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 ...
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 ...
Triazole pyrimidine nucleosides as inhibitors of Ribonuclease A. Synthesis, biochemical, and structural evaluation
(2012)
Five ribofuranosyl pyrimidine nucleosides and their corresponding 1,2,3-triazole derivatives have been synthesized and characterized. Their inhibitory action to Ribonuclease A has been studied by biochemical analysis and ...
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 ...
1-(3-Deoxy-3-fluoro-beta-D-glucopyranosyl) pyrimidine derivatives as inhibitors of glycogen phosphorylase b: Kinetic, crystallographic and modelling studies
(2010)
Design of inhibitors of glycogen phosphorylase (GP) with pharmaceutical applications in improving glycaemic control in type 2 diabetes is a promising therapeutic strategy. The catalytic site of muscle glycogen phosphorylase ...
A concise synthesis of 3-fluoro-5-thio-xylo- and glucopyranoses, useful precursors towards their corresponding pyranonucleoside derivatives
(2008)
The chemical synthesis of 1,2,4-tri-O-acetyl-3-deoxy-3-fluoro-5-thio-D-xylopyranose, 1,2,4,6-tetra-O-acetyl-3-deoxy-3 -fluoro-5-thio-alpha(-D-glucopyranose and their corresponding nucleosides of thymine is described. ...
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 ...
Kinetic and in silico analysis of the slow-binding inhibition of human poly(A)-specific ribonuclease (PARN) by novel nucleoside analogues
(2012)
Poly(A)-specific ribonuclease (PARN) is a 3'-exoribonuclease that efficiently degrades poly(A) tails and regulates, in part, mRNA turnover rates. We have previously reported that adenosine- and cytosine-based glucopyranosyl ...
