DAA-1106 is primarily used in scientific research as a selective ligand for the translocator protein (TSPO), previously known as the peripheral benzodiazepine receptor. It is widely utilized in neuroimaging studies, particularly in positron emission tomography (PET) scans, to visualize and quantify TSPO expression in the brain. This application is crucial for studying neuroinflammation, neurodegenerative diseases such as Alzheimer's, and psychiatric disorders. Additionally, DAA-1106 aids in understanding the role of TSPO in cellular processes like mitochondrial function and steroidogenesis. Its high affinity for TSPO makes it a valuable tool for exploring potential therapeutic targets and monitoring disease progression.
