Tóm tắt

Herein, we report the synthesis of new oligonucleotide derivatives containing an internucleotide N-caffeine phosphoramide (PN-caffeine) group. This modification was introduced via Staudinger's reaction with an appropriate caffeine azide during standard solid-phase oligonucleotide synthesis. Modified hexathymidylates and oligonucleotides with a heteronucleotide sequence were obtained with a yield of ∼90 %. Physicochemical properties of the new oligonucleotides were analyzed next.
