4-Acetylamino-3-(imidazol-1-yl)-benzoic acids as novel inhibitors of influenza sialidase

Howes, Peter D.,Cleasby, Anne,Evans, Derek N.,Feilden, Helen,Smith, Paul W.,Sollis, Steven L.,Taylor, Neil,Wonacott, Alan J.

, p. 225 - 234 (2007/10/03)

Two methods for the synthesis of 4-acetylamino benzoic acids substituted at the 3-position with imidazoles are described. Many of the compounds are inhibitors of influenza virus sialidases with levels of activity similar to the recently described 4-acetylamino-3-guanidino-benzoic acid (BANA 113).
