A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

To expand the chemical array available for DNA sequences in the context of in vitro selection, I present herein the synthesis of five nucleoside triphosphate analogues containing side chains capable of organocatalysis. The synthesis involved the coupling of L-proline-containing residues (dU(tP)TP and dU(cP)TP), a dipeptide (dU(FP)TP), a urea derivative (dU(Bpu)TP), and a sulfamide residue (dU(Bs)TP) to a suitably protected common intermediate, followed by triphosphorylation. These modified dNTPs were shown to be excellent substrates for the Vent (exo(-)) and Pwo DNA polymerases, as well as the Klenow fragment of E. coli DNA polymerase I, although they were only acceptable substrates for the 9°N(m) polymerase. All of the modified dNTPs, with the exception of dU(Bpu)TP, were readily incorporated into DNA by the polymerase chain reaction (PCR). Modified oligonucleotides efficiently served as templates for PCR for the regeneration of unmodified DNA. Thermal denaturation experiments showed that these modifications are tolerated in the major groove. Overall, these heavily modified dNTPs are excellent candidates for SELEX.
