title: Design and properties of hepatitis C virus antisense oligonucleotides for liver specific drug targeting.
abstract: Different backbone modified antisense oligonucleotides (AS-ODNs) directed against the hepatitis C virus genome were 5'-conjugated to cholesterol, cholic acid or taurocholic acid to enhance liver specific drug targeting and hepatocellular uptake. The lipophilic character of modified AS-ODNs was determined from RP-HPLC retention times and duplex stability was correlated with Tm-values from UV melting curves.
