Description générale

2′-(4-Methylumbelliferyl)-α-D-N-acetylneuraminic acid or 4-MUNANA is a synthetic fluorometric substrate that mimics the naturally occurring neuraminidase enzyme substrate. The enzyme-substrate hydrolysis results in the product 4-methylumbelliferone (4-MU), measured fluorometrically.

Application

2′-(4-Methylumbelliferyl)-α-D-N-acetylneuraminic acid or 4-MUNANA is used as a substrate for the development of a microplate-based assay for neuraminidase inhibitors. The fluorogenic substrate 2ʹ-(4-methylumbelliferyl)-α-D-N-acetylneuraminic acid (4-MUNANA) is used to study the molecular mechanisms of aspirin and celecoxib targeting mammalian neuraminidase-1.

Actions biochimiques/physiologiques

Substrate for fluorometric assay of neuraminidase. Used for fluorescent staining of sialidases in PAGE.

Two novel N-acetylneuraminic acid derivatives, luciferyl N-acetylneuraminic acid (1) and luciferyl 4,7-di-O-methyl-N-acetylneuraminic acid (2), were designed and synthesized as substrates for the rapid detection of influenza virus neuraminidase. The sensitivity and specificity of the assays with compound 1 or 2

Many assays aimed to test the inhibitory effects of synthetic molecules, and naturally occurring products on the neuraminidase activity exploit the hydrolysis of 2'-O-(4-methylumbelliferyl)-N-acetylneuraminic acid (4-MUNANA). The amount of the released product, 4-methylumbelliferone (4-MU), is then measured fluorimetrically. The authors

Infection with Brachyspira hyodysenteriae results in mucoid hemorrhagic diarrhea. This pathogen is associated with the colonic mucus layer, mainly composed of mucins. Infection regulates mucin O-glycosylation in the colon and increases mucin secretion as well as B. hyodysenteriae binding sites

Aspirin (acetylsalicylic acid) and celecoxib have been used as potential anti-cancer therapies. Aspirin exerts its therapeutic effect in both cyclooxygenase (COX)-dependent and -independent pathways to reduce tumor growth and disable tumorigenesis. Celecoxib, a selective cyclooxygenase-2 (COX-2) inhibitor, reduces factors that
