Abstract
Description
式中、R1およびR2はHであり、R1およびR2はホスホジエステル結合となることができ、Baseは核酸塩基となることができ、R3は以下に記載する官能基である。
UNA−A末端の形:破線の結合はプロパン−3−イル結合を示す。
したがって、末端UNAモノマーを有するUNAオリゴマーは、siRNAのような通常の核酸剤とは構造上顕著に異なるものである。例えば、siRNAは、二本鎖中の末端モノマーまたはオーバーハングが安定化されていることを必要とする場合がある。それに対して、末端UNAモノマーのなじみ性は、異なる特性を有するUNAオリゴマーを提供することができる。
は、第1鎖上のUNAモノマー 1−端、第1鎖上のUNAモノマー 3−端、第2鎖上のUNAモノマー 3−端、および第2鎖上のヌクレオチド 5’−端を有する。
本実施例は、UNAオリゴマーがRNA干渉による遺伝子サイレンシングにおいてパッセンジャー鎖のoff-target活性を劇的に低下させることを示す。パッセンジャー鎖off-target活性の低下は、オリゴマー中の種々のUNAモノマーのポジショニングに依存することができる。本実施例において、UNAオリゴマー中の3つのポジションのUNAモノマーの組合せの存在、より詳細には、5'端および3'端のパッセンジャー鎖中、ならびに3'端のガイド鎖中のUNAモノマーの組合せの存在が、パッセンジャー鎖によるoff-targetノックダウン活性を大きく低下したことを示す。
