Description
分子質量(分子量)は、サイズ排除クロマトグラフィー(欧州薬局方4版:クロマトグラフィー技術に関しては2.2.30項および2.2.46項、方法に関しては01/2002:0828、1297頁)によって決定した。
Mwが13,000DaであるヘパリンNa塩の10%溶液5lを、貯蔵タンク、ランプ4個(合計460W)の循環回路、液を循環回路中へ循環させる蠕動ポンプ(19L/h)、および溶液を30℃に冷却する小型熱交換器で形成される照射システムに導入する。
液を16時間照射する。
ヘパリンを回収し、噴霧乾燥し、分析する。
Mw=5.000
260nmにおける吸光度(0.4%溶液)=0.080
無機硫酸塩=なし
aXa活性=106U/mg
抗凝固活性=114U/mg
NMR:13C-NMRシグナルの積分によって得た値
カットオフ値が5.000Daの膜による液の連続ろ過を行いながら、実施例1を繰り返した。膜ろ過によって取り出した液は、出発原料の10%ヘパリンNa塩溶液を加えて連続的に補った。
10%へパリン溶液に代えて5%デルマタン硫酸(Mw=35,000Da)溶液を使用して、実施例1を繰り返した。
照射後、回収されたデルマタン硫酸は以下のような特徴を有していた。
Mw=15.000Da
260nmにおける吸光度=0.150
無機硫酸塩=なし
得られた中間的に解重合されたデルマタン硫酸は、ゲル浸透クロマトグラフィーによって分別することができる。所望の分子量を含む画分を集め、限外ろ過によって濃縮し、凍結乾燥する。
Mwが14,238DaであるヘパリンNa塩の10%溶液2.5lを、貯蔵タンク、115Wのランプ1個を収容した循環回路、液を循環回路中へ循環させる蠕動ポンプ(25L/h)、および溶液を30℃に冷却する小型熱交換器で形成される照射システムに導入した。
溶液を36時間照射し、Mw量測定のため試料を採取した。
実施例4を56℃で繰り返した。
表1に、30℃および56℃で得られた結果を報告する。
