TQS is primarily utilized in neuroscience research as a potent and selective positive allosteric modulator (PAM) of the α7 nicotinic acetylcholine receptor (nAChR). It enhances the receptor's response to acetylcholine, making it a valuable tool for studying the role of α7 nAChRs in cognitive functions, memory, and neuropsychiatric disorders. Researchers use TQS to investigate its potential therapeutic applications in conditions such as Alzheimer's disease, schizophrenia, and attention deficit hyperactivity disorder (ADHD). Additionally, it aids in understanding the receptor's involvement in inflammation and immune responses, providing insights into novel treatment strategies for inflammatory diseases. Its specificity makes it a key compound in drug discovery and development targeting α7 nAChRs.
