Abstract

Functionally-modified oligonucleotide analogues comprising modified intersubunit linkages and/or modified 3′ and/or 5′-end groups are provided. The disclosed compounds are useful for the treatment of diseases where inhibition of protein expression or correction of aberrant mRNA splice products produces beneficial therapeutic effects.
