protein of influenza virus A/chicken/Germany/27 (Weybridge strain; H7N7) were measured for the first time using an assay based on quenching of Trp-41 fluorescence by His-37 protonation, and their antiviral potencies were evaluated against the replication of influenza virus A H2N2 and H3N2 subtypes and influenza virus B in MDCK cells. Of the various 2-alkyl-2-aminoadamantanes, and analogues, spiro[piperidine-2
Compounds useful for treating and preventing viral infections including influenza are disclosed. Methods of treating or preventing viral infections, including influenza A infections are disclosed. Specifically, aminoadamantane derivatives that are structurally analogous to amantadine, including spirocyclic compounds, are provided for the treatment of amantadine-insensitive influenza infection in a subject.

Approaches to primary tert-alkyl amines as building blocks
Primary tert-alkyl amines include analogues of amantadine, a fragment commonly linked to pharmacophoric groups to enhance biological activity. The preparation of primary tert-alkyl amines is considered to be a difficult problem. Four synthetic procedures, some of which have been previously reported for the synthesis of amines with primary (RCH2NH2) or secondary (RR'CHNH2) alkyl and/or aryl groups,
