摘要:
A method is described for improving the pharmacokinetics of a drug in a subject, by co-administering oligomers, preferably PMO's (phosphorodiamidate morpholino oligonucleotides), antisense to RNAs encoding drug-metabolizing enzymes, particularly p450 enzymes. The oligomers reduce production of the drug-metabolizing enzymes, which extends drug half-life and effectiveness and/or decreases drug toxicity.
摘要:
The present invention provides a method for targeting a particular mRNA sequence in vivo by oral administration of a morpholino antisense compound having uncharged phosphorus-containing backbone linkages. Also disclosed is a non-invasive method of detecting and quantitating the in vivo presence of RNA containing one or more selected target sequences. The method includes administering to a subject a nuclease-resistant antisense oligomer which hybridizes by Watson-Crick base pairing to a region of the target RNA with a Tm substantially greater than 37° C. The oligomer is able to complex intracellularly with target RNA, and is released from intracellular sites as a nuclease-resistant heteroduplex, which can then be measured in a body fluid sample, e.g., urine.
摘要:
This invention relates to a new and improved pharmaceutical composition and method for delivery of therapeutic or bioactive agents. The methods and composition of the invention can be used with several therapeutic or bioactive agents and can achieve site-specific delivery of a therapeutic or biologically-active substance. This can allow for lower doses and for improved efficacy with drugs, particularly agents such as oligonucleotides which are plagued with problems in achieving therapeutic levels at targeted sites.
摘要:
Compositions and methods for enhancing delivery of molecules, e.g. biological agents, into cells are described. The composition is a conjugate of the biological agent, preferably a nucleic acid analog having a substantially uncharged backbone, covalently linked to a peptide transporter moiety as described. Conjugation of the peptide transporter to a substantially uncharged nucleic acid analog, such as a morpholino oligomer, is also shown to enhance binding of the oligomer to its target sequence and enhance antisense activity.

A method of inhibiting replication of a flavivirus in animal cells, and an oligonucleotide compound for use in the method are disclosed. The oligonucleotide analog (i) has a nuclease-resistant backbone, (ii) is capable of uptake by the cells, (iii) contains between 8-40 nucleotide bases, and (iv) has a sequence of at least 8 bases complementary to a region of the virus' positive strand RNA genome that includes at least a portion of SEQ ID NOS:1-4.

摘要:
A method and antisense compound for inhibiting the growth of pathogenic bacterial cells are disclosed. The compound contains no more than 12 nucleotide bases and has a targeting nucleic acid sequence of no fewer than 10 bases in length that is complementary to a target sequence containing or within 10 bases, in a downstream direction, of the translational start codon of a bacterial mRNA that encodes a bacterial protein essential for bacterial replication. The compound binds to a target mRNA with a Tm of between 50° to 60° C. The relatively short antisense compounds are substantially more active than conventional antisense compounds having a targeting base sequence of 15 or more bases.
