    摘要: 2′-Deoxyisoguanosine, isosteric analogues and isoguanosine derivatives of formulae I-V, processes for their production via compounds of the general formulae a or b and reaction with aroyl isocyanates or from compounds of the general formulae VI-IX by photochemical irradiation. A further production process is the conversion of deoxyguanosines or guanosines by means of persilylation, reaction with ammonia and deamination in the 2 position. The compounds are suitable as pharmaceutical agents with antiviral efficacy.

    摘要: Process for the production of oligonucleotides of formula II, in which the exocyclic amino groups of the bases adenine, guanine, cytosine, 7-deazaadenine and 7-deazaguanine carry N-phenylacetyl groups, are used for oligonucleotide synthesis, wherein in a first step a starting nucleotide is bound to a solid carrier, subsequently the desired oligonucleotide is synthesized by stepwise coupling with appropriately activated further monomeric nucleotide building blocks of the general formula I with the above-mentioned meanings, if desired, trivalent phosphorus is oxidized to pentavalent phosphorus during and after the synthesis, the oligonucleotide is cleaved from the carrier and the 5' protecting groups are cleaved off. The phenylacetyl functional groups that protect exocyclic NH.sub.2 groups of the bases can be cleaved off in a mild way with penicillin amidohydrolase (EC 3.5.1.11).

    摘要: Oligodeoxyribonucleotides in which at least two 2′-deoxy-&bgr;-D-erythro-pentofuranosyl groups are replaced by 2′-deoxy-&bgr;-D-threo-pentofuranosyl groups at both the 5′ end and 3′ end, and oligodeoxyribonucleotides in which at least 20% of the 2′-deoxy-&bgr;-D-erythro-pentofuranosyl groups in consecutive nucleotide building blocks are replaced by 2′-deoxy-&bgr;-D-threo-pentofuranosyl groups and which are composed of 6 to 100 nucleotide building blocks, are suitable for the inhibition of the expression of viral genes and oncogenes by the antisense principle and can be used for the production of pharmaceutical agents with antiviral activity.
