Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeting protein kinases involved in inflammatory diseases and cancer. It serves as a scaffold in developing selective inhibitors due to its ability to mimic purine bases, allowing effective binding to ATP-binding sites in enzymes. Also explored in the design of central nervous system agents owing to its capacity to cross the blood-brain barrier. Its tetrahydropyrido ring enhances solubility and metabolic stability, making it favorable for oral drug formulations.
