Definitions
- the invention relates to nucleosides, nucleotides and oligonucleotides modified in the 3 '- (4'-) position with non-radioactively labeled groups, a process for their preparation and their use.
- Labeled nucleotides have found an extraordinarily large number of applications in genetic engineering, since their use is easier than that of the DNA probes conventionally used as hybridization samples, which are produced by restriction digestion from native genetic material.
- Modified oligonucleotides which are used in the form of so-called “antisense” DNA oligonucleotides, can intervene in a regulating manner in the cell process and thus gain z.
- Labeled oligonucleotides e.g. B. the identification of gene fragments within a gene bank by probing and identifying blotted gene samples from the gene bank with the aid of a labeled oligonucleotide.
- derivatized fluorescent dyes are used as a form of non-radioactive labeling, which offer the possibility of easier and safer handling.
- the fluorescence label was either at the 5 'end of the nucleotide [L. E. Hood, L. M. Smith and C. Heiner, Nature 321, 674 (1986)] or on the nucleobase [J. M. Prober, G.L. Trainor and R.J. Dam, Science 238, 336 (1987)] [G. L. Trainor, Anal. Chem. 62, 418 (1990)].
- This has the disadvantages that only certain polymerases can be used for the synthesis, the acceptance of the triphosphates by the polymerases decreases and that a large excess of substrate is also necessary.
- a fluorescent dye is coupled directly via an amino or thiol group in the 3 'position of a nucleoside, nucleotide or oligonucleotide, and this compound is advantageous for the synthesis of counter-strands in the presence of a template strand and for the detection of genetic strands
- Material in vivo and in vitro can be used (EP 0 490 281).
- these compounds are associated with the disadvantage that the quantum yield is relatively low and the synthesis of the compounds is associated with lengthy, complex chromatographic purification steps.
- the object of the present invention was therefore to make available new non-radioactive labeled nucleosides or nucleotides which do not have the disadvantages of the known compounds.
- the problem is solved by nucleosides or nucleotides of the following general formula modified at the 3 'or 4' position:
- R ' hydrogen, mono-, di- or triphosphate, alkylphosphonate, dialkylphosphinate or phosphoramidite
- X oxygen, nitrogen, carbon or sulfur
- Y oxygen, nitrogen or sulfur
- Z hydrogen, hydroxyl, amino or thiol group
- R spacer group, followed by a non-radioactive, detectable
- Base purine, pyrimidine base or desazapurins or their derivatives, n: 0 or 1.
- the spacer grouping preferably consists of a protected or unprotected bi-, tri- or polyfunctional carboxylic acid, aminocarboxylic acid or a peptide or corresponding derivatives or salts.
- Particularly preferred spacers are all naturally occurring amino acids, such as, for example, glycine or aspartic acid, carboxylic acids or aminocarboxylic acids having 2 to 20 atoms, but also diamines, thiols and amino alcohols.
- Dimers or tetramers of amino acid units have proven to be very particularly suitable for spacer groups; furthermore if the spacer group has a length which corresponds to a carbon lette of 2 to 12 atoms.
- All chemically, physically or biologically detectable groups come into consideration as non-radioactive, detectable groups, so-called reporter molecules.
- reporter molecules Such groupings are known to the person skilled in the art.
- effector molecules are also suitable here, which are capable, directly or after chemical, physical or biological activation, of interactions of a chemical, physical or biological nature with certain target molecules (such as alkylating agents, ⁇ systems of aromatic compounds, enzymes, etc.).
- Examples include the intercalation on DNA / RNA by acetylaminofluorenes, cleavage of DNA / RNA by nucleases or the partial or complete covalent binding of alkyl or alyl groups to DNA / RNA by alkylating agents or psoralenes, and z.
- metal clusters that locally lead to a sharp increase in the cross-section of therapeutically effective electromagnetic radiation.
- luminescent dyes which emit in the wavelength range from approximately 630 to 670 ⁇ m
- enzymes such as peroxidase or alkaline phosphatase and haptens, such as, for example, biotin, come as reporter molecules.
- fluorophers have proven to be suitable here, e.g. B. for Sanger sequencing.
- the compounds substituted with effector groups are of particular value in particular for antisense therapy.
- the OH group, amino or thiol group of a nucleoside, nucleotide or oligonucleotide located in the 3 'and / or 4' position is coupled to a spacer group, such as an aminocarboxylic acid, carboxylic acid or a peptide, and then a reporter or effector molecule attached.
