Application

18:1-2:0 DG (1-oleoyl-2-acetyl-sn-glycerol) has been used as a diacyl glycerol (DAG) analog to test its impact on DAG-sensitive channels in thalamocortical (TC) neurons. It may be used as an internal standard for retention time calibration in ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-QTOF MS)for blood sample lipid quantification. It may also be used as a protein kinase C (PKC) activator in adrenal glands.

Biochem/physiol Actions

1-oleoyl-2-acetyl-sn-glycerol (OAG) has ability to activate protein kinase C (PKC) . It also inhibits TWIK-related acid-sensitive (TASK)-like potassium channels in peripheral arterial chemoreceptors. OAG stimulates 5-lipooxygenase (5-LO) in human polymorphonuclear leukocytes (PMNL). It also inhibits mitochondrial permeability transition pore (MPTP) formation and prevents fatty acid release and necrosis in lung fibroblasts.

General description

18:1-2:0 DG, also called 1-oleoyl-2-acetyl-sn-glycerol (OADG), is a synthetic analog of diacyl glycerol (DAG) and is membrane permeable.

Other Notes

Delivery to cells: Dry samples of diacylglycerol in chloroform, using a stream of nitrogen. Dissolve the residue in an appropriate volume of ethanol or DMSO, then dilute to the desired aqueous medium.

Effective concentration: Most biological responses saturate at 20 to 250 μM sn-1,2-dioctanoylglycerol. Only sn-1,2 isomers appear to be active.

Precaution: Since short chain Diacylglycerols mimic effects of the tumor-promoting phorbol diesters in a number of biological systems, extra care should be employed in their handling. Treatment of solutions, vessels and other articles with 1N NaOH before washing or discarding will destroy diacylglycerols.

Storage and Stability

Diacylglycerols are conveniently stored in chloroform solutions in glass vials with PTFE-lined caps at -20°C. Under these conditions acyl migration is minimal. Avoid plastic when handling chloroform solutions.
