Synthesis and properties of cationic 2'-O-[N-(4-aminobutyl)carbamoyl] modified oligonucleotides.

Abstract:

:2'-O-[N-(4-Aminobutylcarbamoyl)]uridine (U(abcm)) was synthesized and incorporated into oligonucleotides. The oligonucleotides incorporating U(abcm) formed more stable duplexes with their complementary and mismatched RNAs than those containing 2'-O-carbamoyluridine (U(cm)). The stability of duplex with a U(abcm)-rG base pair showed higher thermostability than the duplex having unmodified U-rG base pair. The U(abcm) residue showed enhanced resistance to snake venome phosphodiesterase.
