PIK-93 is primarily utilized in biochemical research as a potent and selective inhibitor of phosphoinositide 3-kinase (PI3K) isoforms, particularly p110γ and p110δ. It is extensively employed in studies aimed at understanding the role of PI3K signaling pathways in cellular processes such as growth, proliferation, survival, and metabolism. Researchers use PIK-93 to investigate its effects on cancer cell lines, as PI3K signaling is often dysregulated in various cancers. Additionally, it is applied in immunology research to explore the function of PI3K in immune cell activation and inflammation. PIK-93 serves as a valuable tool for dissecting the molecular mechanisms of PI3K-related diseases and for evaluating potential therapeutic strategies targeting these pathways.
