AG 1295 is primarily used in biochemical research as a selective inhibitor of platelet-derived growth factor receptor (PDGFR) tyrosine kinase. It is widely applied in studies to understand the role of PDGFR signaling pathways in various cellular processes, including cell proliferation, differentiation, and survival. Researchers utilize AG 1295 to investigate its effects on cancer cells, as PDGFR signaling is often implicated in tumor growth and angiogenesis. Additionally, it is employed in experiments exploring cardiovascular diseases, fibrosis, and other conditions where PDGFR pathways play a critical role. By inhibiting PDGFR, AG 1295 helps elucidate potential therapeutic targets for these diseases.
