Definitions
- the present invention relates to a monomer and an oligomer of a crosslinked nucleic acid GuNA, a method for producing the same, and an intermediate compound for the production thereof.
- an antisense method an anti-gene method, a method using an aptamer, a method using siRNA, etc. as a method for treating a disease with a nucleic acid drug.
- the antisense method introduces an oligonucleotide (antisense strand) complementary to the mRNA involved in the disease from the outside to form a double strand, thereby inhibiting the translation process of the pathogenic RNA and treating the disease.
- the method using siRNA is also similar to the antisense method, in which translation from mRNA to protein is inhibited by double-stranded RNA administered to a living body.
- the antigene method suppresses transcription from DNA to RNA by introducing from the outside a triplex-forming oligonucleotide corresponding to a DNA site that transcribes pathogenic RNA.
- aptamers exhibit functions by regulating the activity of the protein by specifically binding to biological components such as proteins that cause disease.
- S-oligo phosphorothioate type oligonucleotide
- BNA bridged nucleic acid
- LNA 4′-locked nucleic acid
- 2'-amino LNA has been reported as one of artificial nucleic acids (Non-patent Document 7). It has nuclease resistance, has high binding affinity with the target nucleic acid chain, and is the most expected molecule as a nucleic acid drug material like the LNA. However, only nucleotides having thyminyl or 5-methyl-cytosinyl are known as nucleosides having appropriate substituents that can be used as raw materials for synthesizing oligonucleotides (Non-patent Document 8). In addition, Aza-ENA has been reported as another artificial nucleic acid (Non-patent Document 9). It has a structure in which the carbon atom constituting the bridge is one more than that of 2′-amino LNA, and only thyminyl is known as the base moiety of the nucleic acid.
- Still another artificial nucleic acid is guanidine cross-linked artificial nucleic acid (GuNA).
- GuNA guanidine cross-linked artificial nucleic acid
- Patent Document 5 GuNA containing thyminyl as a nucleobase moiety is known.
- the production of GuNA requires multiple steps, and therefore it has not been easy to produce it efficiently.
