Determination of neuraminic acid in cerebral tissues
Analytical Biochemistry, 1960Abstract The concentration of neuraminic acid was determined in the gray matter of the insular and temporal cortex as well as of the basal ganglia, and in the white matter of normal autopsy human brains. Samples from the cerebral tissues were separated into two fractions: a water-soluble lipid and a lipid-free residue.

Inhibition of neuraminidase with neuraminic acid C -glycosides
Bioorganic & Medicinal Chemistry Letters, 2000Neuraminic (sialic) acid based alpha-C-glycosides have been synthesized and their inhibitory activity towards bacterial neuraminidase (sialidase) was examined. While some C-glycosides were found to be potent inhibitors (Ki 15-30 microM) of this neuraminidase, others afforded no measurable activity.

Dialysable Neuraminic Acid in Human Cerebrospinal Fluid
Nature, 1962BECAUSE of the presence of interfering sugars in great excess, it has not been possible heretofore to determine with any certainty in other laboratories as well as our own1 whether neuraminic acid occurs in dialysable form in cerebrospinal fluid. Recent methods developed in this laboratory for the quantitative fractionation of all the carbohydrate ...

Characterization of visna virus envelope neuraminic acid
Journal of Virology, 1977Visna virus particles inhibit influenza virus hemagglutination in an assay for neuraminic acid-containing viruses. Pretreatment of visna virus with neuraminidase abolished hemagglutination inhibition activity but did not significantly affect attachment, infectivity, or virus-induced cell fusion in sheep choroid plexus cell monolayers.

Circular dichroism of oligosaccharides containing neuraminic acid
Biochemistry, 1975In order to test the usefulness of circular dichroism in stereochemical and structural studies of oligosaccharides of glycoproteins, we measured the circular dichroism (CD) for N-acetylneuraminic acid (NAcNA) and several derivates. By acidic mathanolysis, we have prepared the deacetylated methyl ester, methyl glycoside of NAcNA, as well as a saponified

8-O-Sialylation of Neuraminic Acid
Journal of the American Chemical Society, 1998Synthesis of Neu5Acα(2−3)Galβ(1−4)Glc and Neu5Acα(2−8)Neu5Ac derivatives 12α and 14α, from lactose derivative 6 and 2,3-dehydro-Neu5Ac derivative 7, respectively, with anchimerically assisted Neu5Ac donor 3e, 3f, or 3g has been studied. Reaction of halogenose 3e, having a 3-phenoxythiocarbonyloxy moiety as the assisting group, afforded with 6 and 7 in ...

Cerebrospinal Fluid Neuraminic Acid Deficiency in Schizophrenia
Archives of Neurology And Psychiatry, 1958With the thought that metabolic disturbances nuclear to the schizophrenic process might best be studied in the central nervous system itself, the attention of this laboratory has been directed to certain little-known chemical constituents of the brain and cerebrospinal fluid.
