M. Manoharan et al., CHOLIC-ACID OLIGONUCLEOTIDE CONJUGATES FOR ANTISENSE APPLICATIONS, Bioorganic & medicinal chemistry letters, 4(8), 1994, pp. 1053-1060
To improve the pharmacokinetics of antisense oligonucleotides, cholic
acid was conjugated to several biologically active sequences. Physical
and biological properties of the conjugates were examined. While the
cholic acid conjugation changes the lipophilicity of the oligonucleoti
des, the in vitro biological activity observed was dependent on the di
sease target, cell lines and the method of oligonucleotide treatment.
