Ribose-modified adenosine analogues as potential partial agonists for the adenosine receptor
Van der Wenden,Von Frijtag Drabbe Kunzel,Mathot,Danhof,Ijzerman,Soudijn
, p. 4000 - 4006 (1995)
We have adopted a practical three-step route for the synthesis of 2'- and 3'-deoxy analogues of N6-substituted adenosines: protection of the hydroxyl groups, replacement of the N6-amino by a better leaving group, and combined deprote
Spectral assignments and reference data complete1H and 13C NMR spectral assignment of α- And β-adenosine, 2′-deoxyadenosine and their acetate derivatives
Ciuffreda,Casati,Manzocohi
, p. 781 - 784 (2007)
1H and 13C NMR chemical shifts of α- and β-anomers of adenosine, 2′-deoxyadenosine and their acetate derivatives were completely and definitely assigned using the concerted application of one- and two-dimensional experiments (gCOSY, gNOESY, gHSQC and gHMBC). The influence of the stereochemistry of the purine base on the NMR data of the hydrogen and carbon atoms of the furanose moiety was estimated. Copyright

Fossils of extinct species allow us to reconstruct the process of Darwinian evolution that led to the species diversity we see on Earth today. The origin of the first functional molecules able to undergo molecular evolution and thus eventually able to create life, are largely unknown. The most prominent idea in the field posits that biology was preceded by an era of molecular evolution, in which RNA molecules encoded information and catalysed their own replication. This RNA world concept stands against other hypotheses, that argue for example that life may have begun with catalytic peptides and primitive metabolic cycles. The question whether RNA or peptides were first is addressed by the RNA-peptide world concept, which postulates a parallel existence of both molecular species. A plausible experimental model of how such an RNA-peptide world may have looked like, however, is absent. Here we report the synthesis and physicochemical evaluation of amino acid containing adenosine bases, which are closely related to molecules that are found today in the anticodon stem-loop of tRNAs from all three kingdoms of life. We show that these adenosines lose their base pairing properties, which allow them to equip RNA with amino acids independent of the sequence context. As such we may consider them to be living molecular fossils of an extinct molecular RNA-peptide world.
DNA binding and cleavage studies of copper(II) complexes with 2′-deoxyadenosine modified histidine moiety
Borowska, Justyna,Sierant, Malgorzata,Sochacka, Elzbieta,Sanna, Daniele,Lodyga-Chruscinska, Elzbieta
, p. 989 - 1004 (2015/09/01)
This work is focused on the study of DNA binding and cleavage properties of 2′-deoxyadenosines modified with ester/amide of histidine (his6dA ester, his6dA amide) and their copper(II) complexes. To determine the coordination mode of
