Stereoselective synthesis of 2-thioglycosides of N-acetylneuraminic acid
Carbohydrate Research, 1989Treatment of methyl 5-acetamido-2,4,7,8,9-penta-O-acetyl-3,5-dideoxy-β-d-glycero-d-galacto-2-nonulopyranosonate (1) severally with thiophenol, phenylmethanethiol, and ethanethiol in the presence of boron trifluoride etherate gave the corresponding 2-thio-β-glycosides 3–5.

Methylumbelliferyl-N-acetylneuraminic acid sialidase in human liver
Biochemical Medicine, 1984Human liver sialidase was measured using methylumbelliferyl-N-acetylneuraminic acid as a substrate. The enzyme activity was linear for only 20 min and linearity was not improved by adding albumin, CaCl2, dithiothreitol, or Ep-459. The optimal pH was 4.5 and the apparent Km value, approximately 0.090 mM.

CMP-N-acetylneuraminic Acid Hydroxylase
2009CMP-N-acetylneuraminic acid (CMP-NeuAc) hydroxylase catalyzes the hydroxylation of CMP-NeuAc to CMP-N-glycolylneuraminic acid (CMP-NeuGc) in the presence of hydrogen donor (NADH), cytochrome b5, and NADH-cytochrome b5 reductase (Kozutsumi et al. 1990; Kawano et al. 1994). This biosynthetic step is the rate limiting reaction for the expression of NeuGc,
