CAS 55717-54-9: N-Acetyl-9-O-acetylneuraminic acid

9-O-Acetyl-N-acetyl-neuraminic acid is a sialic acid produced by the human body. It can be found in human serum and has been shown to have inhibitory properties against viruses, such as hepatitis B and C viruses. 9-O-Acetyl-N-acetylneuraminic acid binds to the α1-acid glycoprotein in the blood, which can reduce its ability to bind to other molecules. This leads to a lower concentration of 9-O-acetylneuraminic acid in the blood. This molecule also has chemical biology properties that are being studied for their effects on biological processes such as histological analysis, receptor molecule binding, polymerase chain reaction (PCR), and mucin gene transcription. 9-O-Acetylneuraminic acid also has antihistamine activities that may be due to its ability to block histamine receptors or inhibit histamine release.

Applications N,9-O-Diacetylneuraminic Acid is a primary receptor determinant of influenza C virus. References Rogers, G., et al.: J. Biol. Chem., 261, 5947 (1986); Herrler, G., et al.: EMBO J., 4, 1503 (1985);
