DAG Kinase Inhibitor II is an inhibitor of DGK (Diacylglycerol kinase DAG Kinase) and is useful for elucidating the roles of protein kinase C (PKC). DAG Kinase Inhibitor II has also been reported to inhibit DGK in several systems such as isolated platelet membranes, whole platelets and ghost erythrocytes. Additional reports have shown to inhibit in a concentration dependent manner. DAG Kinase Inhibitor II may also inhibit other pathways such as NADPH and potentially interfere with the lipid-mediated assembly process of oxidase components as reported using a cell-free system. This particular isoform, R59949, has been reported to potentially exhibit selective inhibition of DGK-alpha.
