Used as a key intermediate in the synthesis of kinase inhibitors, particularly in pharmaceuticals targeting cancer. It plays a crucial role in the development of drugs that modulate signaling pathways involved in cell proliferation and survival. Its structure allows for selective binding to ATP sites in kinases, making it valuable in creating targeted therapies for leukemia and other malignancies. Also utilized in research for designing new anti-inflammatory and antiviral agents due to its ability to mimic purine bases in biological systems.
