Abstract
Chromogenic derivatives of N-acetylneuraminic acid modified in the 4-position to contain a hydrogen atom, a fluorine atom, a methoxy group, or an ethoxy group are used as substrates in colorimetric assays for human influenza neuraminidase activity in clinical specimens for the purpose of selectively diagnosing influenza infection. The substrates may exhibit different reactivity with the different types of influenza neuraminidases, thus enabling one to discern the specific type of influenza infection and prescribe appropriate treatment and/or supportive therapy therefor.
