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.

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.

Some Observations on Certain Mucoproteins containing Neuraminic Acid
Nature, 1959IT is now well established1–4 that mucoproteins, particularly those containing neuraminic acids, play a major part in the natural defences of the human body. With the object of determining what part is played by such mucoproteins in human cancer we have assessed the amount and distribution of mucoproteins containing neuraminic acid by determination of ...

5-Azido neuraminic acid thioglycoside as sialylation donor
Carbohydrate Research, 20025-Azido neuraminic acid thioglycoside with O-benzyl protecting groups was synthesized. The sialylations of this new donor type showed good alpha-selectivities for certain primary hydroxyls.

Neuraminic Acids/Sialic Acids (N-acetyl- and N-glycolylneuraminic Acid)
2020Currently, the three domains in life include eukaryote, archaea, and bacteria to organize life as representatives. Archaea and bacteria consist of organisms having prokaryotic cells or prokaryotes. Domain eukaryote includes kingdom plantae, kingdom fungi, kingdom animalia, and protists. Only protists include multiple kingdoms.
