Significance
Drug resistance and side effects in children observed with tamiflu motivated this search for new neuraminidase inhibitors directed towards a treatment for avian influenza. Conventional methodology was used to convert d-xylose into tamiflu as well as some phosphonate congeners (e.g., tamiphosphor and I).
Comment
The phosphonate congeners are significantly more potent than the carboxylate congeners against the wild-type neuraminidases H1N1 and H5N1. Moreover, analogue I is a 19 nM inhibitor for the H274Y mutant of H5N1 neuramindase.
