The synthesis of bile acid-oligodeoxynucleotide conjugates via the 3-OH gro
up of the bile acids is described. When used in vivo in rats, covalent conj
ugation of an oligodeoxynucleotide via a linker to cholic acid resulted in
an increased biliary excretion of bile acid-oligodeoxynucleotide conjugates
compared to unconjugated oligodeoxynucleotides. (C) 2001 Elsevier Science
