1,2-Dimyristoyloxypropane-3-thiophospho(1D-1-myo-inositol) (D-thio-DMPI) was synthesized as a substrate for the continuous spectrophotometric assay of phosphatidylinositol-specific phospholipase C (PI-PLC) from Bacillus cereus. Release of thio-diglyceride is followed by a coupled reaction with 4,4'-dithiopyridine to produce a chromophore, 4 ...

The Journal of Immunology, 1988
Abstract Phosphodiesteric cleavage of phosphatidylinositol-4,5-bisphosphate (PtdIns-4,5-P2) is required for transmembrane signaling by chemoattractants in human polymorphonuclear leukocytes (PMN). Considering the importance of PtdIns-4,5-P2 as a reservoir for second messenger substances, we have characterized the enzyme system that ...

Reversed-phase ion-pair high-performance liquid chromatography of phosphatidylinositols
, 1991Reversed-phase ion-pal, high-performance liquid chromatographic (HPLC) separations of molecular species of phosphatidylinositols (PI) were studied. Mobile phases of acetonitrile-methanol-water containing various tetraalkylammonium phosphates (TAAP) were ...

Cell Calcium, 1982
Recent years have seen a rapid accumulation of information which relates to the idea that receptor-controlled effects on inositol lipid metabolism might somehow be involved in the control of stimulated cells (see refs 1–14 for reviews). Most of these studies have been concerned only with phosphatidylinositol (PtdIns) and have tended to ignore the ...

Alcoholism: Clinical and Experimental Research, 1993
Fatty acid composition of phosphatidylinositols was analyzed in peripheral blood lymphocytes from nine alcoholic patients who were well nourished and without severe acute and chronic liver disease, before and after stimulation with anti-CD3 antibody. Six

Membrane Biochemistry, 1990
The level of biosynthesis and the composition of polyglycerophosphatides (phosphatidylglycerol, phosphatidyglycerolphosphate, and diphosphatidylglycerol or cardiolipin) and phosphatidylinositols were examined in mitochondria and microsomes, respectively,

Metabolism of phosphatidylinositol in the frog retina
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1980The synthesis and the turnover of phosphatidylinositol in frog retinal rod outer segments and microsomes were studied by following the time course of incorporation into lipids of the following radioactive precursors: [3H]glycerol, 33PO4, and [3H]inositol. 1.

Phosphatidylinositol 4-Kinase and Phosphatidylinositol 4-Phosphate 5-Kinase Assays
2013Inositol lipid kinases are perhaps the easiest and most straightforward enzymes in the phosphoinositide pathway to analyze. In addition to monitoring lipid kinase-specific activity, lipid kinase assays can be used to quantify the inositol lipids present in isolated membranes (Jones et al., Methods Mol Biol 462:75-88, 2009).

The phosphatidylinositol response of chondrocytes in culture
Agents and Actions, 1989This study examined the phosphatidylinositol (PI) response in chondrocytes. The levels of 3H-inositol phosphates (IPs) were measured in guinea pig chondrocyte cultures labelled with 3H-myo-inositol and exposed to various inflammatory mediators and known agonists of the PI response, including bradykinin, carbachol, histamine, A23187, or recombinant ...

Synthesis of phosphatidylinositol mannosides (PIMs)
Carbohydrate Research, 2003Two strategies towards the synthesis of phosphatidylinositol mannosides (PIMs) were elaborated which permit selective access to the O-1-, O-2-, and the O-6 position of the myo-inositol residue. Starting materials are 1,2:5,6- and 1,2:4,5-di-O-cyclohexylidene-DL-myo-inositol, respectively.
