摘要:
The invention is related to the detection of a methylated cytosine in a nucleic acid wherein guanidinium hydrogen sulfite is used for the preparation of a solution containing guanidinium ions and sulfite ions and subsequent modification of the nucleic acid. Thereby, a non-methylated cytosine is converted to uracil. The invention further discloses kits for performing the methods of the invention.
摘要:
Nucleoside-5′-triphosphates and phosphoramidites which carry a residue absorbing in the long wavelength region, preferably a carbocyanine group of the general formula (I), on the base portion or on the phosphorus atom in which R1 and R2 each denote hydrogen or together form a phenyl residue; R3 denotes hydrogen if linkage with the nucleotide is via the R4 position or it denotes a —NHCS— group if linkage with the nucleotide is via the R3 position; both R4 and R5, or R5, alone denote an alkylsulfonyl group with n being a number from 3 to 5 or R4 represents a —NHCS— group with n being a number from 3 to 8, as well as the use of the compounds to label, detect and sequence nucleic acids.
摘要:
The invention concerns compounds of the general formula (I) in which i:he residues R1 to R7 have the meanings given in the application as well as methods for their preparation. The compounds are in particular suitable as substrates for RNA or DNA polymerases and can thus be incorporated into RNA or DNA oligonucleotides and are especially suitable for labelling and detecting nucleic acids or for DNA sequencing.
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:
Compounds of the general formula Ia and Ib are described ##STR1## in which R.sup.1 and R.sup.2 are the same or different and represent hydrogen, straight-chain or branched C.sub.1 to C.sub.6 lower alkyl or an aryl group optionally substituted by electron-withdrawing groups, R.sup.3 denotes a cleavable group, W is hydrogen, halogen or a pseudohalogen and at least one of the groups R.sup.4 or R.sup.5 is a group stabilizing the dioxetane structure and at most one of the groups R.sup.4 or R.sup.5 represents hydrogen and X or Y represents oxygen, N-R or C(R).sub.2 in which R has the meanings stated for R.sup.1 and R.sup.2 or represents a mesomeric double bond or a carbonyl group and n denotes the number 0 or 1 and m denotes the number 1 or 2, as well as a process for their production. These compounds are new and can be used as substrates in immunological assays and in DNA diagnostics using activating agents for colour formation.
摘要:
The invention concerns new cationic or polycationic amphiphiles which are capable of forming aggregates with macromolecules, in particular with DNA or RNA, and it concerns their delivery into prokaryotic or eukaryotic cells. Compounds with spermyl-dioleoyloxypropyl structure have proven to be particularly preferable.
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).
