Hexadecyl methyl glycerol is a synthetic diacylglycerol with a hexadecyl chain at the sn-1 position and a methyl group at the sn-2 position. It inhibits protein kinase C activity in human neutrophils, resulting in prevention of the respiratory burst induced by both phorbol 12,13-dibutyrate and fMLP.
1-O-Hexadecyl-2-O-methyl-sn-glycerol inhibits protein kinase C activity in human neutrophils.
ChEBI: 1-O-palmityl-2-O-methyl-sn-glycerol is an alkylglycerol having palmityl (hexadecyl) and methyl groups located at position2 1 and 2 respectively (the S-enantiomer).
hexadecyl methyl glycerol, also known as amg-c16 with a hexadecyl chain at the sn-1 position, is a novel inhibitor of protein kinase c with ic50 value of about 80 μm [1].protein kinase c is a phospholipid-dependent kinase and the intracellular receptor for phorbol 12-myristate-13-acetate (pma), a substance that activates both the respiratory burst and protein kinase c. pkc enzymes are activated by signals such as increases in the concentration of diacylglycerol (dag) or calcium ions (ca2+) [1].hexadecyl methyl glycerol is a structural analog of diacylglycerol with a hexadecyl chain at the sn-1 position and a methyl group at the sn-2 position. hexadecyl methyl glycerol inhibited the activation of purified protein kinase c by diacylglycerol in the presence of phosphatidylserine. in neutrophilic granulocytes, hexadecyl methyl glycerol inhibited the respiratory burst induced by pdbu in a dose-dependent way. in neutrophils, hexadecyl methyl glycerol inhibited the phosphorylation of purified 47-kda protein, an important substrate of protein kinase c [1].
