  Synthesis of poly(aspartimide)-based bio-glycoconjugates

  摘要：

  The purpose of this programme was to synthesize and analyze new bioconjugates of interest for the potential inhibition of the influenza virus, using poly(aspartimide) as a polymer support. The macromolecular targets were obtained by attaching various sialic acid-linker-amine compounds to poly(aspartimide). (1)H and (13)C NMR studies were then performed to analyze the degree of incorporation of the sialic acid-linker-amine compounds within the poly(aspartimide). These studies illustrated that the incorporation was dependent on the nature of the spacer between the sugar and the amine functionality. Thus aliphatic spacers favoured the inclusion of sialic acid onto the polymer support whereas compounds having only an aromatic moiety between the sialic acid and the amine could not be easily incorporated.

  A fluorescent probe for sialidase activity detection, is a compound represented by the following general formula or a salt thereof. R 1 , if present, represents the same or different monovalent substituent present on a benzene ring. R 2 and R 3 each independently represent a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or a halogen atom. R 4 and R 5 each independently represent a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or a halogen atom. R 6 represents a hydrogen atom, an alkyl group having 1 to 5 carbon atoms, or a fluorinated alkyl group having 1 to 5 carbon atoms. R 6 ′ represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, and R 6 ′ may form, together with R 3 or R 5 a five to seven-membered heterocyclyl or heteroaryl containing a nitrogen atom to which R 6 ′ is bonded.
