PDE12-IN-1 is primarily used in biochemical research to study the function and inhibition of phosphodiesterase 12 (PDE12), an enzyme involved in RNA metabolism. It serves as a tool compound to investigate the role of PDE12 in cellular processes, particularly in the regulation of cyclic nucleotide signaling pathways. Researchers utilize PDE12-IN-1 to explore its potential therapeutic applications in diseases where PDE12 activity is implicated, such as neurodegenerative disorders and viral infections. Its application in laboratory settings helps in understanding the enzyme's mechanism and developing targeted inhibitors for drug discovery.
