DAG激酶抑制剂是DGK（二酰基甘油激酶； DAG激酶）的抑制剂，可用于阐明蛋白激酶C（PKC）的作用。据报道，DAG激酶抑制剂还可以在一些系统中抑制DGK，例如分离的血小板膜，完整的血小板和幽灵红细胞。其他报告显示以浓度依赖性方式抑制。如使用无细胞系统报道的那样，DAG激酶抑制剂还可能抑制其他途径，例如NADPH，并可能干扰脂质介导的氧化酶成分的组装过程。据报道，这种特定的同工型R59949可能表现出对DGK-α的选择性抑制。 DAG Kinase Inhibitor is an inhibitor of DGK (Diacylglycerol kinase; DAG Kinase) and is useful for elucidating the roles of protein kinase C (PKC). DAG Kinase Inhibitor 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 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-α.
