CAY10572 is primarily utilized in research settings as a potent and selective inhibitor of the enzyme diacylglycerol kinase alpha (DGKα). Its application is significant in studying cellular signaling pathways, particularly those involving lipid metabolism and immune cell function. By inhibiting DGKα, it helps researchers understand the role of this enzyme in T-cell activation, cancer progression, and immune responses. This compound is also used to explore potential therapeutic strategies for diseases where DGKα activity is dysregulated, such as certain cancers and autoimmune disorders. Its specificity makes it a valuable tool for elucidating the molecular mechanisms underlying these conditions.
