6-Pyrazolylpurine as an Artificial Nucleobase for Metal-Mediated Base Pairing in DNA Duplexes

The artificial nucleobase 6-pyrazol-1-yl-purine (6PP) has been investigated with respect to its usability in metal-mediated base pairing. As was shown by temperature-dependent UV spectroscopy, 6PP may form weakly stabilizing 6PP-Ag(I)-6PP homo base pairs. Interestingly, 6PP can be used to selectively recognize a complementary pyrimidine nucleobase. The addition of Ag(I) to a DNA duplex comprisi...

Metal-mediated base pairing within the simplified nucleic acid GNA.

Hydroxypyridone and pyridopurine homo- and hetero-base pairs have been investigated in the context of duplex GNA (glycol nucleic acid). Phosphoramidites for automated GNA solid phase synthesis were synthesized economically in a few steps starting from commercially available enantiopure glycidol. Similar to their behavior in DNA, the hydroxypyridone and pyridopurine homo-base pairs display a met...

A family of "click" nucleosides for metal-mediated base pairing: unravelling the principles of highly stabilizing metal-mediated base pairs.

A family of artificial nucleosides has been developed by applying the Cu(I)-catalyzed Huisgen 1,3-dipolar cycloaddition. Starting from 2-deoxy-β-D-glycosyl azide as a common precursor, three bidentate nucleosides have been synthesized. The 1,2,3-triazole involved in all three nucleobases is complemented by 1,2,4-triazole (TriTri), pyrazole (TriPyr), or pyridine (TriPy). Molecular structures of ...

Nucleobase analogs for degenerate hybridization devised through conformational pairing analysis.

A conformational pairing analysis was used to devise nucleobase analogs capable of forming nonselective and energetically favorable base pairs opposite either the purine or the pyrimidine constituents of nucleic acids. 5-methylisocytosine and isoguanine were conceived as a degenerate pyrimidine and a degenerate purine, respectively. Data from previous DNA duplex melting experiments verified tha...

Nucleobase pairing in expanded Watson-Crick-like genetic information systems.

To guide the design of alternative genetic systems, we measured melting temperatures of DNA duplexes containing matched and mismatched nucleobase pairs from natural and unnatural structures. The pairs were analyzed in terms of structural features, including nucleobase size, number of hydrogen bonds formed, the presence of uncompensated hydrogen bonding functional groups, the nature of the bond ...
