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.


The present invention relates to antisense antiviral compounds and methods of their use and production in inhibition of growth of viruses of the Orthomyxoviridae family and in the treatment of a viral infection. The compounds are particularly useful in the treatment of influenza virus infection in a mammal. Exemplary antisense antiviral compounds are substantially uncharged, or partially positively charged, morpholino oligonucleotides having 1) a nuclease resistant backbone, 2) 12-40 nucleotide bases, and 3) a targeting sequence of at least 12 bases in length that hybridizes to a target region selected from the following: a) the 5 or 3 terminal 25 bases of the negative sense viral RNA segment of Influenzavirus A, Influenzavirus B and Influenzavirus C; b) the terminal 30 bases of the 5 or 3 terminus of the positive sense vcRNA; c) the 45 bases surrounding the AUG start codon of an influenza viral mRNA and; d) 50 bases surrounding the splice donor or acceptor sites of influenza mRNAs subject to alternative splicing.

Provided are methods of treatment in subjects having progeroid diseases and related conditions which rely upon LMNA-targeted antisense oligonucleotides for reducing expression of one or more aberrantly spliced LMNA mRNA isoforms that encode progerin.


The present invention provides antisense antiviral compounds, compositions, and methods of their use and production, mainly for inhibiting the replication of viruses of the Filoviridae family, including Ebola and Marburg viruses. The compounds, compositions, and methods also relate to the treatment of viral infections in mammals including primates by Ebola and Marburg viruses. The antisense antiviral compounds include phosphorodiamidate morpholino oligonucleotides (PMOplus) having a nuclease resistant backbone, about 15-40 nucleotide bases, at least two but typically no more than half piperazine-containing intersubunit linkages, and a targeting sequence that is targeted against the AUG start site region of Ebola virus VP35, Ebola virus VP24, Marburg virus VP24, or Marburg virus NP, including combinations and mixtures thereof.

Antisense compositions targeted against an mRNA sequence coding for a selected protein, at a region having its 5 end from 1 to about 25 base pairs downstream of a normal splice acceptor junction in the preprocessed mRNA, are disclosed. The antisense compound is RNase-inactive, and is preferably a phosphorodiamidate-linked morpholino oligonucleotide. Such targeting is effective to inhibit natural mRNA splice processing, produce splice variant mRNAs, and inhibit normal expression of the protein.

A method and compound for treating skeletal muscle mass deficiency in a human subject are disclosed. The composition is an oligomer of morpholino subunits and phosphorus-containing intersubunit linkages joining a morpholino nitrogen of one subunit to a 5 exocyclic carbon of an adjacent subunit, contains between 10-40 nucleotide bases, has a base sequence effective to hybridize to an expression-sensitive region of processed or preprocessed human myostatin RNA transcript, identified, in its processed form, by SEQ ID NO:6, and is capable of uptake by target muscle cells in the subject. In practicing the method, the compound is administered in an amount and at a dosage schedule to produce an overall reduction in the level of serum myostatin measured in the patient, and preferably to bring the myostatin level within the a range determined for normal, healthy individuals.
