Description
以下の式(5)、(6)及び(7)からなる群から選択されるいずれかの反応を含む、製造方法。
(2)式(5)〜式(7)中、R10及びR11は、R10及びR11が一体となった環状アセタール基を表す、(1)に記載の製造方法。
(3)前記式(5)の反応に引き続き、以下の式(5)’の反応を含む、(1)又は(2)に記載の方法。
以下の式(1)又は(2)で表される、ヌクレオシド誘導体又はその塩を用いてオリゴヌクレオチド誘導体を製造する方法であって、
以下の式(5)、(6)及び(7)からなる群から選択されるいずれかの反応を含む、製造方法。
(2)本ヌクレオシド誘導体は、RNAを用いた検出プローブなど試薬としても有用である。すなわち、種々のRNA試薬に好適なオリゴヌクレオチドを提供できる。
(3)本明細書に開示されるヌクレオシド誘導体は、従来困難であったリボースの第4’位に種々のアミノアルキル系置換基を導入し、その性質について精査したところ、予想を超える有用な特徴を見出したことに基づいている。従来、リボヌクレアーゼ耐性に関しては、リボースの2’位や3’位の置換体によることが一般的であった。本明細書に開示されるヌクレオシド誘導体によれば、予想を超えるリボヌクレアーゼ耐性と細胞膜透過性という、RNA医薬等に有用な特性を兼ね備えることができる。以下、本明細書の開示の各種実施形態について詳細に説明する。
本ヌクレオシド誘導体は、以下の式(1)又は(2)で表されるヌクレオシド誘導体又はその塩とすることができる。本ヌクレオシド誘導体は、当業者の周知の方法で、オリゴヌクレオチドの部分構造に含めることができる。
本ヌクレオシド誘導体又はその塩の一つの態様は、以下の式(1)で表されるヌクレオシド誘導体又はその塩である。
式(1)中、R1は、水素原子、水酸基、水素原子がアルキル基又はアルケニル基で置換された水酸基又は保護された水酸基を表す。R1が水素原子のとき、本ヌクレオシド誘導体は、デオキシリボヌクレオシド誘導体である。R1が、水酸基、水素原子がアルキル基又はアルケニル基で置換された水酸基又は保護された水酸基であるとき、本ヌクレオシド誘導体は、リボヌクレオシド誘導体である。
式(2)中、Xは、ハロゲン原子を表す。ハロゲン原子としては、特に限定するものではないが、塩素原子、ヨウ素原子、フッ素原子及び臭素原子等が挙げられる。R1がハロゲン原子のとき、本ヌクレオシド誘導体は、デオキシリボヌクレオシド誘導体である。なお、ハロゲン原子は、式(2)からも明らかなように、リボースの2’位の炭素原子に対する結合方向は特に限定するものではないが、天然のリボースの水酸基に相当するようにハロゲン原子が結合することが好適である。
本明細書中、アルキル基としては、直鎖状、分枝状、環状、又はそれらの組み合わせである飽和炭化水素基が挙げられる。通常は、低級アルキル基が好ましく、例えば炭素数1〜6個の低級アルキル基、又は炭素数1〜5個の低級アルキル基がより好ましい例として挙げられ、さらに炭素数1〜4個又は炭素数1〜3個の低級アルキル基が特に好ましい例として挙げられる。直鎖状の炭素数1から4までのアルキル基としては、メチル基、エチル基、n−プロピル基、又n−ブチル基等が好適な例として挙げられ、このうち、メチル基、エチル基、n−プロピル基が好ましく、また例えばメチル基、エチル基が好ましく、また例えばメチル基が好ましい。また分枝状の炭素数1から4までのアルキル基としては、イソプロピル基、イソブチル基、s−ブチル基、t−ブチル基等が挙げられ、このうち、イソプロピル基が特に好ましい例として挙げられる。又、環状の炭素数1から4までのアルキル基としては、シクロプロピル基、シクロブチル基、又はシクロプロピルメチル基等が挙げられる。
本明細書中、アルケニル基としては、直鎖状、分枝状、環状、又はそれらの組み合わせである飽和炭化水素基が挙げられる。通常は、低級アルケニル基が好ましく、低級アルケニル基としては、例えばエテニル基、1−プロペニル基、2−プロペニル基、1−メチル−2−プロペニル基、1−メチル−1−プロペニル基、2−メチル−1−プロペニル基、1−ブテニル基、2−ブテニル基などが挙げられる。
本明細書において、水酸基の保護基としては、当業者に周知であって、例えばProtective Groups in Organic Synthesis(John Wiley and Sons、2007年版)を参考にすることができる。水酸基の保護基としては、代表的な例を挙げると、例えば、脂肪族アシル基、芳香族アシル基、低級アルコキシメチル基、適宜の置換基があってもよいオキシカルボニル基、適宜の置換基があってもよいテトラヒドロピラニル基、適宜の置換基があってもよいテトラチオピラニル基、合わせて1から3個の置換又は無置換のアリール基にて置換されたメチル基(但し前述の置換アリールにおける置換基としては、低級アルキル、低級アルコキシ、ハロゲン原子、又はシアノ基を意味する。)、又はシリル基、等が例示される。
式(1)及び式(2)中、R2及びR4は、互いに同一又は異なっていてもよく、水素原子、水酸基の保護基、リン酸基、保護されたリン酸基、又は−P(=O)n(R5)R6を表す。水酸基の保護基は既に説明したとおりである。
