4-MUNANA

4-MUNANA is a substrate of influenza virus neuraminidase (NA) with high selectivity and irreversible reaction. In the enzymatic reaction, 4-MUNANA is hydrolyzed by NA to generate fluorescent 4-methylumbelliferone (4-MU). By detecting the fluorescence intensity of 4-MU, quantitative analysis of NA activity can be achieved. 4-MUNANA can be used in influenza-related research, such as screening NA inhibitors, developing new anti-influenza dr_ugs, and studying the infection mechanism of influenza viruses.
