Abstract
Description
(1)リン原子がボランに配位しているため、天然型のものと比較して脂溶性が高く、高い細胞膜透過性が期待できる、
(2)ヌクレアーゼに対する耐性が高い、
(3)標的mRNAに対する選択性が高い、
(4)ボラノホスフェートDNAとRNAが形成する二重鎖がRNaseHの基質となり、標的mRNAが効果的に分解される、
(5)ホウ素中性子補捉療法(BNCT)への応用が期待できる、
といった有利な特徴を持つことで知られており、実用的なアンチセンス分子として注目されてきている。
(i) 鎖を延長するたびにボラノ化を繰り返し行わなければならない、
(ii)ボラノ化試薬による核酸塩基部位への副反応
といった問題点を排除した手法、即ち、下記式で示される、予めボラノ化したモノマーを用いてオリゴヌクレオチドを合成する手法を報告してきた(日本化学会第78回年会予稿集746頁(2000年)、日本化学会第79回年会予稿集942頁(2001年)、日本化学会第81回年会予稿集937頁(2002年)、アンチセンスDNA/RNA研究会予稿集48頁(2002年)、日本化学会第83回年会予稿集944頁(2003年)、Tetrahedron Lett.43(2002)4237)。

下記式(2)で示されるボラノホスホリル化剤と、
を反応させ反応生成物を得る工程と、前記反応生成物とトリエチルアミンとを反応させる工程とを含むことを特徴とする、ボラノホスフェートモノマーの製造方法が提供される。
上記式(1)中のシアノエチル基をβ脱離させない強塩基、及び、下記式(4a)又は、下記式(4b)で示される縮合剤存在下、
下記一般式(5)で示されるヌクレオシド誘導体と
を反応させ、下記一般式(6)で示される二量体を製造する方法が提供される。
