Synthesis of 3-fluoro-6-S-(2-S-pyridyl) nucleosides as potential lead cytostatic agents
(2010)
The 3-deoxy-3-fluoro-6-S-(2-S-pyridyl)-6-thio-beta-D-glucopyranosyl nucleoside analogs 7 were prepared via two facile synthetic routes. Their precursors, 3-fluoro-6-thio-glucopyranosyl nucleosides 5a-e, were obtained by ...
Structure based inhibitor design targeting glycogen phosphorylase b. Virtual screening, synthesis, biochemical and biological assessment of novel N-acyl-beta-D-glucopyranosylamines
(2014)
Glycogen phosphorylase (GP) is a validated target for the development of new type 2 diabetes treatments. Exploiting the Zinc docking database, we report the in silico screening of 1888 N-acyl-beta-D-glucopyranosylamines ...
Keto-fluorothiopyranosyl nucleosides: a convenient synthesis of 2-and 4-keto-3-fluoro-5-thioxylopyranosyl thymine analogs
(2011)
A novel series of fluorinated keto-beta-D-5-thioxylopyranonucleosides bearing thymine as the heterocyclic base have been designed and synthesized. Deprotection of 3-deoxy-3-fluoro-5-S-acetyl-5-thio-D-xylofuranose (1) and ...
STEREOCONTROLLED FACILE SYNTHESIS AND BIOLOGICAL EVALUATION OF (3 ' S) AND (3 ' R)-3 '-AMINO (AND AZIDO)-3 '-DEOXY PYRANONUCLEOSIDES

(2012)
A new series of 4'-C-cyano and 4'-C-cyano-4'-deoxy pyrimidine pyranonucleosides has been designed and synthesized. Commercially available 1,2,3,4,6-penta-O-acetyl-D-mannopyranose (1) was condensed with silylated 5-fluorouracil, ...
A facile, one-step conversion of 6-O-trityl and 6-O-TBDMS monosaccharides into the corresponding formate esters
(2006)
A convenient method has been developed for a facile and high-yield conversion of 6-O-tertbutyldimethylsilyl and 6-O-trityl protected monosaccharides to their formate esters, which may serve as useful intermediates for the ...
Antioxidant activity of a series of fluorinated pyrano-nucleoside analogues of N-4-benzoyl cytosine and N-6-benzoyl adenine
(2007)
Fluorinated nucleoside analogues are known as antitumor, antiviral and chemotherapeutic agents, although the antioxidant activity of this kind of molecules is not yet investigated. In this study we have tested the antioxidant ...
