suggesting possible relevance in glaucoma research. Due to its ability to cross the blood-brain barrier, it is valuable in central nervous system studies, though it remains strictly for experimental use and is not approved for clinical or therapeutic applications.
