Neuraminidase inhibitors
Block influenza virion release

High-yield clue
Neuraminidase inhibitors stop cleavage of sialic acid so new virions stay stuck to the host cell and cannot spread.
Overview
An antiviral class (oseltamivir, zanamivir, peramivir) whose mechanism concept is blocking the influenza surface enzyme neuraminidase, studied to connect viral enzyme structure to virion release.
Classification
- Antiviral
- Sialic-acid analog
- Influenza A and B activity
- Neuraminidase (N-spike) target
Lab & identification clues
- Neuraminidase enzyme cleaves host-cell sialic acid vocabulary
- Influenza has both hemagglutinin (H) and neuraminidase (N) spikes
- Resistance vocabulary tied to neuraminidase active-site mutations
Associations
- Influenza virus release mechanism concept
- Seasonal influenza study framing
- H and N surface glycoprotein antigen vocabulary
Commonly confused with
- M2 ion-channel blockers (amantadine)
- Baloxavir (endonuclease inhibitor)