- a spacer group such as an aminocarboxylic acid, carboxylic acid or a peptide
- the resulting 3'- or 4'-hydroxyl-, amino- or TT ⁇ iol-modified nucleosides, nucleotides and oligonucleotides can then be used for the synthesis of counter-strands in the presence of a natural or synthetic template strand as well as for the detection of certain sequences or the localization of a Effector molecule to be used at certain sequences in genetic material.
- Another object of the invention is a method for producing the 3 * - (4 '-) modified nucleosides or nucleotides according to the general formula (1).
- Base Carrier I ((LLiirnker) -X
- Base purine, pyrimidine base or desazapurins or their derivatives, n: 0 or 1
- nucleoside derivative is cleaved from the support matrix and, if appropriate, the 5'- Position.
- the conversion to nucleosides bound to a solid support via a linker in the 5 '- (6' -) position can moreover be carried out by other methods known to the person skilled in the art.
- All selectively cleavable anchor groups can be used as the linker group [z. BGB Fields and RL Noble, Int. J. Peptide Prot. Res. 35: 165-171 (1990)].
- Groupings which can be cleaved under mild conditions, such as, for example, photochemically, by hydrogenation or in the acidic or alkaline range, have proven particularly suitable proven.
- Preferred linker groups are trityl groups, which may be substituted. Methoxy and halogen radicals are suitable substituents here.
- Dimethoxy and o-chlorotrityl groups have proven to be particularly suitable here.
- the basic procedure for linking the linker grapple with the 5 'or 6' position of nucleosides is known to the person skilled in the art (MJ Gait: "Oligonucleotide synthesis; a practical approach”; IRL Press, Oxford, Washington DC (1984 ), P. 12 ff).
- any solid, chemically inert material which is insoluble in the solvent used in each case and which should be as easy to filter as possible is suitable as the support material according to the invention.
- Preferred carrier materials are inorganic, polymeric materials (resins) based on polystyrene or polyethylene glycol.
- nucleosides bound to solid supports are then mixed with a corresponding carboxylic acid, aminocarboxylic acid or peptide derivative in the presence of an activation reagent, such as, for example, condensing agents such as DCC, DIC or HOBT.
- an activation reagent such as, for example, condensing agents such as DCC, DIC or HOBT.
- one or more identical or different reporter Zeffector molecules are introduced covalently selectively in the side chain or C or N-te ⁇ ninal, for example via esterification, amidation, sulfonamidation, sulfonic acid esterification or by reaction with isothiocyanates or N-hydroxysuccinimide esters.
- Appropriate methods are known to the person skilled in the art.
- the nucleoside derivatives are preferably cleaved from the linker group under weakly acidic, basic, photochemical or reductive conditions.
- Nucleoside derivatives which have one or more protective groups or side chains on the spacer group can be prepared accordingly.
- the nucleoside derivatives prepared in this way can then be converted into the corresponding 5'- or 6'-mono-, di- or triphosphates (nucleotides), alkylphosphonates, dialkylphosphinates or phosphoramidite by methods known to those skilled in the art.
- the synthesis of the 5'- or 6'-modified nucleosides according to the invention is particularly advantageous because, unlike in known processes, a large excess of the dye component can be used without problems and can be easily separated off. For the previously known processes, lengthy and expensive chromatographic purification steps follow the actual production process for separating the unreacted dye.
- the compounds of the general formula (1) according to the invention can advantageously be used as substrates for DNA / RNA polymerases by means of a primer and a template strand and in the presence of the four nucleoside triphosphates.
- Suitable polymerases here are T7, Taq polymerase, DNA polymerase I and reverse transcriptases.
- the compounds are also suitable as terminators in enzymatic DNA RNA sequencing.
- the termination of the synthesis can in each case be determined specifically by using a 3 '- (4' -) modified A, C, G, T nucleotide of the formula (1). This is of particular importance for the synthesis of DNA counter-strands in the presence of a template strand (and thus also for the sequencing of DNA strands), since the use of a modified nucleotide ensures a very base-specific termination of the reaction.
- RNA nucleosides and oligonucleotides takes place in an analogous manner.
- the derivatizable oligonucleotides can be synthesized using a start nucleotide which has a spacer group at the 3 '- (4') end and has been amino- or thiovariated and fixed to a polymeric support.
- All DNA and RNA nucleotides produced in the conventional sense are considered oligonucleotides, but preferably in a length of 2 to 100, particularly preferably 12 - 50 nucleotides (chemical synthesis) or in a length of up to approx. 3,000 nucleotides (enzymatic synthesis), depending on the efficiency of the used
- the oligonucleotide synthesis takes place, starting from the starting nucleotide-carrier complex, in the conventional sense, i. H. in the 3 'and 5' direction and enables the synthesis of an oligonucleotide of a defined sequence.
