PtdIns-（3,4,5）-P3（1,2-二己酰基）（铵盐）

磷脂酰肌醇（PtdIns）磷酸酯占总膜磷脂的一小部分，但它们在细胞信号的产生和传递中起着至关重要的作用。PtdIns-（3,4,5）-P3，也称为PIP3，对PI特异性磷脂酶C（PLC）的切割具有抗性。因此，它很可能本身就可以作为信号调节剂而不是肌醇四磷酸酯的来源发挥作用​​。PIP3可以充当锚定信号蛋白的信号蛋白的结合锚点（普列克底物蛋白同源性）域。蛋白质与PIP3的结合对于细胞骨架重排和膜运输非常重要。PtdIns-（3,4,5）-P3（1,2-二己酰基）是天然PIP3的合成类似物，在sn-1和sn-

The phosphatidylinositol (PtdIns) phosphates represent a small percentage of total membrane phospholipids, but they play a crucial role in the generation and transmission of cellular signals. PtdIns-(3,4,5)-P3, also known as PIP3, is resistant to cleavage by PI-specific phospholipase C (PLC). Thus, it is likely to function in signal transduction as a modulator in its own right, instead of a source of inositol tetraphosphates. PIP3 can serve as an anchor for the binding of signal transduction proteins bearing pleckstrin homology (PH) domains. Protein binding to PIP3 is important for cytoskeletal rearrangement and membrane trafficking. PtdIns-(3,4,5)-P3 (1,2-dihexanoyl) is a synthetic analog of natural PIP3 with saturated C6 fatty acids at sn-1 and sn-2 positions. The compound features the same inositol and diacylglycerol (DAG) stereochemistry as the the natural compound. The short fatty acid chains of this analog give it different physical properties from naturally-occurring PIP3, including higher solubility in aqueous media.
