What is Pleconaril?

Plain description, key identifiers and synonyms

Pleconaril is a small-molecule inhibitor with activity against viruses in the picornaviridae family, including enterovirus and rhinovirus. Pleconaril binds to a hydrophobic pocket in the major capsid protein and prevents uncoating of the viral RNA genome. In enteroviruses it also prevents the virus from attaching itself to the host cell.
