6-Aza-2'-deoxyuridine |
C8H11N3O5 |
20500-29-2 |
|
DescriptionThe nitrogen atom in place of the methine group at position 6 of the uracil ring in 6-Aza-2'-deoxyuridine (6-aza-dU)1 results in a significant lowering of the pKa of the N3 hydrogen (6.8) vs. that of 2'-deoxyuridine (9.3).2 Unlike dU, 6-aza-dU is deprotonated at neutral pH, thus bestowing the uracil base with a negative charge. Further, there are significant conformational changes imparted by the presence of the 6-aza substitution: 6-Aza-dU has a high-anti conformation and is present in solution with N-type sugar pucker.2 See also 6-Aza-dU CEP, the phosphoramidite version for incorporation of 6-aza-dU residues into oligonucleotides, the nucleoside 6-Azathymidine, and its phosphoramidite 6-Azathymidine CEP.

6-Azathymidine |
C9H13N3O5 |
13410-30-5 |
|
DescriptionThe nitrogen atom in place of the methine group at position 6 of the thymine ring in 6-Azathymidine1 results in a significant lowering of the pKa of the N3 hydrogen (7.0)2 vs. that of thymidine (10.0). Hence, 6-azathymidine will be significantly deprotonated at neutral pH. The phosphoramidite of this nucleoside has been incorporated into oligonucleotides,1 where it imparts nuclease resistance when installed at the 5'-position. Duplexes with DNA or RNA are only slightly destabilized, and heteroduplexes with RNA support RNase-H cleavage. See also the nucleoside 6-Aza-2'-deoxyuridine and the phosphoramidites 6-Aza-dU CEP and 6-Azathymidine CEP. (1) Sanghvi, Y.; Hoke, G. D.; Freier, S. M.; Zounes, M.

Pyrrolo-dC |
C12H15N3O4 |
382137-74-8 |
|
DescriptionPyrrolo-dC is a fluorescent analog of 2'-deoxycytidine (Berry, et. Al, Tetrahedron Lett. 2004, 45 (11), 2457-2461). It is highly fluorescent, exhibiting an emission maximum at 473 nm when incorporated into a 19-mer oligodeoxyribonucleotide, where it base-pairs normally with dG. We also offer pyrrolo-C, a fluorescent analog of cytidine. The phosphoramidites of pyrrolo-C and pyrrolo-dC suitable for oligonucleotide synthesis are available from Berry & Associates (Products BA 0170 and BA 0245) or from Glen Research, our development partner for these products. Glen Research also offers the triphosphates of pyrrolo-C and -dC. We also offer the simple fluorescent pyrrolocytosine heterocycle (i.e., pyrrolo-C aglycone (HC 9060). For photophysical studies on these fluorescent pyrrolopyrimidines, see: Thompson, K. C.; Miyake, N., J. Phys. Chem.
