Novel, diverse pyrido [2,3-d] pyrimidine and pyrimido [4,5-d] pyrimidine analogs were synthesized by the reaction of 1,3-substituted-5-cyano uracil derivatives with appropriate nucleophile under mild conditions. Utilising 5-cyano uracil with various substitutions as a substrate leads to rapid synthesis of annulated uracils with diverse biological properties.
Using the RNA transcript as a template, RNA-templated DNA origami structures were constructed by annealing with designed DNA staple strands. RNA-templated DNA origami structures were folded to form seven-helix bundled rectangular structures and six-helix bundled tubular structures. The chemically modified RNA-DNA hybrid origami structures were prepared by using RNA templates containing modified...
Among novel bis-nucleobase-phenanthridinium conjugates bis-uracil analogue stabilized significantly more effective poly-dA-poly-dT and poly-AH(+)-poly-AH(+) than adenine analogue and reference compound . For the alternating poly-dAdT-poly-dAdT however, the binding preference is lost, pointing to the importance of specific interactions of uracils of with homopolynucleotides containing consecutiv...
