SYNTHESIS AND BIOLOGICAL ACTIVITY OF 4′-C-HYDROXYMETHYL-2′-FLUORO-D-ARABINOFURANOSYLPURINE NUCLEOSIDES
摘要:
A series of 4'-C-hydroxymethyl-2'-fluoro-D-arabinofuranosylpurine nucleosides was prepared and evaluated for cytotoxicity in human tumor cell lines. A convenient synthesis of the carbohydrate precursor 4-C-hydroxymethyl-3,5-di-O-benzoyl-2-fluoro-alpha -D-arabinofuranosyl bromide (13) was developed. Coupling of 13 with the sodium salt of 2,6-dichloropurine led to five target purine nucleosides.
