Acylation of N-acetylneuraminic acid
Chemistry of Natural Compounds, 1967The direct acylation of N-acetylneuraminic acid takes place ambiguously and leads to two reaction products: the acylated γ-lactone and the acylated derivative of the pyranose form of the acid.

Rat pups were administered N-acetylneuraminic acid (NANA) by i.p. injection or via a feeding catheter for eight consecutive days beginning on d 14 of life. All pups were given the identical dose: 1.0 mg on d 1 and 2 and 1.2 mg on the remaining days, or approximately 20 mg/kg body weight per day. A control group was injected i.p. with glucose instead of

N-acetylneuraminic acid and hostile mucus infertility
European Journal of Obstetrics & Gynecology and Reproductive Biology, 1987A total of 39 samples of hostile mucus, as defined by postcoital examination, were examined for N-acetylneuraminic acid (NANA) deficiency, as measured by the enzymatic addition of NANA, spermatozoal penetration and immobilization. Only 56.7% of the mucus samples were deficient in NANA and this did not correlate with spermatozoal penetration or ...

A monoclonal antibody to free N-acetylneuraminic acid
Biochimica et Biophysica Acta (BBA) - General Subjects, 1990A monoclonal antibody (70-A) to free N-acetylneuraminic acid was obtained by immunizing mice with its synthetic beta-glycoside, sodium O-[(5-acetamido-3,5-dideoxy-D-glycero-beta-D-galacto-2- nonulopyranosyl)onate]-(2----3)-1,2-di-O-tetradecyl-sn-glyce rol, followed by fusing the isolated spleen cells with mouse myeloma cells and cloning positive ...

Cultured skin fibroblasts from a patient suffering from generalized N-acetylneuraminic acid storage disease were found to accumulate large amounts (approx. 4.0 mumol/g fresh weight) of free N-acetylneuraminic acid in a lysosome-enriched subcellular fraction.

An improved synthesis of n-acetylneuraminic acid
Carbohydrate Research, 1969Abstract The overall yield and stereoselectivity of the aldol condensation reactions of 2-acetamido-2-deoxy- D -glucose and 2-acetamido-2-deoxy- D -mannose with oxal-acetate at pH 10 are improved by the incorporation of borate ion in the reaction mixture. Borate ion inhibits the alkaline epimerisation of various 2-acylamino-2-deoxyaldoses.

Several C-9 modified N-acetylneuraminic acid derivatives have been synthesised and evaluated as substrates of N-acetylneuraminic acid aldolase. Simple C-9 acyl or ether modified derivatives of N-acetylneuraminic acid were found to be accepted as substrates by the enzyme, albeit being transformed more slowly than Neu5Ac itself.
