A new amphiphilic, high-molecular weight poly (N-acryloylmorphorine) (PAcM)
polymer has been used to be linked to oligonucleotide chains through a liq
uid-phase stepwise synthesis. This new conjugate has been investigated for
its melting property, nuclease stability and capacity to elicit RNase H act
ivity. Its antisense activity against an HIV-1 target has been also evaluat
ed.
