Sn-1,2-Dioctanoylglycerol丨CAS 60514-48-9

sn-1,2-Dioctanoylglycerol is widely used as a biochemical reagent in cellular and molecular biology, particularly as a functional analog of natural diacylglycerols (DAGs) that participate in intracellular signaling pathways. In research environments, it serves as a potent activator of protein kinase C (PKC), making it instrumental for studying mechanisms of signal transduction, gene expression, membrane dynamics, and cell differentiation. Its well-characterized activity enables controlled stimulation of PKC-dependent responses in immune cells, neuronal systems, and endocrine models. The compound is also used in pharmacological screenings to explore interactions between lipid messengers and their protein targets, supporting drug-discovery efforts in oncology, inflammation, metabolic disorders, and cardiovascular research. Beyond signaling studies, sn-1,2-Dioctanoylglycerol finds use in membrane biophysics, where it acts as a modulator of lipid bilayer organization, aiding investigations into membrane fluidity, vesicle fusion, and lipid–protein interactions. In enzymology, it serves as a substrate or reference compound for lipase, kinase, and phospholipase assays, contributing to the development and optimization of bioanalytical methods. Its amphiphilic nature and controlled acyl chain length also make it useful in formulation science, including studies related to emulsifiers, lipid delivery systems, and bioactive lipid carriers designed for improved solubility and cellular uptake in experimental formulations. In addition, the compound is occasionally employed in metabolism studies to investigate glyceride processing, lipid turnover, and mitochondrial fatty-acid handling, providing insight into metabolic pathway regulation under physiological and pathological conditions.

sn-1,2-Dioctanoylglycerol offers several advantages for researchers across biological, biochemical, and pharmacological disciplines. One of its main benefits is its predictable and reproducible activity as a PKC activator, allowing scientists to induce cellular responses with accuracy and consistency. Compared with endogenous DAGs, which can exhibit rapid turnover and structural variability, this synthetic analog provides better stability and controlled performance, enabling more reliable experimental setups. Its relatively short eight-carbon acyl chains enhance solubility and membrane incorporation, allowing the compound to diffuse efficiently in cell-based systems and produce rapid, uniform biological effects. This manageable hydrophobicity also simplifies preparation and handling, reducing the need for complex solvent systems. As a reference compound, sn-1,2-Dioctanoylglycerol is valuable for standardizing bioassays, improving the quality, comparability, and reproducibility of research data. Its defined stereochemistry permits targeted activation of signaling pathways with minimal off-target interactions, supporting mechanistic studies that require high precision. In membrane research, its tunable bilayer-modulating properties allow investigators to adjust lipid compositions to mimic physiological or stress-related conditions, facilitating clearer insights into membrane behavior and lipid-dependent regulatory mechanisms. For drug development, the compound's ability to mimic endogenous signaling messengers helps researchers model disease-relevant pathways, making it an efficient tool for screening modulators of PKC and related proteins. In applied formulation studies, its amphiphilic profile supports improved dispersion, making it suitable for evaluating lipid-based delivery vehicles and understanding their interactions with biological membranes.
