Et. Rump et al., CONJUGATION OF OLIGONUCLEOTIDES WITH STEROID STRUCTURES AND THEIR INTERACTION WITH THE LOW-DENSITY-LIPOPROTEIN, Nucleosides & nucleotides, 16(7-9), 1997, pp. 1223-1226
To induce association with low-density lipoprotein (LDL), antisense ol
igonucleotides were derivatized at their 3' terminus with several ster
oid structures. It was found that only highly lipidic steroids can com
plex the oligonucleotide with LDL.
