  Synthesis and binding properties of pyrimidine oligodeoxynucleoside analogs containing neutral phosphodiester replacements: the formacetal and 3'-thioformacetal internucleoside linkages

  摘要：

  The replacement of the phosphodiester linkage with neutral, achiral, nuclease resistant entities is desirable for the development of oligodeoxynucleotide (ODN) analogs as therapeutic agents in either the antisense or antigene modes. Described herein is the use of the formacetal and 3'-thioformacetal connections as phosphodiester backbone analogs. Pyrimidine dimer blocks containing these moieties were synthesized and incorporated into ODNs in an alternating array with phosphodiester bonds, such that the ODNs had seven acetal and seven phosphodiester linkages. The binding properties of the resulting chimeric ODNs to single-stranded (ss) RNA and double-stranded (ds) DNA were then determined. ssRNA binding properties were determined by thermal denaturation (Tm) analysis, and the 3'-thioformacetal ODN/ssRNA duplex showed a 5.5-degrees-C enhancement in Tm relative to the control phosphodiester ODN. The triple helix formation properties of the 3'-thioformacetal and formacetal ODNs were determined by footprint and restriction enzyme inhibition assays. The 3'-thioformacetal ODN binds to dsDNA with an affinity slightly less than the control ODN. The high affinity and specificity of an ODN containing the 3'-thioformacetal for the ssRNA target and dsDNA target suggest that this linkage is a promising analog for both antisense and triple helix therapeutic applications.

  The present invention provides gapped oligomeric compounds comprising from 1 to about 3 internucleoside linkages having one of formulas I to XVI. In certain embodiments, inclusion of from 1 to about 3 internucleoside linkages of one of formulas I to XVI, improves selectivity for a target RNA relative to an off target RNA. In certain embodiments, the improved selectivity also provides an improved toxicity profile. Certain such oligomeric compounds are useful for hybridizing to a complementary nucleic acid, including but not limited, to nucleic acids in a cell. In certain embodiments, hybridization results in modulation of the amount of activity or expression of the target nucleic acid in a cell.

  A series of 15-mer oligodeoxynucleotide analogues were synthesized, and their thrombin inhibitory activities in vitro and in vivo were evaluated. These oligodeoxynucleotide analogues share the same sequence (GGTTGGTGTGGTTGG) but have one or more phosphodiester linkages replaced by a neutral formacetal group. The results obtained from monosubstitutions show that no single phosphodiester group is critical for the thrombin inhibitory activity, suggesting that the interaction between the oligodeoxynucleotide and thrombin is based on a multiple-site charge-charge interaction. Analysis of the effects of different phosphodiester replacements indicates that the backside and left side of the chairlike structure formed by the molecule may be involved in binding with thrombin, presumably by having direct contacts with the anion-binding exosite of the enzyme. For the oligodeoxynucleotides containing two noncontiguous formacetal groups, the effect of the disubstitution is the sum of the effects obtained from the corresponding two monosubstitutions. Infusion of an oligodeoxynucleotide containing four formacetal groups into monkeys showed an increased in vivo anticoagulant effect and an extended in vivo half-life compared to the unmodified oligodeoxynucleotide.
