Common Name1,2-Dioctanoyl-sn-glycero-3-phosphate
Description1,2-Dioctanoyl-sn-glycero-3-phosphate is a phospholipid belonging to the class of glycerophospholipids, characterized by its two octanoyl fatty acid chains esterified to the glycerol backbone at the sn-1 and sn-2 positions, with a phosphate group at the sn-3 position. This unique structure contributes to its role in various cellular processes, including membrane dynamics and signaling pathways. It has been implicated in the regulation of the mTOR pathway, where it acts as an activator, influencing cell viability and phosphorylation states. Specifically, studies have shown that the mTOR activator 1,2-dioctanoyl-sn-glycero-3-phosphate (C8-PA) enhances cell viability and counteracts the effects of mTOR inhibitors like rapamycin, which reduces cell viability in certain cancer cell lines (PMID:26287365 ). This highlights its potential involvement in lipid-mediated signaling mechanisms and cellular responses to stress or treatment, underscoring its relevance in metabolic and oncological research.
