Novel reagents for terminal phosphorylation and thiophosphorylation of synthetic oligonucleotides
摘要:
Two novel phosphoramidite building blocks and a solid support that allow an efficient solid-phase phosphorylation or thiophosphorylation of synthetic oligonucleotides were developed. The utility of these synthetic tools was demonstrated in the preparation of 5 '- or 3 ' -thiophosphorylated oligonucleotides, which were subsequently labeled at the termini with fluorescent reporters.

Selectively functionalized oligonucleotides, methods for making same, and compounds useful therefor are disclosed. The oligonucleotides can be selectively functionalized with a first conjugate group at the 3′-terminial position and optionally functionalized with a second conjugate group at the 5′-terminal position and/or one or more internucleotides. Alternatively, the oligonucleotides can be selectively functionalized with a first conjugate group at the 5′-terminal position and optionally functionalized with a second conjugate group at one or more internucleotides. In yet another embodiment, the oligonucleotides can be functionalized with a first conjugate group at one or more internucleotides and with a second conjugate group at one or more different internucleotides.
