  • DOPI-3,4-P2
  • Phosphatidylinositol-3,4-bisphosphate C-8

The phosphatidylinositols (PtdIns) represent a small percentage of total membrane phospholipids. However, they play a critical role in the generation and transmission of cellular signals.1,2 PtdIns-(3,4)-P2 (1,2-dioctanoyl) is a synthetic analog of natural PtdIns featuring C8:0 fatty acids at the sn-1 and sn-2 positions. The compound contains the same inositol and diacylglycerol (DAG) stereochemistry as the natural compound. The natural compound is the product of phosphorylation-dephosphorylation involving PtdIn 3-kinase and 5-phosphatases. The 3D-phosphorylated PtdIns are resistant to hydrolysis by phospholipase C.3