- the start nucleoside is fixed to commercially available carriers via a connecting arm (spacer) which can be cleaved after synthesis; for example via the succinic acid linkage known from the literature or else via a linkage with urethane (Efimov et al, Nucl. Acids. Res. 11, 8369, 1983).
- the oligonucleotide After synthesis has taken place, the oligonucleotide must be cleaved from the support using suitable reagents. The derivatization with any fluorescent dye takes place immediately afterwards.
- the reverse synthesis direction (5 1 -. 3 ') of oligonucleotides is also possible in that the starting nucleoside is linked to the linker grouping of the support material via the 5'-OH group and the procedure is analogous to conventional oligonucleotide synthesis.
- the dye labeling of the oligonucleotide can take place on the solid phase.
- oligonucleotides thus synthesized and modified at the 3 '(4') end can then be used for the detection of e.g. B. complementary oligonucleotides or nucleic acids and corresponding derivatives can be used.
- the compounds according to the invention are also suitable as in vivo and in vitro sensors in analysis and as gene probes in gene therapy and for related analytical purposes.
- Example 1 The following examples further illustrate the invention: Example 1:
- the coated resin is filtered off and washed several times with DMF, DCM, isopropanol and finally with diethyl ether. After drying in an oil pump vacuum, the amino acid loading is determined using the quantitative ninhydrin test (Example 7b) or by UV spectrometric determination of the Fmoc elimination. By varying the amount of amino acid, amino acid loads between 0.05 and 1.1 mmol / g are obtained.
- Orthogonality of the protective groups also allows the introduction of one or more identical or different fluorescent dyes selectively into the side chain or N-terminal.
- the introduction of fluorescent dyes into the side chain of trift-functional amino acids proceeds analogously to the N ⁇ coupling, but the proportion of DMAP must be increased.
- the ester cleavage is carried out under weakly acidic conditions. Approx. 20 ml of a mixture of glacial acetic acid / TFE / DCM in a ratio of (v / v / v 1: 2: 7) [K. Barlos, O. Chatzi, D. Gatos, G. Stauropoulos, Int. J. Peptide Prot. Res. 37, (1991), 513-520].
- the cleavage time is usually approximately 90 minutes. If no His (N TM 1 Trt) residue is contained, it can be split off with a mixture of DCM / TFE (v / v 1: 1).
- the resin is then filtered off and the peptide solution is made up with about 100 ml of water. The added water prevents the acetic acid from concentrating when the volatile components are subsequently distilled off on a rotary evaporator.
- the hydrophobic amino acid and peptide derivatives are precipitated on spinning in and are now dried in the freeze dryer.
- the resin loading is carried out with the quantitative ninhydrin test, in the case of the 3'-amino nucleotides (example 7b), by UV spectrometric determination after suitable derivatization of the 3'-functionality of the nucleoside or by weighing the resin certainly.
- the amount of nucleosides resin loads between 0.1 and 1 mmol g are obtained.
- the ether cleavage is carried out under acidic conditions. About 1 ml of a solution of dichloroacetic acid / DCM in a ratio of (v / v 3:97) is used per 1 g of loaded resin. The split-off time is approx. 1 min. The resin is then filtered off and the product solution is immediately neutralized with an equimolar solution of DIEA DCM in the ratio (v / v 63: 937). The resin is washed several times with a little ACN. About 10 ml of water are added. The product is now dried in the freeze dryer.

- Solution 2 A 2% solution of 33 mg potassium cyanide KCN in 50 ml water in pyridine.
- Solution 3 A solution of 500 mg ninhydrin in 10 ml ethanol

- Example 17 compound 9 was built up successively on the support (1. coating of the resin with thymidine, 2. coupling of a (Fmoc) amino acid, 3. deprotection of the amino acid, 4. coupling of the dye).
- Triphosphate synthesis was carried out according to [Ludwig, Eckstein, J. Org. Chem. 54,
- the carrier resin was cleaved off and the 5'-triphosphate was obtained after phosphorylation.
- each mix also contains: 1 mM dATP, 1 mM dGTP, 1 mM dCTP, 1 mM dTTP, 50 mM NaCl, 40 mM Tris • HC1, pH 7.5) pipetted into four reaction vessels and at least 1 minute at approx. 37 ° C warmed up. Then 3.8 ⁇ l of the first mix (annealing mix) are pipetted into the preheated termination mixes.
- a stop reagent deionized formamide solution, dextran blue
- the reaction solutions are heated for 2 minutes at about 90 ° C and to a 6% denaturing Sequence gel added to the individual pockets (a 6 ⁇ l). The individual DNA fragments were then detected and identified using a fluorescence detection device.
