IC-87114 is primarily used in research settings as a selective inhibitor of the delta isoform of phosphoinositide 3-kinase (PI3Kδ). It is widely utilized in studies aimed at understanding the role of PI3Kδ in immune cell signaling and function. Researchers employ this compound to investigate its effects on B-cell activation, proliferation, and survival, which are crucial in autoimmune diseases and certain cancers. Additionally, IC-87114 is used to explore its potential therapeutic applications in conditions like chronic lymphocytic leukemia (CLL) and inflammatory disorders, where PI3Kδ signaling plays a significant role. Its specificity makes it a valuable tool for dissecting the contributions of PI3Kδ in cellular processes and disease mechanisms.
