FRAX597 is primarily utilized in research settings for its role as a potent and selective inhibitor of p21-activated kinase (PAK). It is extensively studied in the context of cancer research, where it helps to understand the signaling pathways involved in tumor growth and metastasis. By inhibiting PAK, FRAX597 can suppress the proliferation and survival of cancer cells, making it a valuable tool for exploring potential therapeutic strategies. Additionally, it is used in studies focused on neurological disorders, as PAK signaling is implicated in brain development and function. Researchers also employ FRAX597 to investigate its effects on cytoskeletal reorganization and cell motility, which are critical processes in various physiological and pathological conditions.
