摘要:
This invention presents novel purine-based compounds for inclusion into oligonucleotides. The compounds of the invention, when incorporated into oligonucleotides are especially useful as 'antisense' agents -- agents that are capable of specific hybridization with a nucleotide sequence of an RNA. Oligonucleotides are used for a variety of therapeutic and diagnostic purposes, such as treating diseases, regulating gene expression in experimental systems, assaying for RNA and for RNA products through the employment of antisense interactions with such RNA, diagnosing diseases, modulating the production of proteins, and cleaving RNA in site specific fashions. The compounds of the invention include novel heterocyclic bases, nucleosides, and nucleotides. When incorporated into oligonucleotides, the compounds of the invention can be useful for modulating the activity of RNA.
摘要:
Enzymatic RNA molecules which cleave ICAM-1 mRNA, IL-5 mRNA, rel A mRNA, TNF-α mRNA, RSV mRNA or RSV genomic RNA, or CML associated mRNA, and use of these molecules for the treatment of pathological conditions related to those mRNA-levels; ribonucleosides or nucleotides modified in 2', 3' or 5', methods for their synthesis, purification and deprotection; vectors containing multiple enzymatic nucleic acids, optionally in chimeric form with tRNAs; method for introducing enzymatic nucleic acids into cells by forming a complex with a second nucleic acid, where the complex is capable of taking an R-loop base-paired structure; method for altering a mutant nucleic acid in vivo by hybridization with an oligonucleotide capable of activating ds RNA deaminase, comprising an enzymatic activity or a chemical mutagen. Further are disclosed trans-cleaving or -ligating hairpin ribozymes lacking a substrate RNA moiety, as well as hammerhead ribozymes having an interconnecting loop between base pairs in stem II.

摘要:
On décrit des compositions et des procédés servant à moduler l'activité ARN et ADN. Dans les modes de réalisation préférés, on prépare des compositions non codantes comprenant des parties cibles et des parties réactives. On utilise de préférence des parties réactives qui agissent par le clivage des liaisons phosphorodiesters, par le clivage des liaisons des sucres du squelette, ou par la modification des bases. Les groupes qui améliorent les caractéristiques pharmacolodynamiques et pharmacocinétiques des oligonucléotides sont également utiles dans certains modes de réalisation. On effectue également de préférence l'apport des fonctionnalités réactive et non réactive au sillon mineur formé par l'hybridation de la composition avec l'ARN cible. On décrit également des procédés thérapeutiques, diagnostiques et de recherche. On a prévu des nucléosides thérapeutiques, diagnostiques et de recherche. On a prévu des nucléosides synthétiques et des fragments nucléosides synthétiques utiles à l'élaboration des oligonucléotides et des analogues oligonucléotidiques.
