Regarding insufficient deprotection, it was speculated that deprotection would be completed without problems if the deprotection time was extended.
- Example 4 Synthesis of single-stranded polynucleotides 2 According to the scheme of Example 3, using the amidite monomer (Pac 2 D-SNA amidite monomer, Compound 6) synthesized in Example 1 and the amidite monomer (4-AcetoxybenzylsU-SNA amidite monomer, Compound 15) synthesized in Example 2, an SNA polynucleotide containing 2,6-diaminopurine (D) and 2-thiouracil (sU) as bases (base sequence: (S)-CDD CDsU CD G TCsU G DsU DDG CTA-(R) (SEQ ID NO: 1)) was synthesized on a solid-phase synthesizer by the phosphoramidite method.
- Phenoxyacetic anhydride was used instead of Acetic anhydride. After synthesis, it was cut out and deprotected at NH 3 aq (containing 50 mM sodium hydrogen sulfide) at 55°C for 3 h.
- FIG. 2 shows a MALDI-TOF-MS chart of the crude product (before HPLC purification in the scheme of Example 3). A high intensity peak (including ion coordination) for the desired sequence ([M+H] + ) was observed.
- an SNA polynucleotide containing 2,6-diaminopurine (D) as a base was synthesized by the phosphoramidite method in the same manner as in Example 3 using a solid-phase synthesizer. After synthesis, cleavage and deprotection treatment were performed at NH 3 aq at 55°C. At this time, the reaction was carried out for a long time (about 10 hours). When the crude product was subjected to MS analysis, a strong peak was observed indicating that the deprotection was an impurity or a peak presumed to be a reaction intermediate. If the reaction is carried out for a longer period of time, the hydrolysis of the SNA skeleton proceeds and the yield decreases.
- D 2,6-diaminopurine
- reaction conditions 1 3-Bromopropionitrile, Et3N , DMF 2: 3-Bromopropionitrile, NaH, DMF 3: 3 - Bromopropionitrile, K2CO3DMF 4: 3-Bromopropionitrile, KOH, H2O /EtOH (1:1)
- Pac 2 DL-aTNA amidite monomer was obtained as a white solid, 1.65 g (1.56 mmol), 57% yield.
- Example 2 The above compound (4-AcetoxybenzylsU-L-aTNA amidite monomer) was synthesized in the same manner as compound 15 (4-AcetoxybenzylsU-SNA amidite monomer) in Example 2. Specifically, it was synthesized in the same manner as in Example 2, except that L-aTNA was used in place of SNA in (2) of Example 2-7.
- Example 7 Synthesis of single-stranded polynucleotides 3 According to the scheme of Example 3, using the amidite monomer (Pac 2 DL-aTNA amidite monomer) synthesized in Example 5 and the amidite monomer (4-AcetoxybenzylsU-L-aTNA amidite monomer) synthesized in Example 6, an L-aTNA polynucleotide containing 2,6-diaminopurine (D) and 2-thiouracil (sU) as bases was synthesized by a phosphoramidite method using a solid-phase synthesizer. . As a capping reagent, Phenoxyacetic anhydride was used instead of Acetic anhydride. After synthesis, it was cut out and deprotected at NH 3 aq (containing 50 mM sodium hydrogen sulfide) at 55°C for 3 h.
