Abstract
Description
(式中、Mはトリチル基及びその誘導体を示す。)
本発明の結晶は、次の構造式で示されるシュードウリジン保護体の結晶に関するものである。
本発明の結晶は、エステル系溶媒及び/又はアルコール系溶媒を用いて、シュードウリジン保護体を含む溶液からシュードウリジン保護体を晶析することにより調製することができる。
[実施例]
5’−O−(4,4’−ジメトキシトリチル)シュードウリジン結晶の製造
モレキュラシーブス4Aで乾燥したピリジン(36ml)でシュードウリジン(4.77g,18.3mmol)を2回共沸脱水した後、ピリジン(72ml)に懸濁した。室温撹拌下、4,4’−ジメトキシトリチルクロリド(7.45g,22mmol)を加え、すり栓で蓋をして同温度で2時間撹拌した。
5’−O−トリチルシュードウリジン結晶の製造
モレキュラシーブス4Aで乾燥したピリジン(5ml)でシュードウリジン(0.61g,2.5mmol)を2回共沸脱水した後、ピリジン(9.8ml)に懸濁した。室温撹拌下、トリチルクロリド(0.836g,3mmol)を加え、すり栓で蓋をして同温度で1日間撹拌した。
5’−O−(4−モノメトキシトリチル)シュードウリジン結晶の製造
モレキュラシーブス4Aで乾燥したピリジン(5ml)でシュードウリジン(0.61g,2.5mmol)を2回共沸脱水した後、ピリジン(9.8ml)に懸濁した。
室温撹拌下、4−メトキシトリチルクロリド(0.926g,3mmol)を加え、すり栓で蓋をして同温度で15時間撹拌した。
純度検定試験
実施例1で得た5’−O−(4,4’−ジメトキシトリチル)シュードウリジンの結晶純度を、高速液体クロマトグラフィー法にて分析した。その結果を表1に示す。なお、高速液体クロマトグラフィーは、以下の条件で行った。
流速:0.5ml/min
UV:260nm
温度:室温
水分測定試験
カールフィッシャー法(電量滴定法、気化温度130℃)により測定した結果、乾燥の程度により水分含量は変動するものの、実施例1で得た5’−O−(4,4’−ジメトキシトリチル)シュードウリジンの結晶の水分(w/w)は「1.3%(1番晶)」、「1.7%(2番晶)」であった。
安定性試験(1)
実施例1で得た5’−O−(4,4’−ジメトキシトリチル)シュードウリジンの結晶について気密容器中60℃、相対湿度30%下での残存率を高速液体クロマトグラフィーで測定し、別途調製した非晶質と比較することでその安定性を評価した。その結果を表2に示す。結晶が熱に対してより安定であることを確認した。
安定性試験(2)
実施例1で得た5’−O−(4,4’−ジメトキシトリチル)シュードウリジンの結晶についてデシケーター中25±2℃、相対湿度33%、57%、75%下での残存率を高速液体クロマトグラフィーで測定し(14日放置後測定)、別途調製した非晶質と比較することでその安定性を評価した。その結果を表3に示す。相対湿度75%下で顕著な差が生じ、結晶が湿気に対してより安定であることを確認した。