- GENA has been reported as an artificial nucleic acid similar to GuNA (Non-patent Document 10). The number of carbon atoms constituting the bridge is one more than that of GuNA, and only the base portion of the nucleic acid is known as thyminyl.
- Non-Patent Document 11 A known method for producing GuNA is described in Non-Patent Document 11, but it requires a multi-step number of steps, and the yield of GuNA production is not sufficient.
- the manufacturing route is shown below.
- the present invention relates to a method for producing a guanidine cross-linked artificial nucleic acid (hereinafter abbreviated as GuNA), an intermediate compound for the production, and a GuNA monomer or oligomer.

主要製造経路([A法])において、出発物質として糖化合物1を用い、R1基として水酸基保護基を導入して化合物2を調製する。次いで、化合物2を出発として用いて、公知の反応に従って多段階(6工程)の反応経路を経て、一般式IIIで表される化合物の前駆体(例えば、化合物7)を調製する。当該化合物を脱保護することにより、一般式IIIで表される化合物(例えば、化合物8)を新規な中間体として得る。続いて、適当なアジド化試薬を用いて光延反応を行うことにより、一般式IIで表される化合物(例えば、化合物9(チミン誘導体)、化合物36(ウラシル誘導体))を新規な中間体として得る。
一般式IIIで表される新規な中間体化合物の前駆体の製造
まず、出発原料の化合物1から、一般式IIIの化合物の前駆体(例えば、化合物7)は文献公知の方法(例えば、J. Org. Chem. 2011, 76, 9891-9899に記載)に従って7工程を経て行う。
代表的な製造例を下記に示す。
各製造工程は、J. Org. Chem. 2011, 76, 9891-9899に記載の方法に従う反応条件下で行うことができるが、出発原料である化合物1の種類に応じて個々の反応工程の条件(例えば、試薬、反応時間等)を適宜改変してもよい。また、J. Org. Chem. 2011, 76, 9891-9899に記載の方法によれば、中間体化合物4に対して核酸塩基としてチミン(T)を反応させるのに対して、下記に示す通り、チミン(T)に代わって別の核酸塩基(例えば、ウラシル(U))と反応させることによって、チミン以外の各種核酸塩基の類縁体を製造することもできる。
次いで、前記の調製した一般式III化合物の前駆体を適当な溶媒中、脱保護反応により、新規な一般式IIIで表される中間体化合物(例えば、化合物8(チミン)、化合物34(ウラシル))を得る。かかる脱保護反応は、保護基の種類に応じて適当な反応条件(例えば、試薬等)下で行うことができる。例えば、水酸基の保護基Raがシリル型保護基(例えば、TBDPS)であるときは、酸性条件下での加水分解(例えば、酢酸-THF-水)またはフッ化物イオン供与試薬(例えば、TBAF)を用いて処理することにより、実施することができる。
溶媒としては反応に影響を与えないものであればよく、適当な溶媒(例えば、THF等のエーテル類、ジクロロメタン等のハロゲン化炭化水素類、水またはそれらの混合溶媒等)中、実施することができる。反応温度は、0℃~100℃、とりわけ0℃~50℃で好適に進行する。
かかるアジド化反応は、一般式IIIで表される化合物を光延反応条件下(例えば、アジド化試薬(例えば、ジフェニルホスホリルアジド(DPPA)を、アゾジカルボン酸ジエステル(例えば、アゾジカルボン酸ジエチル(DEAD)、アゾジカルボン酸ジイソプロピル(DIAD))、およびトリフェニルホスフィン(Ph3P)の存在下で行う)で実施することができる。
溶媒としては反応に影響を与えないものであればよく、適当な溶媒(例えば、THF等のエーテル類、ジクロロメタン等のハロゲン化炭化水素類、トルエンなどの炭化系水素類、水またはそれらの混合溶媒等)中、実施することができる。反応温度は、-78℃~100℃、とりわけ0℃~50℃で好適に進行する。
脱離基Xとしては、有機合成上一般的に知られる基であれば特に限定されるものではないが、例えばメタンスルホニルオキシ基(メシルオキシ;Ms-O-)、トリフルオロメタンスルホニルオキシ基、p-トルエンスルホニルオキシ基を挙げられ、メシルオキシ基が好ましい。脱離基を導入するための試薬の例としては、トリフルオロメタンスルホニルクロリド、メタンスルホニルクロリド、p-トルエンスルホニルクロリドまたはトリフルオロメタンスルホン酸無水物が挙げられ、メタンスルホニルクロリドが好ましい。
