General description

Diacylglycerol Kinase Inhibitor I prevents the formation of foreign body giant cell (FBGC). It inhibits the phosphorylation of diacylglycerol to phosphatidic acid. Diacylglycerol Kinase Inhibitor I functions as a serotonin (5-HT) receptor (5-HTR) antagonist. It stimulates apoptosis and autophagy in neuronal cell line NG108-15.

Application

Diacylglycerol Kinase Inhibitor I has been used as an inhibitor to study suppression of T cell function using advanced generation human CAR (chimeric antigen receptors) T cells.

Biochem/physiol Actions

Diacylglycerol kinase inhibitor. Inhibits formation of [38P]1-Oleoxyl-2-acetylglyceryl-3-phosphoric acid (OAPA) in red blood cell membranes: IC50 = 3.3 μM.
