Related to diacylglycerol: Protein kinase C, triacylglycerol

di·ac·yl·glyc·er·ol (DAG),

(dī'as-il'glis'ĕr-ōl),
Diglyceride; glycerol with two esterified acyl moieties, either 1,3-diacylglycerol or 1,2-diacylglycerol; if the two acyl groups are nonidentical, there are four possible isomers of 1,2-diacylglycerol; 1,2-diacylglycerol is an intermediate in the synthesis of triacylglycerols and of lecithin; also serves as a second messenger in stimulating the activity of protein kinase C.

diacylglycerol

/di·acyl·glyc·er·ol/ (di-a″sil-glis´er-ol) any of various compounds of glycerol linked to two fatty acids; they are triglyceride and phospholipid degradation products and are second messengers in calcium-mediated responses to hormones.

The signaling cascades involved in mast cell activation are interaction of an antigen with its specific IgE antibody on mast cell surface, tyrosines phosphophorylation of phospholipase C-g1 (PLC-g1), hydrolysis of phosphatidyl inositol 4,5-biphosphate, formation of inositol triphosphate (IP3) and diacylglycerol (DAG), activation of protein kinase C (PKC), intracellular Ca2+ mobilization by IP3, increase of Ca2+ influx to cytoplasma, activation of mitogen-activated protein kinase (MAP kinases) and G-protein.
PLC[gamma]1 is an enzyme which upon phosphorylation to its active form cleaves the membrane phospholipid, phosphatidylinositol 4, 5 biphosphate (PIP2) to diacylglycerol (DAG) and inositol triphosphate (IP3), which regulate intracellular calcium stores and protein kinase C levels (2).

One of the postulated mechanisms of action of Benfotiamine is that it blocks three major pathways (the hexosamine pathway, the advanced glycation end product formation pathway, and the diacylglycerol (DAG)-protein kinase C (PKC) pathway) by probable removal of glyceryl aldehyde 3-phosphate and fructose 6-phosphate through the activation of the pentos phosphate enzyme transketolase.

Preconditioning causes the activation of various receptors (adenosine A1 receptors, opioid receptors and bradykinin receptors) and the generation of other free radicals, which then transmit signals via G proteins, which lead to the formation of inositol triphosphate, production of diacylglycerol and cause the activation of protein kinases, phosphorylation of ADP and the enhancement of [K.
