Description
空気不含環境で固形製剤の再構成及びMTHFの注射のために、特定の技術的装置を用いて空中酸素の激しい排除[特許文献6]。
還元剤、たとえば L(+)-アスコルビン酸又はその塩, 還元された γ-グルタチオン, β-メルカプトエタノール, チオグリセリン, N-アセチル-L-システイン等々を、感受性の高いMTHF及び特にTHFに対する酸化防止剤として添加。
シクロデキストリン包含化合物による安定化: 特許文献1。有効成分の高い濃度を使用する。
5-ホルミルテトラヒドロ葉酸を含有する溶液をクエン酸ナトリウム, 酢酸ナトリウム又は塩化ナトリウムの添加によって安定化:特許文献2。
5-ホルミルテトラヒドロ葉酸のナトリウム塩又はカリウム塩を含有する注射溶液をpH7.5 〜 8.5で安定化: 特許文献3。
クエン酸ナトリウムの添加によって 5-ホルミルテトラヒドロ葉酸のカルシウム塩を有する溶液を安定化:特許文献4 。
したがって、 今までMTHFの安定な医薬調合物は全く示めされなかった。
したがって,還元剤(酸化防止剤)を添加しなくても、そして空気中の酸素を排除しなくても,MTHF溶液は何時間も安定である。これは、MTHFの安定な調合物がシトラートに代えてアセテート,オキザラート,マレアート及びその他の酸のパートナーを用いて得ることができないだけになおさら驚きである。これはシトラートを用いて得られるのと同等の効果がアセテートを用いて得ることができる、5−ホルミルテトラヒドロ葉酸に対する状況と大違いである(ヨーロッパ特許第0755396号明細書)。5−ホルミルテトラヒドロ葉酸溶液の場合、シトラートが加水分解及び基本骨格の酸化開裂を減少させ、したがって生成物、たとえばp−アミノベンゾイルグルタミン酸及びプテリン−及びテトラヒドロプテリン誘導体の形成を減少させる。これに反して,塩基性pH域でMTHFの場合、シトラートはMTHF分子からホルムアルデヒドの離脱(加水分解)を阻止する。このことが、ホラート化合物として分類される、これら2つの化合物を挙動の点で著しく、驚くほど区別させる。
本明細書に引用されたすべての特許出願、特許及び文献を、本願に引用して援用する。
一般的又は具体的に記載された本発明の生成物及び(又は)処理条件を下記例に記載したものと置き換えることによって、下記例を同様な結果をもって実施することができる。同様に、次の具体的な実施態様は単に例示するものであって、決して残りの開示に限定を与えるものではない。
5,10-メチレン-(6R,S)-テトラヒドロ葉酸を含む凍結乾燥物
9900 mlの水をアルゴンで飽和する。421.9 gのクエン酸を攪拌しながら完全に前記水に溶解させる。232.0 gの 5,10-メチレン-(6R,S)-テトラヒドロ葉酸, カルシウム塩を添加する。PH を水酸化ナトリウム水溶液で8.0に調整する。 その結果 5,10-メチレン-(6R,S)-テトラヒドロ葉酸を徐々に溶解させる。その後, pH値を水酸化ナトリウム水溶液で 8.5に調整する。溶液を滅菌条件下に濾過し、ついで薬瓶1個あたり5.0 mlで10 mlのガラス製薬瓶に入れる。 その後, 溶液を凍結させ、ついで凍結乾燥させる。
5,10-メチレン-(6R,S)-テトラヒドロ葉酸を有する薬瓶が得られる。
