  摘要：

  A radioiodinated artificial substrate of N-acetylglucosaminyltransferase V (GnT-V), 2-(4-iodophenyl)ethyl 2-acetamido-2-deoxy-beta-D-glucopyranosyl-(1 -> 2)-alpha-D-mannopyranosyl-(1 -> 6)-beta-D-glucopyranoside (([I-125]1a), was alternatively synthesized by using the glycosylation reaction from the non-reducing end, in which a glycosyl sulfoxide and a thioglycoside were employed as the glycosyl acceptor and donor, respectively. In addition, two derivatives of [I-125]1a having different lengths of alkyl chain ([I-125]1b, [I-125]1c) were prepared in the same way to increase the permeability of the substrates through the cell membrane and into the Golgi apparatus, where GnT-V acts to modify glycoconjugates by transferring N-acetylglucosamine units from UDP-GIcNAc.
