Definitions
- the present invention relates to a silyl linker that can be efficiently introduced into a solid support used for DNA synthesis.
- Non-Patent Document 1 (Non-Patent Document 1).
- this requires a long time, almost one day, to introduce the compound into the solid phase carrier, and its introduction efficiency is particularly low when introducing the compound into an HCP solid phase (34 mol / g) with a small total amount of amino groups. It was extremely low (6-8 mol / g), which was not sufficient in terms of practicality.
- Non-Patent Document 1 Kobori, A .; Miyata, K .; Ushioda, ⁇ .; Seio, ⁇ .; Sekine, ⁇ ., Chemistry
- an object of the present invention is to develop a silyl linker that can be efficiently introduced into a solid support.
- the inventor has solved this problem by introducing a spacer to the conventional silyl linker, and has completed the present invention.
- the present invention provides a compound represented by the following general formula (I) or a salt thereof or a silyl linker for solid phase synthesis of a nucleic acid:
- Rl and R2 are an alkyl group or an aryl group, and (A) represents a part of the spacer. Show)
- the present invention provides a compound as described above, wherein the compound is a nucleoside or a derivative thereof (for example, a compound in which the 5-position hydroxyl group of the sugar is protected with an appropriate protecting group) via an oxygen atom at the 3-position of the sugar. It relates to a 3'-terminal nucleoside unit formed by bonding.
- the base constituting the nucleoside is thymine, there is no amino group, which is advantageous because it does not need to be protected when introduced into a solid phase.
- the present invention also relates to any solid phase carrier known to those skilled in the art into which the 3'-terminal nucleoside unit or the silyl linker for nucleic acid solid phase synthesis has been introduced, particularly an HCP solid phase carrier.
- the present invention also relates to a method for synthesizing a nucleic acid oligomer using the solid phase carrier of the present invention. This method is particularly advantageous for the synthesis of a nucleic acid oligomer containing a modified base which is unstable under basic conditions such as acetylsilyl cytosine.
- novel silyl linker of the present invention can be cut out under neutral conditions, and the amount of the 3 'terminal nucleoside unit introduced into the solid support is 20-30 ⁇ mol / It could be improved to about g.
- FIG. 1 shows the FIG. 1 reversed-phase 'anion exchange HPLC chart of d synthesized using Shirirurinka one [GC ae ATCAGC ae C ae TCAT ].
- n represents a natural number, preferably 2-18). It is also possible for the alkylene group to have at least one other group, for example an ether linkage or a thioether linkage.
- R1 and R2 which are arbitrary substituents known to those skilled in the art, may be present on a silyl group.
- a silyl group For example, an alkyl group having 1 to 5 carbon atoms, or a benzyl group, a phenyl group, And aryl groups such as a naphthyl group.
- the benzene ring skeleton of the compound of the present invention may have any substituent known to those skilled in the art.
- the powerful substituent include an alkyl group having 114 carbon atoms, a halogeno group, a nitro group, a cyano group, and a methoxy group.
- -CONH- and Si are bonded to the benzene ring skeleton at the para position.
- any known salts or esters can be selected, for example, triethylammonium salt, tributylammonium salt, and ethyldiisopropylammonium.
- salts such as salts, and esters such as cyanoethyl ester, aryl ester, and 4-trophenyl-ethyl ester.
- the compound of the present invention can be easily synthesized by those skilled in the art by referring to the present specification, particularly, the descriptions in the following Examples and the like. Further, V and various conditions not described in this specification can be appropriately selected by those skilled in the art.
- the resultant was diluted with black-mouthed form (100 mL), and extracted three times with 100% of a 5 wt% -sodium bicarbonate aqueous solution. Further, the organic layer was recovered, dried over anhydrous sodium sulfate, and filtered, and the solvent was distilled off under reduced pressure. The crude product was purified by silica gel column chromatography (1% pyridine), eluted with hexane using a gradient of 30-100% chloroform, and the solvent was distilled off. Then, it was dissolved in 30 mL of acetonitrile, DBU (1.7 mL, 11.2 mmol) was added thereto, and the mixture was stirred at room temperature for 30 minutes.
- DBU 1.7 mL, 11.2 mmol
- the solid support was filtered, washed and dried with acetonitrile, and then added to a solution of acetic anhydride (0.5 ml) and DMAP (5 mg) dissolved in pyridin (4.5 mL). After stirring for 3 hours, the solid support was filtered again and washed with acetonitrile. The amount introduced into the solid support was determined by colorimetric determination of trityl groups (21 / z mol / g
- the cyanoethyl group was removed with CN (500 ⁇ L). Wash the solid support with CH CN (1 mL x 3).
- the solid support was treated for 1 hour with a reaction solution of TBAF (131 mg, 0.5 mmol) and acetic acid (24 ⁇ L, 0.5 mmol) dissolved in 500 ⁇ l of anhydrous THF to cut out DNA oligomers.
- the resulting mixed solution was desalted using an S-mark-Pak C18 cartridge, further diluted with water, and analyzed using reverse phase / anion exchange HPLC.
- the results obtained in the mass spectrometry of the compound are as follows: d [GC ac ATCAGC ac C ac TCAT], Mass (M- H) calcd 4017.72, found 4018.00.
- silyl linker or the 3 ′ terminal nucleoside unit of the present invention it becomes possible to synthesize a DNA derivative having a basic and unstable functional group having various functions.
