PIK-93 is primarily used in biomedical research as a selective inhibitor of phosphoinositide 3-kinase (PI3K), particularly targeting the PI3Kα and PI3Kγ isoforms. It is widely applied in studies exploring cell signaling pathways related to cell growth, survival, and migration. Due to its inhibitory action, PIK-93 helps researchers investigate the role of PI3K in cancer development, making it a valuable tool in oncology research. It has also been used to study inflammatory responses, as PI3Kγ is involved in immune cell activation and recruitment. In addition, PIK-93 serves as a lead compound for developing more potent and selective PI3K inhibitors for potential therapeutic use. Its application extends to diabetes and cardiovascular research, where PI3K signaling plays a regulatory role in insulin response and heart function.
