RI-2 is primarily utilized in biochemical research to study the role of specific enzymes and signaling pathways within cells. It is known for its ability to inhibit certain kinases, making it a valuable tool in understanding cellular processes such as DNA damage response and cell cycle regulation. Researchers use RI-2 to investigate the mechanisms underlying diseases like cancer, where these pathways are often dysregulated. Additionally, it aids in the development of targeted therapies by providing insights into how inhibiting specific enzymes can affect cell behavior and survival. Its application is largely confined to laboratory settings, where it serves as a critical reagent in advancing our understanding of cellular biology and potential therapeutic interventions.
