Used in pharmaceutical research as a key scaffold in the development of kinase inhibitors, particularly for targeting protein kinases involved in inflammatory diseases and cancer. Its structure supports high binding affinity to ATP-binding sites in enzymes, making it valuable in designing selective inhibitors. Also explored in medicinal chemistry for optimizing metabolic stability and bioavailability in drug candidates. Shows potential in central nervous system therapies due to its ability to cross the blood-brain barrier in preclinical models.
