Branched-chain sugar nucleosides: stereocontrolled synthesis and bioevaluation of novel 3 '-C-trifluoromethyl and 3 '-C-methyl pyranonucleosides
Kollatos, N.; Manta, S.; Dimopoulou, A.; Parmenopoulou, V.; Triantakonstanti, V. V.; Kellici, T.; Mavromoustakos, T.; Schols, D.; Komiotis, D. (2015)A new series of 3 '-C-trifluoromethyl- and 3 '-C-methyl-beta-D-allopyranonucleosides of 5-fluorouracil and their deoxy derivatives has been designed and synthesized. Treatment of ketosugar 1 with trifluoromethyltrimethylsilane ... -
STEREOCONTROLLED FACILE SYNTHESIS AND BIOLOGICAL EVALUATION OF (3 ' S) AND (3 ' R)-3 '-AMINO (AND AZIDO)-3 '-DEOXY PYRANONUCLEOSIDES
Manta, S.; Parmenopoulou, V.; Kiritsis, C.; Dimopoulou, A.; Kollatos, N.; Papasotiriou, I.; Balzarini, J.; Komiotis, D. (2012)This article describes the synthesis of (3'S) and (3'R)-3'-amino-3'-deoxy pyranonucleosides and their precursors (3'S) and (3'R)-3'-azido-3'-deoxy pyranonucleosides. Azidation of 1,2:5,6-di-O-isopropylidene-3-O-toluenesu ... -
Stereocontrolled synthesis of 4 '-C-cyano and 4 '-C-cyano-4 '-deoxy pyrimidine pyranonucleosides as potential chemotherapeutic agents
Kiritsis, C.; Manta, S.; Parmenopoulou, V.; Dimopoulou, A.; Kollatos, N.; Papasotiriou, I.; Balzarini, J.; Komiotis, D. (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, ... -
Unsaturation: An important structural feature to nucleosides' antiviral activity
Manta, S.; Kiritsis, C.; Dimopoulou, A.; Parmenopoulou, V.; Kollatos, N.; Tsotinis, A.; Komiotis, D. (2014)In the search of effective, selective and nontoxic antiviral agents, a variety of nucleoside analogues have been synthesized, with different functionalities in the carbohydrate moiety and/or the heterocyclic base. Nucleoside ...