アジド化剤の例としては、nBu4NN3またはアジ化ナトリウムが挙げられる。
溶媒としては反応に影響を与えないものであればよく、適当な溶媒(例えば、THF等のエーテル類、ジクロロメタン等のハロゲン化炭化水素類、水またはそれらの混合溶媒等)中、実施することができる。反応温度は、-25℃~室温、とりわけ0℃~室温で好適に進行する。
一方、脱保護およびアジド化を伴う反応は、有機合成化学(例えば、糖合成)でよく知られる反応条件下、脱離基の種類に応じて適当なアジド化試薬(例えば、テトラブチルアンモニウムアジド)を実施することができる。
溶媒としては反応に影響を与えないものであればよく、適当な溶媒(例えば、ジオキサン等のエーテル類、ジクロロメタン等のハロゲン化炭化水素類、水またはそれらの混合溶媒等)中、実施することができる。反応温度は、室温から溶媒還流下の温度、例えば100℃以上の温度で好適に進行する。
a)一般式IIIの化合物の前駆体を脱保護して(5’位の水酸基保護基の脱保護)、一般式IIIで表される化合物を得る;および、
b)得られた一般式IIIで表される化合物を適当なアジド化試薬を用いる光延反応に付して、一般式IIで表される化合物を得る。
別製法として、前記b)工程に代えて、以下のb')およびc')工程を含んでもよい:
b')得られた一般式IIIで表される化合物を適当な試薬と反応させて、脱離基(X)を導入して(5’位の水酸基上)、一般式IVで表される化合物を得る;
c')得られた一般式IVで表される化合物を適当なアジド化試薬と反応させて、一般式IIで表される化合物を得る。
一般式IIで表される化合物の別製造方法を記載する。
メシル化反応は、有機合成化学(例えば、核酸合成)で一般的に知られる反応条件下(例えば、適当な水酸基の活性化剤(例えば、メタンスルホニルクロリド、メタンスルホン酸無水物などのメシル化剤)を塩基条件下(例えば、トリエチルアミンの存在下)、実施することができる。
溶媒としては反応に影響を与えないものであればよく、適当な溶媒(例えば、THF等のエーテル類、ジクロロメタン等のハロゲン化炭化水素類、水またはそれらの混合溶媒等)中、実施することができる。反応温度は、-25℃~100℃、とりわけ0℃~室温で好適に進行する。
新規な中間体としての一般式Vで表される化合物に、水酸基の活性化剤(例えば、トリフルオロメタンスルホニル化剤)を反応させて、一般式V中のテトラヒドロフラン環に置換している無保護の水酸基を活性化することによって、一般式IVで表される化合物を得る。
一般式IIで表される化合物の更に別の製造方法を記載する。
次いで、一般式VIで表される中間体化合物を、前記の製法における化合物6から化合物7(または、化合物25から化合物10)を得る方法と同様の反応条件下、水酸基の活性化剤を塩基性条件下(例えば、DMAP存在下)反応させることにより、一般式IIで表される新規な中間体化合物(具体例としては、化合物9)を製造する。

表1:グアニジン架橋型核酸を有するオリゴヌクレオチド
実施例70で得られた各種オリゴヌクレオチド(化合物48から66)と相補鎖オリゴヌクレオチド(化合物67から74、または化合物75から78)とアニーリング処理して二重鎖を形成させた後、二重鎖の50%が乖離する温度であるTm値を測定することにより、オリゴヌクレオチドの二重鎖形成能を調べた。
具体的には,塩化ナトリウム 100mM、リン酸ナトリウム緩衝液(pH6.99) 10mM、オリゴヌクレオチド 4μM、相補鎖 4μMを含むサンプル溶液(130μL)を、表2に記載の化合物については、室温から毎分5℃で95℃まで昇温した後、毎分0.5℃の速度で降温し5℃まで冷却し、表3に記載の化合物については沸騰水浴で加熱した後、静置し室温まで冷却した。分光光度計(Shimadzu,UV-1650PCまたはUV-1800)のセル室内に結露防止のため窒素気流を通し、サンプル溶液を5℃まで徐々に冷却し、さらに1分間5℃に保った後、測定を開始した。90℃まで毎分0.5℃の割合で温度を緩やかに上昇させ、0.5℃上昇する毎に260 nmにおける紫外部吸収を測定した。なお、温度上昇による濃度変化を防止するため、セルは蓋付きのものを用いた。結果をTm値および修飾単位あたりのTm値差にて表2に示す。Tm値が高いほど、二重鎖形成能が高いことを示す。
・化合物51,59の相補鎖: DNA/5’-d(AGCAAAAAACGC)-3’(化合物67)(配列番号12),
RNA/5’-r(AGCAAAAAACGC)-3’(化合物75)(配列番号13),
・化合物52,60の相補鎖: DNA/5’-d(AGCAAATAACGC)-3’(化合物68)(配列番号14),
RNA/5’-r(AGCAAATAACGC)-3’(化合物76)(配列番号15),
・化合物53,61の相補鎖: DNA/5’-d(AGCAAAGAACGC)-3’(化合物69)(配列番号16),
RNA/5’-r(AGCAAAGAACGC)-3’(化合物77)(配列番号17),
・化合物54,62の相補鎖: DNA/5’-d(AGCAAACAACGC)-3’(化合物70)(配列番号18),
RNA/5’-r(AGCAAACAACGC)-3’(化合物78)(配列番号19)。
配列番号13、15、17、および19は、RNAオリゴヌクレオチドを示す。
