  Synthesis of N-Acetylglucosamine-Modified ara-C and Its Effect on Ovarian Cancer Cells

  摘要：

  1-beta-D-Arabinofuranosylcytosine (ara-C) was modified by reaction of tetra-N-acetylchitotetraose ((GlcNAc)(4) using the transglycosylation activity of thermostable chitinase (EC 3.2.1.14) from Bacillus licheniformis X-7u. The structure of the modified ara-C was determined to be either beta 1-3'- or beta 1-5'-linked GlcNAc-ara-C or (GlcNAc)(2)-ara-C. The total yield of these glycosylated ara-Cs was about 10%. GlcNAc-ara-C and (GlcNAc)(2)-ara-C depressed the growth of G-401 cancer cells, while 5-O-beta-D-galactopyranosyl-beta-D-arabinofuranosylcytosine (Gal-ara-C) had no effect on G-401 cells.
