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 ... -
Branched-chain C-cyano pyranonucleosides: Synthesis of 3 '-C-cyano & 3 '-C-cyano-3 '-deoxy pyrimidine pyranonucleosides as novel cytotoxic agents
(2011)This report describes the total and facile synthesis of 3'-C-cyano & 3'-C-cyano-3'-deoxy pyrimidine pyranonucleosides. Reaction of 3-keto glucoside 1 with sodium cyanide gave the desired precursor 3-C-cyano-1,2:5,6-di-O- ... -
Efficient synthesis of exomethylene- and keto-exomethylene-D-glucopyranosyl nucleoside analogs as potential cytotoxic agents
(2011)A novel series of exomethylene- and keto-exomethylene-D-glucopyranonucleosides with thymine, uracil, and 5-fluorouracil as heterocyclic bases have been designed and synthesized. Wittig condensation of the 3-keto glucoside ... -
Fluoro-ketopyranosyl nucleosides: Synthesis and biological evaluation of 3-fluoro-2-keto-beta-D-glucopyranosyl derivatives of N-4-benzoyl cytosine
(2007)1,2:5,6-Di-O-isopropylidene-ot-D-glucofuranose on mild oxidation, reduction, fluorination, and deisopropylidenation followed by acetylation gave peracetylated 3-deoxy-3-fluoro-D-glueopyranose. This was coupled with silylated ... -
Synthesis and biological evaluation of unsaturated keto and exomethylene D-arabinopyranonucleoside analogs: Novel 5-fluorouracil analogs that target thymidylate synthase
(2011)The synthesis of pyrimidine unsaturated keto and exomethylene arabinopyranonucleoside analogs as potential antitumor and antiviral agents is described. Commercially available 1,2,3,4-tetra-O-acetyl-D-arabinopyranose (1) ... -
Synthesis of 4,6-dideoxy-3-fluoro-2-keto-beta-D-glucopyranosyl analogues of 5-fluorouracil, N-6-benzoyl adenine, uracil, thymine, N-4-benzoyl cytosine and evaluation of their antitumor activities
(2010)The synthesis of the unsaturated 4,6-dideoxy-3-fluoro-2-keto-beta-D-glucopyranosyl nucleosides of 5-fluorouracil (6a), N-6-benzoyl adenine (6b), uracil (6c), thymine (6d) and N-4-benzoyl cytosine (6e), is described. ... -
Synthesis, Antiviral and Cytostatic Evaluation of Unsaturated Exomethylene and Keto D-Lyxopyranonucleoside Analogues
(2009)This report describes the synthesis of unsaturated exomethylene lyxopyranonucleoside analogues as potential biologically active agents. Commercially available 1,2,3,4-tetra-O-acetyl-alpha-D-lyxopyranose 1 was condensed ... -
Unsaturated fluoro-ketopyranosyl nucleosides: Synthesis and biological evaluation of 3-fluoro-4-keto-beta-D-glucopyranosyl derivatives of N(4)-benzoyl cytosine and N(6)-benzoyl adenine
(2008)The protected beta-nucleosides 1-(2,4,6-tri-O-acetyl-3-deoxy-3-fluoro-beta-D-glucopyranosyl)-N(4)-benzoyl cytosine (2a) and 9-(2,4,6-tri-O-acetyl3-deoxy-3-fluoro-O-D-glucopyranosyl)-N6-benzoyl adenine (2b), were synthesized ...
